The purpose request is to address the growing levels of traffic, particularly truck traffic, traveling through the city and to provide additional access to a proposed industrial park south of the existing industrial park. The Department's study identified several current and projected deficiencies within the study area. The intersection of US 41/SR 7 with SR 37/76 and the intersection of CR 135/SR 76 with SR 37 west of downtown are projected to exceed capacity by 2020. The intersection of CR 216 with US 41/SR 7 is also expected to exceed capacity by 2020. Two existing operational deficiencies were noted in the study: queuing problems on SR 37/76 near Burwell Avenue, US 41/SR 7 and Parrish Avenue as well as a turning problem at the intersection of CR 135/SR 76 with SR 37. Deficiencies were also identified along the arterial of SR 37/ SR 76. The sections of SR 37/SR 76 currently function at an unacceptable LOS between Burwell Avenue and Parrish Avenue. This section of state route is expected to function at an unacceptable level in 2020 even with a bypass in place. Neither of two proposed bypasses will divert enough traffic from SR 37/SR 76 in the downtown area to allow the route to function at an acceptable LOS. The "Bypass Via CR 216" is projected to divert 3,200 vehicles per day from SR 37/SR 76 and the "Southern Bypass" is only expected to divert 1,800 vehicles per day. The diverted traffic would account for less than 20% of the traffic in the downtown area. The section of state route between Burwell Avenue and Parrish Avenue will still function at a LOS F with either of the bypasses in place. Several of the problems identified in this study will be remedied by projects that are currently programmed. The problems identified at the intersection of CR 135/SR 76 with SR 37 should be remedied with the I-75 interchange project (IM-STP-75-1 (193)). Office of Planning Adel Bypass This project will also widen SR 37 from the interchange to CR 135/SR 76. The projected problem with the intersection of US 41/SR 7 with SR 37/SR 76 exceeding capacity by 2020 and the unacceptable LOS of SR 37 between Burwell Avenue and Parrish Avenue will be addressed with project MLP-37 (52) once constructed. The signal upgrade project (STP-0002-00 (711)) will address the queueing problem between Burwell Avenue and Parrish Avenue. CR 135/SR 76 @ SR 37 Burwell Ave. @ SR 37/76 Parrish Ave. @ SR 37/76 SR 37/SR 76 @ US 41/SR 7 Bypass Via CR 216 Proposed Industrial Park CR 216 @ US 41/SR 7 Southern Bypass Planning does not recommend constructing a bypass at this time. The estimated cost for the bypass is between ten to fifteen million dollars to construct and an additional five million dollars (the cost of project MLP-37 (52)) would still be needed to address the problems in the downtown area. Planning recommends that Traffic Operations look at the intersections at Burwell Avenue, US 41/SR 7 and Parrish Avenue to address queuing problems along this section of SR 37 when the signals are upgraded under project STP-0002-00 (711). We also request that Traffic Operations evaluate the intersection at CR 216 and US 41/SR 7 when development of the southern industrial park begins. Office of Planning Adel Bypass 9/18/02 I. Introduction and Purpose: The City of Adel has requested the Department to study the construction of a bypass around the southern edge of the city. The purpose of this bypass is to address the growing levels of traffic, particularly truck traffic, traveling through the city and to provide additional access to a proposed industrial park to be located on US 41/SR 7 south of the existing industrial park.. II. Regional Background: The City of Adel is the county seat of Cook County, which is centrally located in southern Georgia just north of Valdosta (See Figure 1). According to the 2000 Census, the population of Cook County reached 15,771 and experienced 17.2% growth during the 1990s. Meanwhile, the City of Adel grew by 4.2% to a population of 5,307. Although not quite as strong as the statewide rate of 26.4%, this growth is evidence of the growing economy in the area. See Table 1 for more detailed information on the growth in population. Figure 1: Cook County 1970 1980 1990 2000 % Change (90-00) Adel 4,972 5,592 5,093 5,307 4.2 Cook Co. 12,129 13,490 13,456 15,771 17.2 Georgia 4,589,575 5,463,105 6,478,179 8,186,453 26.4 Table 1: Population Growth According to the 2000 Census, 29.1% of the residents were black and 67.9% were white. This compares to a statewide average of 65.1% white and 28.7% black. Out of the total adult population, 34.6% had completed high school, which is greater than the statewide average of 29.6% in 1990. The median household income Office of Planning 1 Adel Bypass 9/18/02 in Cook County was $26,448 in a 1997 estimate. The statewide average was $36,372. Adel has experienced a high level of industrial growth in recent years, as several companies have been attracted to the existing industrial park in southern Adel. This industrial park is located just north of Old Quitman Rd. (CR 216) near Exit 37 on I-75. At the site, JM Manufacturing built the largest PVC pipe manufacturing facility in the world; the plant is expected to employ around 600 once current expansion plans are complete. Other companies that have recently located facilities in Adel include Matrix (formerly Hebel Southeast) and MBCI. As these and other companies located in Adel, the city proposed a 2000-acre industrial park expansion for future development. This expansion will be located south of the existing park and east of the Norfolk Southern rail line with frontage on either side of US 41/SR 7 (See Figure 2). III. Existing Infrastructure: Roadway Characteristics: Three state routes and an interstate form the backbone of the roadway network in the City of Adel (See Figure 2). State Route 37 is the only east-west route through Adel. Connecting with Moultrie to the west and Lakeland to the east, the route traverses the heart of the city as Fourth Street. The road consists of two lanes with an average travel width of 24 feet. The right-of-way averages around 100 feet east of US 41/SR 7, and between 60 and 70 feet between US 41/SR 7 and the interstate. State Route 76 connects Adel with Nashville to the north and Quitman to the south. This route intersects SR 37 east of the city and runs common with SR 37 through Adel until just before the interstate. SR 76 is a two-lane road with a 100-foot typical right-of-way and a 24-foot typical travel width. US 41/SR 7 connects Adel with Sparks and Tifton to the north and Hahira to the south. The typical section includes two lanes with a travel width of 22 to 26 feet and a 60 to 70 foot rightof-way. It intersects SR 37/76 inside the Central Business District. Office of Planning 2 Adel Bypass 9/18/02 Interstate 75 is the interstate serving Adel. I-75 connects the city with Tifton, Macon, and Atlanta to the north and Valdosta and Florida to the south. The typical section of the freeway includes four lanes with a 48-foot travel width. The average right-of-way is 300 feet. The interstate has an interchange with SR 37 west of the Central Business District (exit 39), and another with Old Quitman Road, CR 216 (exit 37). This county road is a two-lane road with an 80-foot right-of-way and a travel width of 20 feet. CR 216 connects US 41/SR 7 with I-75, passing the industrial park and crossing the Norfolk Southern mainline along the way. Figure 2: The City of Adel Alternative Modes: Norfolk Southern and the Georgia & Florida Railnet provide Adel with rail service. The Norfolk Southern mainline connects the city with Macon, Atlanta, and Florida. The Georgia & Florida Office of Planning 3 Adel Bypass 9/18/02 Railnet interchanges with Norfolk Southern at Adel. The rail line extends south to Quitman, where it interchanges with CSX. Trackage inside the city includes several industrial spurs, a wye south of Fifth Street, and a yard stretching north from CR 216 through the Central Business District. Of the 31 public railroad crossings in the city, ten are protected by gates, ten have crossbucks, and the remainder are either unmarked or have stop signs. The Cook County Airport also serves Adel. Located west of Adel on SR 37, this airport has recently received numerous grants for improvements. The Adel airport is a General Aviation Airport that handles charted flights. The nearest commercial airport that handles commercial passenger flight is in Valdosta. A portion of the State's Central Bike Route passes through Cook County. The Central Bike Route uses a segment of SR 37 and Cook County Roads 15, 242 and 243 west of Adel. The bike route is a north south route that begins at the Florida State line in Lowndes County and ends north of Atlanta. Construction Activities: The current Construction Work Program includes several projects in the Adel area. The largest project in the area is the reconstruction of I-75 along the entire length of the county. The project will widen the interstate from four to six lanes. A related project involves widening SR 37 to four lanes at I-75 and replacement of the overpass, IM-STP-75-1 (193). Between this project and just west of US 41/SR 7, there are plans to widen SR 37. This project, MLP-37 (52), has stalled due to concerns about the effects of the widening on adjacent historical structures. In addition to the roadway projects, there are two rail crossing projects and a signal project. The rail projects (STP-0000-00 (655) and (656)) will improve the rail crossings at Talley St. (CS 695) and Eighth St. (CS 678). The signal project (STP-0002-00 (711)) will upgrade the signals on SR 37/SR 76. IV. Traffic Characteristics: Traffic Patterns: The heaviest traffic volumes inside Adel are found on the four major routes, I-75, SR 37, SR 76 and SR 7, that serve the city. Office of Planning 4 Adel Bypass 9/18/02 I-75, which traverses the city west of the Central Business District, had an Average Annual Daily Traffic volume approaching 35,000 in the year 2000. SR 37 handles 12,460 vehicles per day between the interstate and US 41/SR 7. East of this point, traffic volumes taper to 2,080 just past the SR 37/76 split. The volume on SR 76 east of the split is 3,170. West of the interstate, SR 76 has an AADT of 3,452, and the volume increases to 5,585 east of I-75. Traffic volumes on US 41/SR 7 reach 11,073 inside the Central Business District, but diminish to near 2,200 south of CR 249. CR 216 connects US 41/SR 7 with I75 south of the city and handles volumes around 3,300. See Figure 3 and Appendix A for more information about traffic volumes in Adel. TC141 12460 (19362) TC261 4860 (8524) TC172 34880 (56405) TC143 12680 (17230) TC158 5530 (5585) TC254 3300 (5200) TC145 8290 (12612) TC112 8360 (11073) TC109 5600 (8271) AADT in Adel 2000, (2020) TC 147 6180 (9353) TC 149 2080 (3658) TC149 2080 (3658) See Appendix A for current and projected traffic volumes. Figure 3: Traffic Volumes in Adel Office of Planning 5 Adel Bypass 9/18/02 Several major traffic generators exist in the industrial area in southern Adel. In addition to through traffic, local industries generate up to 320 trucks daily and 616 trucks weekly, as reported by the City. Truck traffic in the southern end of the industrial park is concentrated on CR 216, which provides a direct connection to the interstate and US 41/SR 7. Railroad traffic is becoming a major concern. Local industries and the Norfolk Southern yard within downtown Adel generate a large amount of rail traffic in the area. In the year 2000, an average of 16 trains traveled through the city per day. The Federal Railroad Administration reports that through trains amount to nearly seven during the day and six at night near SR 37/76. In addition, local switching produces up to twelve movements per day and seven at night. This traffic combined with the 31 public at grade crossings inside the city snarls traffic by effectively closing crossings for extended periods every day. On occasions, delays at these crossings can exceed 30 minutes per day. The rail traffic is potentially a safety hazard, as emergency vehicles have no way to cross the railroad when a train is passing. Level of Service: Ten intersections were examined in this study. All were found to be functioning at acceptable levels. Four of these intersections were signalized and the rest were unsignalized. The signalized intersections were all along SR 37 and included intersections with US 41/SR 7 (station 9007), Burwell Avenue one block west of US 41 (9006), Parrish Avenue one block east of US 41 (9008) and SR 76 west of downtown. Figure 3 shows the locations of these intersections. All signalized intersections had volume to capacity ratios less than 1.0, and thus were under capacity. Most of the unsignalized intersections had Levels of Service (LOS) of B or above. The eastbound approach of the intersection at CR 216 and US 41/SR 7 (9002) had the lowest LOS at C. See Appendix B for a detailed description of Level of Service and Appendix C for more detailed information about current and projected Levels of Service at the intersections. Arterial Levels of Service throughout the city were also examined. Most of the arterial routes and freeways in the city were functioning at LOS B or above. The lowest Levels of Service were found on SR 37/76. This route operates at an unacceptable LOS E or worse between Burwell Avenue and Parrish Office of Planning 6 Adel Bypass 9/18/02 Avenue. Along this section of state route there are three signalized intersections located less than 320 feet apart. East of Burwell Avenue to the intersection with SR 76, the LOS is A. US 41/SR 7 has a LOS C north and south of SR 37/76 (TC stations 114 and 112). CR 216 is functioning at a LOS A. See Figure 3 for the locations of these stations. Accident Rates: Overall accident rates within the City of Adel did not exceed the statewide averages. Analysis of the accident data has also shown a decline in accident rates within the city between the years 1996 and 1998. SR 37 and US 41/SR 7 had the highest accident rates within the city, which were comparable to the state average. The highest rates outside Adel were found on US 41/SR 7 south of the city. The accident rates on this section were higher than the statewide averages. See Appendix D for detailed information about the accident rates. Tractor-trailer accidents are increasing along SR 37. Sixteen accidents involving tractor-trailers occurred during 1999 and 2000. In comparison, thirteen tractor-trailer accidents occurred between 1996 and 1998; this figure includes eight accidents reported in 1996, four in 1997, and one in 1998. Nearly half of the year 1999 and 2000 accidents involved trucks exiting the interstate and turning onto SR 37. This should be alleviated with the reconstruction of the ramp intersections and widening of SR 37 as a part of the interchange reconstruction project, IM-STP-75-1 (193). Truck traffic within the city is also creating safety concerns at the intersection of SR 37 and SR 76 inside Adel. Traffic traveling between SR 76, the industrial park, and I-75 must turn at this intersection. This intersection has limited turning radii, which causes problems for trucks turning between both the southbound and northbound and the eastbound approaches. This is primarily due to the sharp angle that SR 76 intersects SR 37. According to data obtained from the Federal Railroad Administration (FRA), the highway-rail crossing collision rate of 0.0968 accidents per crossing within the city exceeded both the statewide and national averages for 1999, which were 0.0146 and 0.0221. All three of the accidents that occurred during 1999 took place at either Talley St. (723349V) or West 9th St. (723323T). These two crossings and a third on Industrial Park Office of Planning 7 Adel Bypass 9/18/02 Dr. (723322L) are among the 100 most dangerous crossings in the state, based on predicted collision rates calculated by the FRA. Two state projects will upgrade the crossing at Talley St. and at 8th Street. Queues on SR 37/76 at the Burwell Ave. (9006), US 41/SR 7 (9007), and Parrish Ave. (9008) intersections are creating another safety hazard. The short distances between these intersections leave little room for eastbound and westbound queues without blocking adjacent intersections. Furthermore, queues on the eastbound approach at Burwell Ave. can extend over the Norfolk Southern railroad tracks. In the year 2000, five accidents that occurred at the crossing involved queues extending over the tracks on the eastbound approach of the Burwell Ave. intersection. Projections: Traffic volumes were projected for the year 2020 based on exponential regression of volume data gathered between the years 1986 and 2000. See Appendix A for more details about the projected traffic volumes and the average traffic growth rates. The projected Levels of Service were based on the projected traffic volumes (See Appendix C). The analysis of the traffic volumes showed that overall traffic growth averaged just less than 3.0% during the fifteen-year period. The greatest amount of traffic growth centered on SR 37 east of US 41/SR 7 and the roads providing access to the interstate. Traffic growth on I-75 averaged around 3.5%. The projections indicate traffic volumes on SR 37 nearing 20,000 east of the interstate and an AADT of 11,073 on US 41/SR 7 just south of the intersection with SR 37. The projected growth on SR 76 reaches 5,585 east of the interstate. The traffic growth will cause a general deterioration in the Levels of Service (LOS) of intersections within the study area. The traffic volumes on the eastbound approach at the intersection of CR 216 and SR 7 (9002) are expected to exceed capacity, although the Levels of Service at the intersections with the Exit 37 ramps (9003) do not fall below LOS B. The intersection locations are indicated in Figure 3. At the SR 37 exit on I-75 (9004), both northbound and southbound exit ramp volumes exceed capacity; however, this projection does not consider improvements made as part of the proposed SR 37 Office of Planning 8 Adel Bypass 9/18/02 widening project (IM-STP-75-1(193)). The signalized intersections along SR 37 also did not fare well with the increasing traffic volumes. The SR 37 and SR 76 intersection inside the city limits (9005) is projected to be near capacity, while the US 41/SR 7 intersection (9007) exceeds capacity. The N. Burwell Ave. (9006) and N. Parrish Ave. (9008) intersections are projected to be under capacity. The arterial Levels of Service will also deteriorate due to the increasing traffic volumes. SR 37/76 is projected to fall to LOS F between Burwell Avenue and Parrish Avenue and LOS C west of CR 135/SR 76. US 41/SR 7 is projected to reach LOS D just south of SR 37/76 (112) and LOS C elsewhere inside the city (114 and 109). The Levels of Service on I-75 will fall to LOS D north of CR 216 (172 and 174) by the year 2020. CR 216 will operate at LOS B (254). V. Analysis: Current and projected conditions inside the City of Adel indicate that operational conditions are either currently or in the future at unacceptable levels. Traffic inside the city has increased greatly due to growing levels of through traffic and an expanding industrial center south of the Central Business District. The increased level of through traffic is focused on SR 37/76. This route serves as the only route for traffic traveling between the interstate in Adel and points east. According to projections, traffic levels on this route will approach 20,000 vehicles per day just east of the interstate and around 12,600 east of US 41/SR 7 by 2020. The Levels of Service along the route fall to LOS F east of the interstate and LOS D just east of US 41/SR 7. Truck concentrations on this route approach 8% of the total traffic near the SR 37 and SR 76 intersection east of the city. The projected volumes will cause several intersections along the route to exceed or near capacity. The SR 37/76 and US 41/SR 7 intersection (9007) and the intersection of SR 37 and SR 76 inside the city (9005) are projected to exceed capacity. The exit ramp intersections at Exit 39 (9004) are also expected to exceed capacity; however, these intersections will be rebuilt as part of an interchange reconstruction project. Office of Planning 9 Adel Bypass 9/18/02 Safety has also become a concern, as Adel has become congested with trains, cars, and trucks. Queuing problems are evident on SR 37/76 near Burwell Ave., US 41/SR 7, and Parrish Ave. Queues at these intersections on the westbound and eastbound approaches are blocking adjacent intersections, compounding the traffic problem. This has been a factor in several accidents in the area, particularly at the railroad crossing just west of Burwell Ave., where the eastbound approach of SR 37/76 can block the crossing. The intersection of SR 37 with CR 135/SR 76 just east of the interstate also has deficiencies. Truck trafic traveling from CR 135 or SR 76 turning west toward the interstate is encountering turning problems due to the tight turn required at this point. See Figure 2 for the location of this intersection. The other major source of traffic growth, the industrial park, compounds this problem by not only providing increased truck traffic, but also commuting traffic. Much of this growth has affected Old Quitman Road (CR 216), which connects the industrial park and US 41/SR 7 to Interstate 75. Volumes on this road are expected to reach 5,200 vehicles per day by the year 2020. The recent proposal for a new industrial park along US 41/SR 7 has even greater consequences, as CR 216 will provide the only access between the new park and the interstate without a long detour through the Central Business District. This will also increase traffic levels at the intersection of CR 216 and US 41/SR 7. This intersection is projected to exceed capacity by 2020, even without the new industrial park. Compounding this situation, rail traffic is a major concern in the area. With increasing roadway volumes and heavy rail traffic, the numerous grade crossings provide a potential safety risk not only within the Central Business District but also near the industrial park. CR 216 is at the extreme southern end of a Norfolk Southern rail yard that extends northward through the city. Through movements and local switching cause the grade crossing on Old Quitman Road to be closed for extended periods during the day. Rail traffic, averaging around 16 trains per day, closed area rail crossings for nearly half an hour each day during the year 2000. This situation is of particular concern on SR 37/76, as eastbound queues often extend across the railroad crossing west of the Burwell Ave. intersection. Office of Planning 10 Adel Bypass 9/18/02 VI. Alternatives: Two alternatives were proposed by the City of Adel to address deficiencies within the study area. Both alternatives seek to alleviate the traffic problems by providing alternate routes for traffic in the area. Bypass via CR 216: The first alternative provides a bypass around the southern end of the city via CR 216. Starting at the junction of SR 37 and SR 76 (see Figure 4), the route involves a reconstructed intersection (1) and new construction between the intersection and CR 216 (2). Just past the intersection with SR 7, an overpass (3) carries the route above the Norfolk Southern mainline. The construction of the overpass will allow for the closure of the grade crossing and a section of CR 216. EXIT 39 EXIT 37 Figure 4: Proposed Alternatives Office of Planning 11 Adel Bypass 9/18/02 This alternative may require Industrial Park Drive to be relocated so as to provide improved access into the Industrial Park (4). The alternative ends just past I-75 Exit 37 (5). This interchange may require modifications to handle increased traffic loads. Land use along this alternative is predominantly agricultural east of the railroad. Some residential development exists north of the proposed alignment just to the east of SR 7. West of the railroad, the bypass travels through the industrial park. Several vacated gas stations are located near the interstate on CR 216. Construction of this proposed bypass is estimated to cost around $8,966,000 (see Appendix E). The new construction on this alternative travels through largely level terrain, and CR 216 has an 80-foot right-of-way and a 20-foot travel width. This alternative will require realignment of SR 76 at SR 37, 2.75 miles of new construction between the intersection and CR 216, and reconstruction of CR 216 east of I-75. The typical section of this proposed roadway includes two twelve-foot lanes in a 100-foot right-of-way. This alternate also requires the construction of a bridge that spans the railroad and US 41/SR 7 since there is not enough room between the railroad and US 41/ SR 7 to get the bridge up over the railroad and back down to form an at-grade intersection with US 41/SR 7. This bypass will accommodate local traffic near the industrial park and through traffic traveling between I-75 and the east junction of SR 37/76. This route is expected to carry around 3,200 vehicles daily east of US 41/SR 7. West of US 41, the route is expected to carry nearly 8,400 vehicles per day by 2020. Westward Extension: An option of extending this first alternative west of I-75 to SR 76 has also been proposed. This westward extension follows the existing CR 216 south to CR 149 (6), and then follows CR 149 westward until bearing off to the northwest to avoid a sharp curve and several structures (7). Just before the railroad crossing, the route intersects CR 149 again (8) and follows the existing alignment to the intersection with SR 76. Office of Planning 12 Adel Bypass 9/18/02 This route passes through mainly agricultural areas with some residential land use along the existing CR 149. CR 216 has an 80-foot right-of-way and a 20-foot travel width. CR 149 is unpaved, with a 20-foot travel width and a 40-foot right-of-way. The cost of the extension and the first alternative is estimated to be $10,329,000, with the extension costing $1,363,000. This includes reconstruction of CR 216 between I-75 and CR 149, reconstruction and paving parts of CR 149, new construction east of the railroad, and intersection improvements at SR 76. This roadway would have a typical section consisting of two twelvefoot lanes in a 100-foot right-of-way. Improvements to the railroad crossing on the existing CR 149 would also be needed. This extension allows for improved access between I-75 and SR 76 west of the city. Through traffic on SR 76 can also bypass the city on this route in conjunction with the CR 216 route. Based on year 2020 projections, this road is expected to handle nearly 1,300 vehicles per day. Southern Bypass: The second alternative for the proposed truck route involves a bypass even further to the south of the city. This route travels south from the intersection of SR 76 and SR 37 (1) as shown in Figure 4. Following the proposed alignment of the first alternative to the southwest, this alternative bears off to the south on a new alignment south of CR 156 (9). The bypass then crosses CR 249 and CR 25 before turning west. After passing US 41/SR 7 and crossing the railroad (10), the alternative intersects I-75. This alternate will require an interchange at this location to provide access onto I-75 (11). This proposal includes a connection to CR 20 (11) and realignment of CR 242. Land use along this route is mainly agricultural to the north of CR 249. Residential land use is found near CR 249 and CR 26, and a new industrial park is planned near US 41/SR 7. This entire route involves new construction through level terrain. This alternative also involves a potential railroad overpass just west of US 41/SR 7, realignment of CR 20 and CR 242, an interchange with I-75, and reconstruction of the intersection of SR 37 and SR 76 east of the city. The total cost of this bypass is estimated to be $15,965,000. A typical section of this proposed roadway consists of two twelve-foot lanes in a 100-foot right-of-way. See Appendix E for more details. Office of Planning 13 Adel Bypass 9/18/02 This bypass will accommodate traffic traveling between I-75 and SR 37/76 east of the city. Year 2020 projections indicate that nearly 1,800 vehicles will use this route each day. VII. Conclusion: The study identified several current and projected deficiencies within the study area. The intersection of US 41/SR 7 with SR 37/76 and the intersection of CR 135/SR 76 with SR 37 west of downtown are projected to exceed capacity by 2020. The intersection of CR 216 with US 41/SR 7 is also expected to exceed capacity by 2020. Two existing operational deficiencies were noted in the study: queuing problems on SR 37/76 near Burwell Avenue, US 41/SR 7 and Parrish Avenue as well as a turning problem at the intersection of CR 135/SR 76 with SR 37. At the CR 135/SR 76 intersection with SR 37 trucks are having problems negotiating the turn movement from the side streets, CR 135 and SR 76, onto SR 37 traveling west toward the interstate and vice versa. Deficiencies were also identified along the arterial of SR 37/ SR 76. The sections of SR 37/SR 76 currently function at an unacceptable LOS between Burwell Avenue and Parrish Avenue. This section of state route is expected to function at an unacceptable level in 2020 even with the proposed bypass constructed. The unacceptable LOS is largely due to the close proximity of the signalized intersections, Burwell Avenue, US 41/SR 7 and Parrish Avenue, to each other. Neither of the proposed bypasses will divert enough traffic from SR 37/SR 76 in the downtown area to allow the route to function at an acceptable LOS. The "Bypass Via CR 216" is projected to divert 3,200 vehicles per day from SR 37/SR 76 and the "Southern Bypass" is only expected to divert 1,800 vehicles per day. The diverted traffic would account for less than 20% of the traffic in the downtown area. The section of state route between Burwell Avenue and Parrish Avenue will still function at a LOS F with either of the bypasses in place. Several of the problems identified in this study will be remedied by projects that are currently programmed. The problems identified at the intersection of CR 135/SR 76 with SR 37 should be remedied with the I-75 interchange project (IM-STP75-1 (193)). This project will also widen SR 37 from the Office of Planning 14 Adel Bypass 9/18/02 interchange to CR 135/SR 76. The expected problem with the intersection of US 41/SR 7 with SR 37/SR 76 exceeding capacity by 2020 and the unacceptable LOS of SR 37 between Burwell Avenue and Parrish Avenue will be taken care of with project MLP-37 (52) once a viable concept is developed. The signal upgrade project (STP-0002-00 (711)) will address the queueing and should improve the current LOS between Burwell Avenue and Parrish Avenue. The remaining operational problem at the intersection of CR 216 with US 41/SR 7 that was identified in the study is not expected to exceed capacity any time in the near future. This intersection can be looked at prior to the development of the proposed southern industrial park on US 41/SR 7. VIII. Recommendations: Although a viable concept has not been developed for the project to widen SR 37, Planning does not recommend constructing a bypass. The bypass would cost between ten to fifteen million dollars to construct and an additional five million dollars(the cost of project MLP-37 (52)) would still be needed to address the problems in the downtown area. Planning recommends that Traffic Operations look at the intersections at Burwell Avenue, US 41/SR 7 and Parrish Avenue to address queuing problems along this section of SR 37 when the signals are upgraded under project STP-0002-00 (711). We also request that Traffic Operations evaluate the intersection at CR 216 and US 41/SR 7 when development of the southern industrial park begins.

Office of Planning II Adel Bypass 9/18/02 Appendix B Explanation of Level of Service (LOS) Office of Planning III Adel Bypass 9/18/02 Level of Service (LOS): Level of Service is a qualitative measure describing operational conditions within a traffic stream. Level of Service (LOS) describes the overall condition of these conditions in terms of such factors as speed, traffic density, travel time, comfort and convenience, and safety. The six letters between A and F represent the possible values of the Level of Service. A LOS A represents the best operating conditions, while a LOS F describes the worst conditions. In an unsignalized intersection, Level of Service corresponds to the expected delay to minor street. Little or no delays are expected with a LOS A. Short delays are expected with a LOS B. LOS C is the lowest Level of Service considered acceptable by the Georgia DOT and represents an average delay. LOS D and LOS E represent longer expected delays. When the Level of Service is F, the traffic flow shuts down, and delays at an intersection are extremely long. For planning purposes, signalized intersections are measured in terms of the ratio of volume to capacity. This compares the current and projected traffic volumes with the capacity of the roadway configuration.
