Policy on Geometric Design of Highways and Streets 1994" published by American Association of State Highway and Transportation Officials, were used. Based on these methodologies, it is recommended that the following corner sight distances be supplied at each of the driveways: • Sight distance to the right : 660 ft(based on design speed of 60 mph from Caltrans Highway Design Manual 4h Edition) • Sight distance to the left : 600 ft(based on design speed of 60 mph from AASHTO) Using these sight distances, and assuming the driver eye is located 15 ft. from the edge of the traveled way, it is recommended that the following sight distance triangles be supplied (and kept free of obstructions) at each of the driveways: • Sight distance triangle to the right : Triangle comprised of 15 ft. along the driveway and 300 ft. along the near side edge of pavement • Sight distance triangle to the left : Triangle comprised of 15 ft. along the driveway and 430 ft. along the near side edge of pavement Cumulative Conditions Intersections All three study intersections (which are signalized) were found to operate acceptably at LOS D or better for Cumulative No Project, and Cumulative plus Project conditions during both the PM peak hour and Sunday peak hour. Northern and southern access driveways to the project site would also operate at acceptable LOS B or better for Cumulative plus Project conditions during both the PM peak hour and Sunday peak hour with Lower Sacramento Road having a raised median with restricted left tum control from the access driveways. Roadways All of the roadway sections were found to operate acceptably at LOS C or better for Cumulative weekday conditions and LOS B for Sunday daily conditions except for Lower Sacramento Road within the City of Stockton. The 4-lane divided section of Lower Sacramento Road within the City of Stockton would operate unacceptably at LOS F for weekday daily conditions and acceptably at LOS B for Sunday daily conditions. These results are based on the assumption that the programmed and planned improvements would be completed by the year 2020. Based on the discussion with the City personnel, the city of Stockton currently does not have programmed improvement plans for Lower Sacramento Road within the City. However, consideration should be given to eventually widening this section of Lower Sacramento Road to match the 6-lane configuration which it is assumed will ultimately be in place within the County. A field survey shows that the roadway does have adequate right-of-way to accommodate one additional through lane in each direction. If widened to 6-lanes, this section of Lower Sacramento Road would operate at LOS C for both Cumulative no project and plus project conditions during a typical weekday.
