*Delay of worst movement is reported in place of overall delay at side -street stop -controlled intersections. The need for turn lanes along CSAH 70 was evaluated using the methodologies laid out in the National Cooperative Highway Research Program's Report 457 on the need for major -road turn lanes at side -street stop -controlled intersections. Turn lane warrants were conducted at all stop -controlled site access points for each applicable turning movement. Results of the turn lane warrant analysis are given below in Table 6-1. Table 6-1: Access Point Turn Lane Warrant Analysis Results ScenarioTurn Lane Warrant Result By Intersection• • 1 Scenario 2030 2045 2030 2045 Sunset Avenue & Access A NBR MET MET MET MET EBR MET MET MET MET Main Street & Access B WBR MET MET MET MET EBR MET MET - Main Street & Access D WBR - MET - - NBL - Not Met - Not Met 4th Avenue & Access E SBR - MET - MET NBL - MET - MET 4th Avenue & Access F SBR - Not Met - Not Met NBL - MET - MET 4th Avenue & Access G SBR - Not Met - Not Met The results of the analysis indicate that under both Scenario 1 and Scenario 2, right turn lanes are warranted on all access points along Sunset Avenue and Main Street. Additionally, the access point along 41h Avenue south of Main Street (Access E) meets the warrant for only a southbound right turn lane, while the access points along 41h Avenue north of Main Street (Accesses F and G) meet the warrant only for a northbound left turn lane. Further traffic analysis should be conducted as the site develops to confirm the need for geometric improvements after the access locations and development characteristics have been finalized.
