Agenda 11-14-23; 7-b - US 70 Multimodal Corridor Plan

64 lib All twelve signalized intersections analyzed operate acceptable overall LOS during peak hours,and conditions are generally similar overall between both peak hours.US 70 generally experiences a better LOS than the cross streets at each intersection.Most side streets operate at an acceptable LOS during both peak hours except for a few intersections between Durham and Hillsborough.Mt.Herman Church Road and Pleasant Green Road operate at LOS F during both peak hours. At Lawrence Road,the northbound approach operates at LOS E during the AM peak,and the southbound approach operates at LOSE E during the PM peak hour. AW Between the Mt.Herman Church Road/Pleasant Green Road and Lawrence Road intersections is the unsignalized US 70 Bus/Palmers Grove Road intersection.The NB US 70 Bus approach operates at LOS F during both peak hours(with worse delay in the PM), and the SB Palmers Grove Road approach operates at the LOS D during the AM peak hour and LOS E during the PM peak hour.These LOS deficiencies are due mainly to vehicles waiting to turn onto US 70,although crossing and right-turning vehicles contribute. Combined with heavy peak-hour traffic,high speeds and some visibility constraints create long delays as drivers wait for adequate gaps in traffic. Due to their proximity to at-grade rail crossings,several signals in Mebane(Moore Street,3rd Street,4th Street,and 5th Street)require interconnection with the rail crossing signals and crossing gates to preempt normal traffic signal operation in the presence of a train.This preemption prevents conflicting signal combinations between the relevant traffic control devices. LOS is not calculated for preemptive operation,but such conditions obviously add delay and can create long vehicle queues. �h 4nhnhnhnhns `•h+h+' t, t u' u t, u � AH i � f ut " {5 Ji i 8 62 US 70 Multimodal Corridor Study Existing Conditions Report
