An initiative designed to optimise traffic lights on Wellington Road for the benefit of southbound heavy goods vehicles has resulted in time savings of up to 19% following its introduction earlier this year.
Nestrans, the Regional Transport Partnership for Aberdeen City & Shire, funded the project in partnership with the European Interreg project StratMoS as part of delivering a Freight Action Plan. Rab Dickson, Transport Strategy Manager at Nestrans explains the benefits are more than just the saving in journey time. “Two sets of traffic signals now provide additional green-time for HGV’s approaching the junctions at Greenbank Road and Hareness Road, on one of the city’s busiest routes for freight and on a steep incline, resulting in slow moving vehicles often being caught at both sets of lights causing undue delays and resulting pollution with hill starts.”
Before and after surveys were undertaken to ascertain the effectiveness of the scheme to register an approaching vehicle and provide a few additional seconds of green-time to enable their continued movement through the lights in the off-peak period. Average journey times for HGVs were reduced by around 12%, with smaller benefits also being experienced by cars and vans. In the worst-case scenario for the heaviest vehicles, up to 19% reduction in freight journey times was experienced, as well as improvements for all traffic and environmental benefits.
The work has been implemented by Aberdeen City Council and funded by Nestrans through the StratMoS project as one of the pilot freight studies which form part of the region’s Freight Action Plan. A Freight Forum has been developed to identify priorities and ensure delivery of key schemes benefitting the freight industry.
