First Avenue Road Diet Designing a “road diet,” or converting a four-lane undivided highway into a three-lane roadway with two travel lanes and a center turn lane or landscaped median can provide safety improvements. The additional space created by the “diet” is converted to other uses, such as bicycle lanes, on-street parking, or landscaped buffer zones for pedestrians and sidewalks. Construction was recently completed on the “road diet” for First Avenue in King of Prussia, PA. First Avenue between North Gulph Road and Allendale Road will comprise a travel lane in each direction with safe, center turn lanes and bike lanes on each side. A mid-block signalized pedestrian crosswalk between 935 and 1000 First Avenue will create a more pedestrian-friendly roadway. Existing Conditions Proposed "Road Diet" Conditions Evidence shows that narrowing the roadway leads to drivers traveling at lower speeds, which reduces the crash frequency and severity. Pedestrians and bicyclists also benefit from the reduced speeds, as well as improved sight distance and shorter roadway crossings. Lansdale Borough Wood-Vine Connector As the appointed traffic engineer in Lansdale, PA, we have designed and implemented numerous traffic and pedestrian improvements. One of the most impactful projects involved establishing an alternate route between West Main and South Board streets. These two roads, along with SEPTA’s regional rail corridor, are part of a triad of vehicular and rail corridors that PennDOT has identified as one of the most complex interactions of train and vehicular traffic in the northeastern United States. By allowing drivers to bypass the Broad/Main Street intersection and the SEPTA rail crossings, the newly established, stop-sign-free route involving reconfigured Vine and Wood streets has provided an alternate course for northbound and eastbound traffic. The new connector enhanced vehicular capacity, improved traffic circulation and enhanced pedestrian safety at the Main Street/ Broad Street intersection, through roadway and sidewalk lighting, decorative crosswalks, a new sidewalk with Americans with Disabilities Act-compliant curb ramps, and a flashing beacon for crossing Main Street.
