WSP covered the cost for the data processing and collaborated with Imperial Traffic & Data Collection, which set up and provided their measuring equipment for free. Additionally, the Bicycle Coalition of Greater Philadelphia assisted with manual counts and verification.
“The wealth of data collected by WSP for the recently completed report will now be used to assist the city of Philadelphia, Delaware Valley Regional Planning Commission, and program advocates to substantiate the impact of the closure and how the road can be used after the pandemic,” Cowan said.
Although a shared-use path parallels Martin Luther King Jr. Drive and the popular Schuylkill River Trail runs along the other side of the river, both paths are narrow and challenging to run, ride or roll. They also draw considerable foot and bike traffic under normal conditions, making them less safe and unaccommodating to social distancing.
“It was the city’s hope that the closure of MLK Drive would help alleviate the overcrowding on the Schuylkill River Trail and serve to be a popular alternative,” Cowan wrote in his final report.
Video processed counts of pedestrians and bicycles were conducted in both directions from sunrise to sunset at two locations along the road. This allowed for a breakdown of specific uses for the road – inline skaters, adult and child cyclists, pedestrians and runners. The data also factored in weather conditions, such as hot summer temperatures and precipitation.
Although Schuylkill River Trail usage increased during the pandemic, those increases were significantly curbed by the thousands of residents who chose to use the closed roadway instead.
In light of the success of the closure, supported by the data compiled by WSP, Philadelphia officials will face a significant decision once the pandemic has subsided.
While commonly used as an analytical method that helps the designer and public understand the amount of congestion and delay experienced along a road or at an intersection, the level of service (LOS) metric can also be applied to shared use facilities.
“The City of Philadelphia will eventually move towards a decision of keeping MLK Drive closed, reopening it, or repurposing the lanes,” Cowan said. “An LOS analysis can be used to inform that decision.”
Cowan prepared the study with research assistance from Christopher Blakely, WSP civil/highway engineer; and Elizabeth Andrew, WSP senior traffic engineer.
