In 2017, the Delaware Valley Regional Planning Commission (DVRPC) performed a “Level of Traffic Stress” (LTS) analysis of the five Pennsylvania counties in the Philadelphia region.
Using a multi-faceted set of data (road widths, shoulders, bike lanes, speed limits, etc), the LTS analysis separates every road in the region into one of four levels, from lovely local roads to nightmare highway hellscapes.
Previously, DVRPC wasn’t able to perform the analysis for the entire region. This week, that changed. Now local bike/ped advocates have a great tool for advocating for road improvements, no matter which side of the Delaware River they live on! Click here to see the results! Keep in mind that the map has many “layers” that you can toggle on and off to look at different data.
As anyone who’s tried to bike or walk for any distance in the average suburb can attest, the lovely local road network is pretty disconnected, leaving hundreds of low-stress “islands” in the region.
The map screenshot above is demonstrative of the concept. Camden’s dense street networks is clearly shown, but its isolation from the rest of NJ is also quite clear: I-295, I-76 and Rt. 73 have the City completely boxed in. Also, due to quirks of street grids not aligning, much of Pennsauken and Merchantville are not connected to Camden’s LTS grid.
In Philadelphia, Cobbs Creek forms a hard line between the City and Delaware County: there is not a single low-stress road connection between them.
This dataset is something we have advocated for since 2016, so we’re excited that it’s at last complete. Notice anything missing or incorrect in the analysis? Click here to suggest changes to DVRPC.
Thank you! This is just what I was looking for the other day. Very helpful. Although, I’m sure other people are smarter than me, but it took me a bit to figure out the initial setting is for connectivity priority – which really wasn’t my interest in this particular case, and I needed to change the Layering to see the Level of Stress. (And Level of Stress shown with Bike Facilities gets really confusing because the red for LTS4 is completely opposite of the red for bike lane.) Thanks again for this very timely post!
This is awesome!
