Based on Streetlight data collected by the design team and verified by Inrix data collected by PennDOT for the existing conditions, when traffic leaves U.S. 1 southbound via the southbound service road and exits onto Bellevue Avenue, 49.0% in the AM peak hour and 60.4% in the PM peak hour are traveling toward Newtown with the second highest portion of traffic being residential traffic living in the adjacent neighborhoods.

The second largest portions of the traffic in the AM peak hour are split traveling north or south on PA 413 and the second largest portions of the traffic in the PM peak hour are split between the adjacent neighborhoods and heading north on PA 413 toward Newtown. The following graphics depict the breakdown for all traffic exiting U.S. 1 via Bellevue Avenue. Origin-Destination Data
All of this data was coupled with PennDOT’s actual traffic counts to better understand current traffic patterns and calibrate the proposed traffic model.
