This report provides a summary of the Bethlehem Pike road diet evaluation, conducted as a second phase to the study, Taming Traffic: Context Sensitive Solutions in the DVRPC Region (#08044) published in December of 2008. The most important recommendation from the 2008 study was to convert Bethlehem Pike’s existing four-lane configuration to a three-lane cross-section with one travel lane per direction and a two-way-left-turn-lane. This report discusses the process and results required by PennDOT for measuring the modeled traffic performance of Bethlehem Pike under a road diet configuration as compared to the existing configuration, with both current and future traffic volumes, and with improvements. The analysis showed that implementing the road diet is reasonable if done with signal and intersection improvements, under both current and future traffic volumes. This concept is ready to be advanced by PennDOT in collaboration with Springfield Township.

Geographic Area Covered: Springfield and Whitemarsh townships in Montgomery County, Pennsylvania

Key Words: road diet, Synchro, SimTraffic, growth factor, taming traffic, CSS, speeding, crashes, safety, analysis, traffic volume, turning movement.
