Project Overview

The project involved the widening of approximately 1.5 miles of Route 202 to provide for a four-lane cross section and auxiliary lanes as well as the reconfiguration of the Route 202/E. State Street partial diamond interchange. Additional improvements included the installation of storm water management facilities, a multi-use trail, sidewalk upgrades, a trailhead parking facility and the installation of upgraded traffic signals and signal communication equipment.

The traffic signal design component of this project focused on the design of Adaptive traffic signal control, ITS devices, and an Ethernet based communications system that communicates with the PennDOT District 6-0 Traffic Management Center (TMC).

TPD completed and obtained Central Office approval of the PennDOT TE-153 (Pennsylvania Adaptive Signal Control System Evaluation) and TE-152 (Traffic Signal Proprietary Item Analysis engineering and Traffic Study) forms based on coordination with the maintaining municipality and District personnel. The information compiled through use of these forms was paramount in determining the appropriate Adaptive control system for the project traffic signals. The Adaptive traffic control system selected for these traffic signals will add to and work with the existing system of over 20 Adaptive controlled traffic signals along the Route 202 Parkway and DeKalb Pike located to the south.

For the corridor widening and reconstruction project, TPD designed two traffic signals, designed adaptive traffic signal control, an Ethernet based communications system that communicates with the PennDOT District 6-0 Traffic Management Center (TMC), and temporary traffic signals for multiple maintenance and protection of traffic stages, as well as ITS devices consisting of: closed circuit television cameras (CCTV) to monitor traffic operations and Bluetooth travel time readers that read Bluetooth media.
