The Virginia Department of Transportation’s Northwestern Regional Operations (NWRO) Region implemented an Automated Traffic Signal Performance Measure (ATSPM) reporting system for intersections along the US 29 corridor near Charlottesville, VA. When a new version of the software was released in 2016 by the Utah Department of Transportation (UDOT) in coordination with the Federal Highway Administration (FHWA), VDOT wanted to upgrade, troubleshoot, and debug their existing system.
Kittelson provided on-site and remote support to upgrade VDOT’s ATSPM software to the latest version, and is continuing to troubleshoot/debug errors related to the specific equipment being used on the US 29 corridor (e.g., controller firmware, detection setup). Kittelson is also performing routine performance evaluations using the ATSPM reports to identify potential operational improvements, mis-programmed signal timing parameters, and malfunctioning equipment.
Signal Performance Measures: Keeping VDOT in the Know
The ATSPM system has been upgraded and validated. VDOT has demonstrated substantial benefits through before/after analyses, and is in the process of investigating further improvements identified using the ATSPM reports.
