Converting Highway Advisory Radio (HAR) Signs to Inform Motorists of 511 Phone
PennDOT is no longer installing new HAR sites and is converting in-place HAR signs to inform motorists of conditions being reported on 511 phone. During the transition, PennDOT is reusing components from non-operational HAR devices to extend the life of other in-place devices.
Integrating Standard Work Zone Equipment Through its Advanced Traffic Management System (ATMS)
Standard work zone equipment is integrated with the ATMS system through several efforts including speed management (Variable Speed Limits (VSL) for both dynamic and static displays of speed limit), ramp metering (a pilot deployment within a work zone that can deploy both static and dynamic ramp metering), and traveler information (work zone travel time, use field detectors and/or probe data to provide queue related messaging, and Integrated Corridor Management).
Combined Situational Data Sources to Delineate When Incidents Truly Occurred
PennDOT had a need for better data aggregation and analysis to support decision making. In 2015, PennDOT started an initiative to audit the readily available DOT and vendor data resources that related to Transportation Systems Management and Operations (TSMO). PennDOT combined situational data sources to more accurately delineate when incidents truly occurred, how long it took them to be cleared, and what their overall impact on traffic was.
Arterial Probe Data has Improved Signal Prioritization
Arterial probe speed data for PennDOT has provided the ability to evaluate the impacts and benefits over a longer period of time to assist in signal prioritization.
