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.

Revised Process for Speed Studies Using Arterial Probe Data
ODOT revised their speed limit study tool (due to the pandemic) and is using it to understand actual speeds in the field from arterial probe data rather than physically driving to sites to conduct speed studies.
Probe Data to Identify Systems to be Retimed
NCDOT leverages probe data to improve the ability to identify the systems that need to be retimed. Availability of data more frequently improves monitoring and the identification of inefficiencies. This provides a mechanism to aggregate system performance metrics to near-real-time identification of inefficient systems, moving towards true active management on arterial networks.
Probe Data Providing Data-Driven Approach to Identify Congestion Reduction Projects
Use of arterial probe speed data has provided NCDOT with a data-driven approach for selecting which corridors to retime each year as opposed to previously a very subjective process.
Freeway Closure Plans for Full Road Closures
MnDOT developed 525 freeway closures for the metro freeway system to be used during major incidents to help coordinate incident response by MnDOT and determine traffic control needs for a full road closure.
Updated Signal Timing and Traffic Management Center (TMC) Control to Manage Pedestrians at an Intersection, Reducing Officers Needed
A new GDOT Intelligent Transportation System (ITS) deployment included programming for time-of-day pedestrian scrambles designed for all-way pedestrian crossings during heavy volume times that could be controlled directly from the GDOT TMC. In the past, most intersections required at least six officers to manage the crowd and vehicles; now an intersection can be managed by two officers.
