WisDOT is building a fleet of temporary ITS devices (e.g., cameras, DMS) by purchasing devices for construction projects and reusing them on future projects. WisDOT supplies the devices to the construction contractor for deployment and operation during construction.
Traffic Management
RReused Tolling Structures
In Rhode Island, tolling operations have transitioned to a contractor. Rhode Island DOT has reused tolling structures for other uses (e.g., counting traffic, speeds).
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.
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.
Floating Car Method Reduced with Arterial Probe Speed Data Use
ODOT has achieved savings (and is obtaining better data) for travel time studies and signal
timing contracts, as less time and effort is dedicated to the floating car method for these
studies.
Legacy Advanced Transportation Management System (ATMS) Replaced with Intelligent Roadway Information System (IRIS) Open Source ATMS Software
