46 Practices on Acquiring Proprietary Data for Transportation Applications • Guarantee data accuracy of ± 4 mph; • Provide access to the analytics tools, including region explorer, massive raw data downloader, congestion scan, trend maps, performance charts, performance summaries, bottleneck rankings, and user delay cost analysis; • Provide data in XML format and at an interval that would let Ohio DOT's traffic information systems produce accurate and timely traffic information; and • Make real-time speed data available to the agency's central control system through a vendor's server. The RFP stated that Ohio DOT intended to use real-time data for transportation purposes, including the operation of freeway management systems, the OHGO app and BuckeyeTraffic.org (both for color-coded speed range maps)

Case Examples 47 Use Cases Speed data The main use cases for the real-time speed data are DMS, 511 services, and incident recovery monitoring. The historical speed data set has been used in a wide range of applications, such as before-and-after studies and calibration and validation of statewide and MPO travel-demand models.

Case Examples 51 Peer Advice Obtaining probe data to monitor traffic conditions is a much less-expensive option than installing sensors on roadways in areas under travel advisory during freeway construction. Agencies can modify their probe data coverage in the future if needs change; whereas, permanent sensor installations do not afford this flexibility.

52 Practices on Acquiring Proprietary Data for Transportation Applications Planned uses of the data included providing traveler information to the public, obtaining and archiving historical traffic data to inform agency planning, tracking historical changes in traffic volumes, and using traffic data to report performance and support the operation of freeways and the arterial system. In addition to describing the Arizona DOT's data needs, the RFP stipulated that the winning contractors shall be available to all jurisdictions within the state of Arizona that request trafficdata services and that utilize federal, state, city, county, or any other jurisdictional funding for such requests.

Case Examples 53 both the agency and taxpayers would benefit from making data acquisition more efficient and giving multiple jurisdictions access to data. Strong partnerships between the Arizona DOT and MPOs and other local agencies have also facilitated adoption of the on-call contracting strategy.

Analysis of probe-speed data by the KTC–KYTC team is being used to develop comprehensive sets of congestion measures for statewide network screening and project selection.
