Using Vehicle Probe Data to Evaluate Speed Limits on Texas Highways

The research team will explore if there are refinements that could be made to the recently developed protocol for using third party data in generating suggested speed limits. The suggested speed limit probe data (SSL-Probe) protocol was developed to allow Texas Department of Transportation (TxDOT) districts to be more pro-active and responsive with their speed zone program. The protocol also provides a much safer method of collecting speed data, especially on high-speed and controlled access highways.
