Development of Intelligent Multimodal Traffic Monitoring using Radar Sensor at Intersections

Siyang Cao Yao-Jan Wu
Intelligent Transportation Systems (ITS) need traffic data to run smoothly. At intersections, where there is the greatest potential for conflicts between road users, being able to reliably and intelligently monitor the different modes of traffic is crucial. The Federal Highway Administration (FHWA) estimates that more than 50 percent of the combined total of fatal and injury crashes occur at or near intersections. For pedestrians the intersection is a particularly dangerous place: the City… Read More

FHWA Guidebook for Measuring Multimodal Network Connectivity

Joe Broach Jennifer Dill , Kelly Clifton
In 2018 the Federal Highway Administration issued a new guide, Measuring Multimodal Network Connectivity. TREC researchers contributed to the guidebook in partnership with Alta Planning + Design and ICF. The guide provides information on incorporating connectivity measures into state, metropolitan, and local transportation planning processes. It outlines five core components of pedestrian and bicycle network connectivity: network completeness, network density, route directness, access to… Read More
