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

Do TODs Make a Difference?

Arthur C. Nelson Jenny Liu , Reid Ewing
The United States is moving into a new era of metropolitan development and form. The demographic, economic and finance drivers that made America a suburban nation may have run their course. America will see a shift toward infill and redevelopment. Facilitating this will be fixed-guideway transit systems and the transit oriented developments (TODs) they serve. In this report, we present research that measures the outcomes of TOD areas in relation to their metropolitan area controls with respect… Read More
