Transit service reliability is important to both passengers and transit agencies. Slow and unreliable transit service may increase transit user costs in the short term and reduce transit mode share and ridership in the long term, which in turn may lead to higher levels of congestion, emissions, energy consumption, and car dependency in urban areas. In addition, bus travel time is important to schedulers because excessive variability forces schedulers to add excess slack or layover time to tra... Read More

Application of Interactive Video Sensing and Management for Pedestrian and Bicycle Safety Studies

As video data collection and storage technologies become ubiquitous and inexpensive, transportation agencies struggle to process and extract "intelligence" or useful information from growing libraries of archived video data. In some cases useful video is lost because agencies cannot justify the expensive staff time required to process it. This video information overload is caused by the inability of most transportation agencies to write customized video processing algorithms to extract va... Read More
