Railroad crossings may cause unexpected blockages and considerable traffic delays, especially in urban areas. However, there is no practical system available to share potential crossing blockage information to the public. An unexpected blockage threatens first responders while they respond to emergencies. This research project has developed an Intelligent Crossing Assessment and Traffic Sharing System (i-CATSS) that can detect and predict highway-rail blockages at grade crossings and provide first responders with real-time information of traffic conditions at crossings.
