Abstract: A traffic intersection control system or intelligent intersection that analyzes in real time existing traffic flow at intersections to determine whether turn lanes need to be added, lengthened, or done away with, if the lane geometry needs to be modified, and if the time duration of the signals needs to be shortened or lengthened. Conventional, painted, pavement markings are replaced with intelligent pavement markers (IPMs). The IPMs display an intense white or yellow light (e.g., an LED) or can be switched off. Overhead, electronic, lane usage signs alert drivers as to which lanes are through lanes, which lanes are for on-coming traffic, and which lanes are turn lanes. The intersection controller analyzes data about current traffic flow and historical data to determine the most efficient intersection configuration and signal timing for a set time period. If necessary, the controller reconfigures the intersection by controlling the IPMs and overhead lane usage signs using communications equipment.
