Abstract
Technologies are described to provide control of traffic signals based at least in part on the presence of non-motorized users. In some examples, a system may include at least one sensor configured to autonomously acquire motorized user presence data at an intersection, and at least one sensor configured to autonomously acquire non-motorized user presence data at the intersection. The system may also include an agent configured to determine a motorized user queue length based on the motorized user presence data, determine a non-motorized user queue length based on the non-motorized user presence data, and control the traffic signals based at least in part on the non-motorized user queue length.
