Traffic priority to encourage multimodal transportation

Giving high priority to public transportation without interrupting the general traffic flow has been a major challenge for conventional traffic control software in the past. The Yunex Traffic SEPAC software has a powerful traffic signal priority mechanism that enables mobility, safety and a better environment to improve the quality of life in cities by enhancing performance of traffic signal control for a number of transportation channels such as Light Rail Transit (LRT) and Bus Rapid Transit (BRT) with minimal impact on pedestrian and vehicle traffic.

Modes of Operation

SEPAC‘s traffic capabilities include five modes of operation that allow for Time of Day (TOD) operations, week plans, time of year or holiday plans which include coordination, free and flash functions.
