- Predictive Traffic Lights

Traffic flow can be significantly improved with predictive and more responsive traffic lights. Traffic backups, both on city streets and highways, often result from backups at lights. While the light patterns may be staticly optimized for average traffic flow, unneccessary waiting and stops occur when a system isn’t sensing actual traffic. By eliminating extra stops and better balancing wait times, road capacity can be greatly increased. That lowers travel time, number of cars on the road, impact to neighborhoods, dangerous congestion, and fuel use and polution.

Although some lights in Sunnyvale have traffic lane sensors to help trigger light changes, there is a lot of room to greatly improve traffic flow by more intelligent light management. A better system can be put in place that has a model of city traffic patterns, sensors far from intersections, and features to integrate with a Bus Rapid Transit system. Some implementation opportunities are potentially very inexpensive. For instance, a Sunnyvale SunTran mobile app used by enough residents could provide traffic flow sensing information with no additional physical investment. Investments in traffic flow cameras and other sensors, including security cameras, could be leveraged to provide additional information to an autmoated traffic sensing system.
