Our traffic-monitoring application estimates travel time for different routes using real-time traffic flow information. It derives that information from probe vehicle speed on different road segments. Probe vehicles monitor the road environment through in-vehicle sensors. 1 Xiaowen Dai and her colleagues have determined that we can derive useful traffic flow information if 5 percent of vehicles act as probes. 2 This approach promises reduced infrastructure installation and maintenance costs
