Performance Envelope of Cellular-Based Technology for Incident Detection and Traffic Management

Cellular-based probe technologies (Cellular Floating Car Data, CFCD) can be used to support both road traffic management activities and traveler information systems. However, traffic information that can be derived from these systems is different than traffic information derived from road sensors (such as inductive loops). Furthermore, different cellular detection systems provide different types of data, since their core method and technology differ significantly. Some utilize statistical analysis and predictions which have at least a 30-40 minute delay in incident detection, while others provide only a short 2-5 minute delay in comparison with road sensors. Smart planning can use the benefits of each technology and generate optimal value for budget.
