Identifying obstacles to traffic management using third-party, GPS-based data

Traffic monitoring is a key function for traffic management centers (TMCs), which are generally responsible for high-order facilities such as freeways and limited access facilities. The cost of existing surveillance technology is extremely high because of the extensive infrastructure needs involved. These devices are effective when they are operational, but studies suggest high rates of failing sensors for large state-wide networks. Additionally, the geographic coverage of these systems is limited to those infrastructure requirements.
