Unfortunately, travel time cannot be directly measured by certain new detection technologies, such as Automatic Vehicle Identification (AVI) or Automatic Vehicle Location (AVL) systems, these new technologies are not widely deployed and are much more costly than loop detectors. Finding an accurate way to estimate travel time using loop detector data offers great economic benefits. this project examined the development of improved arterial travel time models. In the project's first pahse, researchers reviewed existing travel time databases. the project's second phase will seek to develop and evaluate new travel time estimation models
