TRAFFIC MANAGEMENT SYSTEMS WITH ADDITIONAL UP-LINK FROM IN-VEHICLE DATA

The concept of the Universal Traffic Management Systems (UTMS) designed in 1993 under the initiative of the National Police Agency is now at an actual deployment stage. Various UTMS-based systems have started operation in many areas all over Japan. The first half of this paper presents an example of communication line sharing among terminals of a traffic control center. This was achieved by introducing a front-end processor which integrated the functions of two UTMS subsystems (ITCS, Integrated Traffic Control Systems, and AMIS, Advanced Mobile Information Systems). The effect brought about by the introduced unit is also verified. The latter half of the paper presents several suggestions on measures for improving signal control systems by using up-link data from in-vehicle units.
