| Summary | Both the Ministry of Transportation and Communications and the Institute of Transportation are actively carrying out research on communications architecture in order to answer the demands of the next generation of communications architecture and at the same time study how to adapt the different types of communications networks and their different NTCIP criteria so as to ensure that the formulated modules of the ITS system have “mutual operability” and “mutual replace-ability” during the period of operation. The related project results include (1) references to the requirements of both international and domestic criteria in order to draft and define a catalogue and collection of reference data for Taiwan’s urban area ATMS, APTS and ATIS applications, (2) quantitative analysis of communications protocol for the transportation detector system, (3) formulation of communications protocol and mechanisms which need to cross modules of transportation management and harmonize with the operations as well as the study of communications protocol and mechanisms for public bus priority signaling, (4) simulation and system testing of the movement and control of public bus priority signaling. From the urban traffic control practice perspective and based on the outcome of 2007 project, this research reviews national "urban traffic control protocol version 3.0", and adds more control protocols for changeable message sign (CMS) and CCTV devices. For the CMS device, control protocols for full-color LED and regional message management were added, and several new control protocols for CCTV devices were also included. A testing environment using standardized urban traffic control software is used to verify the feasibility of these new protocols. Communication response time and signal timing generation were also investigated and developed under this environment. Benefits of the research include (1) generation of a new version of urban control protocols to fulfill the future need of traffic control, and (2) support for the development national project “Intelligent Traffic Control Systems”. These outcomes can also be referred to by each city government in its future system development. |
