Electronic Handbook on Communications for Traffic Control and ITS Applications.PC-Based Visual and Interactive Handbook for ITS (IVHS) Communications Functions

摘要

A comprehensive reference handbook is developed to treat communications topicsthat are relevant to traffic control operations, freeway management and intelligent transportation systems (ITS) development. The subjects include basic communication principles, the requirements of communication systems for traffic control, communications technologies for traffic control systems, and the selection of communications architectures and technologies. An electronic version of the handbook is implemented as an HTML document. This allows the user to read and interact with the handbook using an Intenet browser, such as the Netscape Communicator and the Microsoft Explorer. In particular, on-line calculators are implemented using the Java programming language and integrated with the electronic handbook. The calculations pertain to (1) communication bandwidth requirements for traffic control operations, (2) transmission line parameters, and (3) antenna parameters.
