demonstrating the concepts of a new class of
road related services (such as those related
to traffic management and mobile electronic
payments) for both safety and convenience.

Research is required for modernization of
traffic management system. The highway traffic
management control (HTMC) system collects
data in real time, calculates current traffic status,
estimates future demand and processes the
data to extract the information required by the
roadway controller which, in turn, generates
commands for ramp metering, speed limit
distributions at various sections of the highway
as well as generates routing instructions
