Intelligent transport system can be defined as the technology applied to transport infrastructure (Road networks, traffic and transit systems) to improve the safety, convenience and productivity of personnel and the already available infrastructure.

Objectives of ITS

Importance of ITS

What ITS does differently?

ITS infrastructure is composed of many systems that work together to perform integrated functions. ITS infrastructure includes the following systems:

1. Traffic signal control systems
2. Freeway management systems
3. Transit management systems
4. Regional Multi-Modal traveler information system
5. Emergency management systems
6. Electronic toll collection system
7. Incident management program
8. Railroad grade crossing warning system
9. Electronic fare payment system

The National ITS Architecture provides a framework for planning, programming, and implementing intelligent transportation systems. The architecture framework is comprised of two technical layers, a Transportation Layer and a Communication Layer, which must operate in the context of an Institutional Layer. .. [Read More]

Traffic Management Centers

The objective of Advanced Traffic Management Systems is to maintain the smooth flow of traffic, improve user safety and reduce environmental emissions on all roads in the network. These systems typically use a combination of technologies that count vehicles, measure speed, and/or categorize motor vehicles to provide information to computers.

The basic principles of surveying have changed little over the ages, but the tools used by surveyors have evolved tremendously. Engineering, especial civil engineering depends heavily on surveyors. When ever there are roads, railways, reservoir, dams, retaining walls, bridges, or residential area to be built, surveyors are involved.... [Read More]

Features/Advantages

Combination of two or more simple circular curves of different radius having their curvature in the same direction. Essentially, a compound curve consists of two curves that are joined at a point of tangency and are located on the same side of a common tangent. [Read More]
