The vehicular traffic is increasing tremendously in today's/this world,
simultaneously congestion also increases.
In order to prevent congestion, one option is to increase the capacity by
increasing the number of existing transportation system.
A second option is to develop alternatives that increase capacity by improving
the efficiency of the existing transportation system.
The later focuses on building fewer lane-miles, while investing in Intelligent
Transportation Systems (ITS) infrastructure.
The goals of ITS include the following:
- Enhance public safety;
- Reduce congestion;
- Improved access to travel and transit information;
- Generate cost savings to motor carriers, transit operators, toll
authorities, and government agencies; and
- Reduce detrimental environmental impacts.
Intelligence requires information, and information requires data, which is
generated by surveillance.
ITS include sensor, communication, and traffic control technologies.
These technologies assist states, cities, and towns nationwide, meeting the
increasing demands on surface transportation system.
Vehicle detection and surveillance technologies are an integral part of ITS,
since they gather all or part of the data that is used in ITS.
So a wide range of data is required for ITS to manage:
- Volume Count
- Vehicle Classification
- Vehicle Occupancy
- Travel Time
- Delay
