What is ITS (1)
The term intelligent transportation system (ITS) refers to efforts to add information and communications technology to transport infrastructure and vehicles to improve safety and reduce vehicle wear, transportation times, and fuel consumption.
What is ITS (2)
Intelligent transportation systems (ITS) encompass a broad range of wireless and wire line communications-based information and electronics technologies.
ITS are comprised of existing and new technologies, including information processing, sensors, communications, control, and electronics.
Why ITS? (1)
ITS answers to many of transportation problems.
ITS is used to improve safety and reduce vehicle wear, transportation times, and fuel consumption through the use of advanced information and communications technologies.
Combining those technologies in innovative ways and integrating them into our multimodal transportation system will save lives, time, and resources.
Why ITS? (2)
If using ITS, the early stages of a traffic bottleneck situation can be detected, and traffic can be directed to other routes and to provide faster and more efficient routes for travelers.
New technologies can response to occurrences of traffic problems in real time, and therefore, the problems can be solved before they develop into serious traffic jams.
How to ITS
ITS vary in technologies applied from a such car navigation to parking guidance and information systems.
Some of the constituent technologies for ITS:Wireless CommunicationComputational technologiesFloating car data/floating cellular dataSensing technologiesInductive loop detectionVideo vehicle detection
Briefly the use of the Technologies (1)
Wireless Communication:Short-range communications (less than
500 yards), it uses IEEE 802.11 protocols.Longer range: WiMax (IEEE 802.16), GSM,
or 3G.
Computational technologies: Embed microprocessor to the vehicle, in
order to implement such artificial intelligence, and ubiquitous computing.
Briefly the use of the Technologies (2)
Floating car data/floating cellular data: Using mobile phone network to track
vehicles move.
Sensing technologies:Infrastructure sensors devices are
installed or embedded on the road, or surrounding the road.
Briefly the use of the Technologies (3)
Inductive loop detection:The terms Inductive loop describe an
electromagnetic communication- and detection system, relying on the fact that a moving magnet will induce a electrical current in a nearby conducting wire.
Loops can be placed in a single lane or across multiple lanes to estimate the speed, length, and weight of vehicles.
Briefly the use of the Technologies (4)
Video vehicle detectionUses video cameras in automatic number
plate recognition (ANPR: to read the license plates on vehicles)
The typical output is lane-by-lane vehicle speeds, counts, and lane occupancy readings.
Some systems provide additional outputs including gap, headway, stopped-vehicle detection, and wrong-way vehicle alarms.
