Overview of Smart Vehicle.
• EDR .
- used in vehicles to register all important parameters such as velocity, acceleration, etc. especially during abnormal situations, such as accidents.
- This data is used for reconstruction.
• Forward radar.
- Used to detect any forward obstacles as far as 200 meters .
• Positioning System.
- Used to locate vehicles.
- Accuracy can be improved by knowledge of road topology.
- Computing platform-.
- Inputs from various components is used to generate useful information.
Vehicular Ad-hoc Networks (VANET).
• A Vehicular Ad-Hoc Network, or VANET is a technology that uses moving vehicles as nodes in a network to create a mobile network. VANET turns every participating vehicle into a wireless router or node, allowing vehicles approximately 100 to 300 meters of each other to connect and, in turn, create a network with a wide range. .
• As vehicles fall out of the signal range and drop out of the network, other vehicles can join in, connecting vehicles to one another so that a mobile Internet is created.
