Intelligent Speed Adaptation

•GPS is based on a network of satellites that constantly transmit radio signals.

•GPS receivers pick up these transmissions and compare the signals from several satellites in order to pinpoint the receiver’s location to within a few meters.

•Four satellites is the minimum number of satellites required to determine a precise three-dimensional position.

GPS(Global Positioning System )

Roadside radio beacons, or bollards, work by transmitting data to a receiver in the car.

The beacons constantly transmit data that the car-mounted receiver picks up as it passes each beacon.

The use of radio beacons is common when ISA systems are used to control vehicle speeds in off road situations, such as factory sites, logistics and storage centres, etc.

Radio Beacons

This technology has been focused solely on recognizing speed signs.

The reflective "cats eyes" that divide lanes could possibly be used.

The system would use the speed limit from the last sign passed until it detects and recognizes a speed sign with a different limit. If speed signs are not present, the system does not function.

Optical Recognition Systems

Dead reckoning (DR) uses a mechanical system linked to the vehicle’s driving assembly in order to predict the path taken by the vehicle.

By measuring the rotation of the road wheels over time, a fairly precise estimation of the vehicle’s speed and distance traveled can be made. Dead reckoning requires the vehicle to begin at a known, fixed point.

Then, by combining speed and distance data with factors such as the angle of the steering wheel and feedback from specialized sensors (e.g., accelerometers, flux gate compass, gyroscope) it can plot the path taken by the vehicle.

ACCIDENT AVOIDANCE SYSTEM

In an emergency, many people do not depress the brake pedal hard enough. EBA senses an emergency braking situation and helps the driver to reduce speed in the shortest distance possible.

Emergency Brake Assist

TC makes driving on twisty and slippery road conditions safer, by using sensors to detect whether any of the wheels is losing traction.

TC has the ability to cut power in a flash, helping the car to regain its grip. If in any case the car shows a tendency to skid the system automatically slows the particular wheels to help maintain control.

Traction Control System

With ABS you can brake as hard as you can and steer yourself to safety without the fear of wheels locking up and skidding.

Anti-Lock Braking System

 EBD makes sure that the braking forces of the car are distributed between the front and the rear brakes in order to optimize braking efficiency.

Electronic Brakeforce Distribution

Using cameras set just below the outer rear view mirrors the BSIS tell you if there is any vehicle in your blind spot.

Blind Spot Information System

NIGHT VISION• Driving during the night becomes safe than ever with the night vision where one can see clearly on the control display even in pitch black. Thanks to infra red technology.

BENEFITS • Strategic thinking in traffic safety acknowledges that Intelligent Transportation Systems (ITS), and in-vehicle technologies in particular, hold promise as safety measures to counter the risk of road crashes and the trauma arising from crashes.

• Real and perceived benefits of ISA are a reduction of accident risks [citation needed] and reductions of noise[citation needed] and exhaust emissions.

ISA technologies do work, are robust and reliable.

They are technically simple, much simpler than other automatic devices such as collision avoidance systems. Delivering and maintaining the relevant map data for ISA is not a problem either, provided that legislation is there to ensure action is undertaken in a harmonized way

Having cleared the road of these obstacles we can now drive forward quickly the implementation process – the only time increased speed will enhance road safety.
