Intelligent Speed Adaptation (ISA) will be tested by Transport for London (TfL) during a six month period starting in the summer of 2009. As part of this trial, ISA will be installed in a London bus, a taxi and 20 TfL vehicles.

The technology will utilise satellite tracking and digital maps. Two modes will be available, an advisory mode and an automatic mode. An advisory mode simply tells the driver whether he is complying with the speed limit. The automatic mode will reduce the speed of the car to match the speed limit if the driver fails to do so, although this can be over ridden. There is also the option to prevent the vehicle from accelerating to a speed above the speed limit.

The whole of the London area inside the M25 motorway has been mapped. ISA will benefit from a digital speed limit map of London developed by TfL earlier in 2009. The trial will be concentrated on researching driver behaviour, effect of driving on emissions and journey times. Results of the trial will be published in spring 2010, when the technology will be made available to other organisations.

Southwark Council has expressed an interest in fitting ISA to more than 300 of its vehicles.

Objectives

The trial will monitor driver behaviour, journey times and the effect that driving within the speed limit has on vehicle emissions.

ISA uses the digital speed limit map of London which TfL launched on 29 January 2009. This is the first time all of London's speed limits have been mapped accurately with regular updates.

Other GPS device manufacturers are being encouraged to take advantage of this resource which could help to improve road safety in the Capital by introducing a speed limit display and warning in their satellite products.

It is estimated that if two thirds of London drivers use the ISA system, the number of road casualties in the Capital could be reduced by 10 per cent.

Results

Advisory ISA

This system takes the speed limit and displays the information to the driver via a dashboard unit. It is similar to the functionality found in many commercial satellite navigation devices (Garmin, TomTom etc). Advisory ISA brings the speed limit into the cabin of the vehicle and means that the speed limit is always available to the driver. Advisory ISA systems can also alert the driver when they exceed the speed limit for a given road.

Voluntary ISA

This system helps the driver by making it difficult to accidently accelerate beyond the speed limit. The units are intended to be small enough to fit within an engine bay or in the foot-well of a vehicle without being noticed. The Voluntary ISA we are investigating does not have the ability to apply any form of braking and will not impact acceleration up to the speed limit.

A beta Advisory ISA system is now available for public download, including source code released under the GNU license.

Voluntary ISAs will continue to be developed and further information on registering users' interest for trials of this technology will be made available at a later date. TfL intend to make these units available for Transport for London vehicles first and then may extend the trial to buses and taxis.

Applications and equipment

Applications tested

Advisory ISA and Voluntary ISA.

The intelligent technology enables drivers to select an option where acceleration is stopped automatically at the speed limit specific to any road in London within the M25 area.

Vehicle

A London bus will be fitted with ISA.

The TfL Road Safety Unit is also keen to trial the technology in a licensed taxi, alongside 20 TfL vehicles driven by road engineers, traffic managers and highway inspectors.
