ISA – are we already at the
deployment stage?
Harri Peltola
Introduction – my ISA
Intelligent Speed Adaptation has a great safety potential Three levels of intervention have bee mentioned
• Advisory, Voluntary and Mandatory
In addition to these three levels, a fourth level - recording ISA - has been introduced and piloted in Finland
Feedback given to the driver periodically, not online • not as vulnerable to errors
• motivates concentration to the strategic level Recording driving behaviour will also enable the
collection and use of other traffic safety related indicators – measuring Naturalistic Driving
Recording ISA
Recording ISA system (SPEEDAUDIT+)
GPS for detection of location and speed and modem for sending the collected data to server
Other sensors like 3-D acceleration measurements Feedback reports generated by need using internet

Why recording ISA?
To motivate drivers towards a more moderate driving behaviour:
easy to accept, quick adoption and no legal problems
quality assurance system for transport companies and their customers
a monitoring system for speed offenders -as ALCOLOCK guiding novel drivers towards moderate driving behaviour (two phase driving licence)
saves lives as well as energy and environment
EXAMPLE OF USE - traffic planning

The effects of feedback?
During March - May 2003 the management of the taxi company has given feedback regarding too high speeds to 13 drivers.
6 of the drivers soon quitted driving in that company
4 of the drivers seem to obey speed limits better after feedback 1 driver seems to drive using as high speeds as before feedback 2 drivers have not driven with the car having measuring equipment
General feedback has been given also. It seems that even other drivers than those given personal feedback have been driving avoiding
Driving style - Speeding and feedback
The results suggest that personal feedback is needed at least when there are economic motivations for
speeding.
There were implications that repeated periodic feedback is needed.
The feedback needs to be concretised. "You often drive too fast" causes just explanations. "You drove XX %
faster than the average (company) driver in the city centre" and "you drove xx km/h through this specific intersection" makes the driver think.
Possibilities for exploitation
Part of driver training process
For monitoring special groups like speed limit offenders New models for motor insurances - the background
information (exposure and driving behaviour) A part of quality control system
