During the last three years a project called Intelligent Speed Adaption (ISA) has been running with the goal of informing the driver of the current speed limit on the roads of certain areas in Sweden. The ISA-system also warns the driver when exceeding the speed limit by a sound signal or vibrations in the accelerator. This R&D project by Columna is a part within the framework (VITSA) for the application of Stiftelsen Teknikdalen to prolong the ISA project. It is named ITR and aims to produce an intelligent aid to vehicles/drivers regarding adaptation to prevailing traffic regulations. ISA has set its scope to the task of informing the driver of a vehicle about current speed limitations. ITR evolves around the same generic technique to inform about other types of traffic regulations, such as the following:

The observance of the traffic regulations involves particular influence to traffic safety: 

• Obligation to stop 
• Obligation to yield 
• Pedestrian street 
• Turning ban/decree 
• Banned driving direction 
• Motor vehicles prohibited 
• Primary road/Motorway/Arterial road 
• Overtaking prohibited 
• Restricted length, width.

Information along the same lines as the above could potentially inform the driver at an appropriate time and with an appropriate approach. In this way many hazardous situations can be avoided where the driver, due to lack of attention, neglects to stop or to travel in a cautious manner or even in the wrong direction.

The observance of the following traffic regulations affects the environment:

• Restrictions regarding hazardous goods; 
• Restricted regarding idling motor.

The observance of the following traffic regulations has several different effects. These regulations will, until further notice, be classified as public information: 

• Stopping or parking restriction; 
• Permission to park certain hours with certain vehicles etc. 
• Information concerning road name and number; 
• Weight limits.
