The management of road traffic, the security perspective in particular, is expected to undergo a radical change in the next few years. The repressive methods used to secure the road traffic will be gradually abandoned in favour of methods that have more of a participatory nature. Equipment and devices used so far to manage the movement of vehicles will be phased out in favour of a more intelligent instrument worthy of development now reached by the technologies of information processing and communication.

It should be noted that efforts by car manufacturers in the field of security using advanced technologies have unfortunately not been accompanied by the least developed in the field of traffic and securing roads. The only ways are used to date the government to fight against the growing trend of road accidents are the means of repression. The decrease in accidents that could be proven by the use of these resources is often an illusion because the harm inflicted repression to users by their numbers could exceed the damage caused by accidents themselves (fines, withdrawal of driver's license, imprisonment, etc ...)

Rafiq system, developed by our office, is a system based primarily on information processing. It can be considered a forerunner in the revolution that will not fail to know very soon the future Highway Code. Consisting of simple electronic sensors and a computerized information processing, it can provide road users with information to adjust their behaviour to minimize the risk of accidents while providing the conduct as comfortable as possible.

The main information generated by this system includes :

• The small risk of occurrence of accidents ;
• The major risk of occurrence of accidents ;
• The ideal speed of movement (speed optimized according to the terms and condition of the road) ;
• The average number of overtaking manœuvres per kilometre ;
• The detection of any plugs that may block the way ;
• The stress experienced by drivers of vehicles ;
• The periodic chart (daily and weekly) of road traffic.

The information, including those cited above, are deemed useful to drivers can be transmitted either through postings on signs, or using other means offered by new technologies: Radio, GPS, wi -fi, etc. ...

It also helps integrate and process information relating to accidents in a country or region and to determine with precision the causes most recurring causing it. This helps to target actions to be taken as the most advanced possible to reduce their numbers and their frequency. This function of the system has the advantage of combining an intelligent two factors responsible for accidents, namely the Cause of the accident and the condition of its progress.

The system may finally be set to consider the regulations in each country or region and can adapt to different road types: single-lane, two-lane, highways ... etc. The sensors will be installed at distances ranging on average 20 to 40 km can be operated separately from each other or operate in a network to provide more details on the status of traffic.

The operation of this system requires the installation of sensors on average every 20 to 30 miles for motorways and all 10 to 20 km for other types of roads. Knowing that there are more than 125 thousand miles of highways and more than 9.3 million miles roads worldwide, the company that will handle the manufacture and distribution of this system will ensure that potential with the leading position in the field and for several decades.
