Safety on highways is a major concern for many international players because many lives are lost and property damaged due to accidents. As an effort to curb the issue with road safety, the project vision zero was established. For the purpose of this article, the abbreviation VZ will be used. VZ is a road traffic safety project that is participated in by several nations. The aim is to achieve a highway system in which there are no serious injuries or fatalities as a result of road traffic.
Various aspects of this initiative are governed by many principles. One of the aspects governed is construction of highways. Safety, ethics, mechanisms for change, and responsibility are the four major principles. Human safety is prioritized under the safety principle more than all other goals of road traffic systems.
The responsibility principle emphasizes shared responsibility between regulators and providers of road traffic systems. Under the safety principle, human fallibility must be taken into consideration and the opportunities for error must be minimized. Also, in cases errors occur, the amount of harm done must also be minimized. The mechanism for change emphasizes the need to change in order to achieve the goal of zero fatalities due to traffic accidents.
In order to achieve the objectives of the project, certain limits have been suggested on speed. Suggested speed limits are based on the limits of human being and vehicles. For example, if an accident occurs in which a car knocks a person, if the car is well designed, the person can effectively stand a hit at a speed of 30 km/h. Frontal impact between cars on the other hand can be withstood to speeds not more than 70 km/h in well-designed cars. For side impact, one will be safe in a well-designed vehicle at up to 50 km/h.
Pedestrian and vehicular traffic need to be separated in situations where vehicles must move at high speeds. Otherwise, it is advisable to constrain the speeds of all vehicles moving through urban setting to less than 30 km/h. According to recommendations of the initiative, speeds of over 100 km/h may be achieved if the design of the road does not permit side or frontal impact.
There are several ways of ensuring that roads lack any possibility of side or frontal impacts. The first method is by constructing crash barriers to separate traffic in different directions from each other. Another way is by prohibiting slower of more vulnerable road users from using sections of roads where only high-speed vehicles are allowed to move. Additional methods are to ensure limited access and to use grade separation.
The adoption of VZ has varied a lot among countries. Whereas some countries have adopted the initiative on all their roads, some have limited the adoption to specific roads or areas. For instance, Canada first adopted the initiative in Edmonton City in 2015 before other cities followed suit later.
The level of impact experienced from this project is highest in developed states. There has been a significant fall in the number of fatalities. The same is not true in poor countries where adoption has been slow and non-uniform while fatalities rise yearly. Achieving zero fatalities globally is a goal that is still far from recognition, but it is achievable.
