Traffic safety and forecasts

Since end of the 60's I have been interested in traffic safety topics. At that time well over 1000 people were killed every year, and yet there were a lot less cars in the traffic at that time. How could that come? Were all drivers crazy or did they not learn anything before they got their driver's licence?

On this site you will learn about a model that explains why the number of people killed in the traffic fluctuates but generally becomes lower by time despite the fact that the number of cars is increasing from year to year.

There are basically two main factors to consider:

A) The accumulation of driving experience over time
B) The increasing fraction of roads having separate driving fields

Hope you will enjoy the ride,
