Overview
Objectives:
The aim of this study was to improve the understanding of the concept of self-explaining roads in urban areas by studying the relationship between speeds at a particular location, the speed limit and the road environment.
Methodology:
The relationship between actual speed levels, speed limit and traffic environment has been studied based on earlier speed measurements made by NTF (National Society for Road Safety) in 23 different cities and a total of 69 measuring points. In addition, traffic engineers from 73 different municipalities studied photos from 20 different locations and made an assessment of the speed limit at the site, so-called blind estimation.
