The aim of the present study is to report the changes between the years 2014 and 2015 concerning driver speed levels and speed limit compliance on the main municipality streets
The year 2012 was the starting year for the measurement series, and in 2015 a third follow-up was performed. Only the main municipality streets with speed limits between 40 km/h and 70 km/h were included. The measurements were made during the month of September in 23 different municipalities in Sweden
The results show that in 2015 the space-mean-speed for all vehicles on the main municipality roads was 48 km/h. With respect to speed violations, overall, 64 per cent of drivers obeyed the speed limit 2015. The lowest speed limit compliance was found on roads with a speed limit of 40 km/h, where only 44 per cent of the traffic obeyed the speed limit; 66 per cent obeyed the speed limit on 50 km/h roads, 75 per cent on 60 km/h roads, and 72 per cent on 70 km/h roads.
In conclusion, the space-mean-speeds in urban areas are below the legal speed limit, but the lack of speed compliance remains a problem. Primarily, the speed limit compliance on roads with lower speed limits must be improved in order to reach the goal of 80 per cent compliance by 2020.
