The purpose of the present study is to develop a method for following up changes in driver speeds on the main municipality streets in urban areas, and to report the results concerning driver speed levels and speed limit compliance after the first two years of measurement. The results show that in 2013 the average speed was 49.3 km/h. When broken down by speed limit, the average travel speed was 39.2 km/h for the 40 km/h speed limit, 46.9 km/h for the 50 km/h speed limit, and 54.9 km/h for the 60 km/h speed limit, and 61.9 km/h for the 70 km/h speed limit. No significant changes in travel speed occurred in comparison with 2012. There was a broad distribution between the speed levels for the various points within each speed limit; this is natural in urban areas, as there are many other factors in addition to the posted speed limit that will affect drivers' speed choices, such as intersection density, road width, and the presence of street parking and pavements. With respect to the proportion of violations, overall a total of 37 per cent of the traffic drove over the speed limit in 2013; that is, 63 per cent of drivers obeyed the speed limit. Speed limit compliance was worst on roads with a speed limit of 40 km/h, where only 53 per cent of the traffic obeyed the speed limit; 61 per cent obeyed the speed limit on 50 km/h roads, 69 per cent on 60 km/h roads, and 77 per cent on 70 km/h roads. Hence it is primarily speed limit compliance on roads with lower
