Traffic calming measures are implemented increasingly frequently to improve safety of traffic in urban areas. Speed is one of the parameters having a bearing on the safety of traffic and, as such, it is important to assess the effect of the design measures on the operating speeds of vehicles. This paper investigates the efficiency of traffic safety measures implemented in city centre areas. The research site was a street where alterations of vehicular and pedestrian traffic management and parking arrangements had ...

There are a number of traffic calming measures that can be employed to protect vulnerable road users (VRU). Traffic calming is of critical importance in small towns and villages crossed by regional roads where it is necessary to resolve a number of conflicting traffic-related interests on stretch of a road that is just 500 m to 1,200 m long. Pedestrian refuges are one of the most common measures used to protect vulnerable road users. Considering the statutory speed limit of 50 km/h applying in daytime to all roads...

A quick development of motoring poses, particularly in cities, a number of transportation challenges involving traffic flow and maintaining its safety. To ensure road safety in streets facing transportation challenges, different systems of traffic calming have been successively introduced aiming at improvement of living and safety conditions. Suburban districts and housing estates are having their traffic arrangement plans changed. Traffic calming zones (e.g. Woonerven, stille veje, zones 30, home zones) are intro...

Environmental compensation aimed at keeping bat flight paths open is a major environmental protection issue. The small mammals play a very important role in eliminating pests and insects, pollination and seed dispersal. New roads often sever the continuity of bat migration routes. Not only do bats have traditional migration routes, but also their winter habitats rarely change. Given the above, many countries use different solutions of sustainable civil engineering, geared towards maintaining free passage for bats ...
