Lesson Learned from the Effect of Traffic Calming in a Downtown District of Szczecin, Poland for Congested Urban Center | Chapter 1 | Science and Technology - Recent Updates and Future Prospects Vol. 2

 

There has been a lot of research to overcome traffic jams, but the application of traffic calming has been very important since the past in Europe and the USA. The aim of this research is to carry out physical quantification based on impact analysis within the urban centre. Three street sections starting and ending with different intersection types were chosen to examine the synergy of the applied traffic calming measures. The numbers and speeds of vehicles were measured in three day-long continuous surveys. As it was expected, the amount of speed reduction depended on the hourly traffic volume on a one-way street and various other traffic engineering aspects. The obtained results may be used to modify the existing speed profile models and can guide traffic engineers in choosing the most effective traffic calming measures. In the near future, i.e., after the completion of the upgrading of all the streets in the analysed block, the authors plan to repeat the traffic volume and speed reduction measurements with the purpose of supplementing the existing zone 30 km/h speed profiles, if appropriate and required.

Effect of the Coincidence of Interdisciplinary Actions on the Expected Speed Reduction | Chapter 2 | New Approaches in Engineering Research Vol. 4

 In an era of increasing traffic volumes, traffic calming issues appear to be fundamental challenges that link a number of related, but on the surface independent, issues involving various social groups. The fundamental issue in smaller towns and villages is ensuring traffic safety on the sections of through roads that cross their territory. Domestic and international road design guidelines recommend incorporating traffic calming devices where traffic enters a built-up area and in the center zone to reduce speeds along a road cutting through a village. Constructing traffic calming devices in transition zones is one solution. The second issue is to implement traffic calming measures in congested areas. It appears that the task should be simple and should fall under the purview of road workers. However, research and analysis into the effectiveness of traffic calming devices show that the best effect is obtained by coordinating the interdisciplinary efforts of road builders, local governments, urban planners, and many other specialists. A clear case in support of the above thesis is an example of coexisting traffic calming measures implemented in the village of Wrzosowo, Poland. The mere installation of traffic calming devices does not guarantee that the desired results will be obtained. of a traffic speed survey conducted in Poland to assess the speed reduction achieved on a section of a regional road passing through a village Speed measurements were taken three times: before the existing road was rebuilt, after the reconstruction, and after the implementation of all traffic calming elements designed by road builders and urban planners in charge of shaping the road's surroundings. The analysis of the results revealed that chicanes built in transition zones to villages, when used as the sole measure, did not provide a reduction in speed. a stream of traffic cutting through the village It was only by chance that the application of traffic calming devices and elements of road vicinity development resulted in the anticipated traffic speed reduction, thereby improving environmental conditions and local road safety. The conclusions drawn from the analysis confirm that the location of chicanes, the use of central reservation strips, and traffic barriers must be closely related to the elements of development present in the vicinity of the road, as well as the location of road signs informing motorists that they have entered a built-up area.
