Traffic calming measures in new traffic environments and the use of ITS (English)
A literature survey has been conducted regarding international traffic calming measures that could have a potential use in Sweden and other Nordic countries. Focus has been on measures in new traffic environments and ITS (Intelligent Transport System) based solutions. Information has been obtained through searches in literature databases and on different homepages, as well as from contacts in networks. Initially, we describe common traffic calming measures used today in Swedish traffic environments. For example, different forms of vertical and horizontal measures, and different types of surfaces, road markings and paintings. In the case of existing ITS solutions, we mention speed reminder signs, variable message signs and Motorway Control System (MCS).
New kinds of physical measures that have most potential for use are e.g. modifications of speed bumps and the construction of small curves that enforce lower speed. Such curvatures can be used at entrances to communities or before roundabouts.
Different concepts of "shared space" (e.g. walking speed zones) are something that could be used more extensively, even at intersections and other locations in urban areas. In such cases, all traditional road equipment is removed and a synergy between different user groups is created, leading to lower speeds.
Different types of road markings and paintings can be used to visually narrow the road, but also in order to create an optical illusion that makes one feel as if the speed is high. However, such measures are not fully effective during winter conditions. Applications in 3D can also be used to create the illusion of obstacles in the roadway and result in reduced speeds. It is important to consider the overall picture and to combine various measures in a correct way. This report gives some examples on how to implement speed reduction measures in communities with thoroughfares. Furthermore, we give example on how strategic approaches and policy design may help to efficiently implement different kinds of traffic calming measures.
ITS-solutions, where a two-way communication between vehicles and between vehicles and the infrastructure is used, have gained momentum in Europe and internationally. Three possible systems that have not yet been introduced on the market are described. Most of the cooperative systems are still in a research and development phase. The potential of the systems is considered to be large, and this is also reflected in the extensive research and development investments in the area. Furthermore, ITS as a whole, i.e. cooperative systems as well as other ITS solutions is believed to have a great potential.
