THE EFFECTS OF TRAFFIC CALMING MEASURES ON THE DYNAMICS OF A VEHICLE
TIEN RAKENTEELLISTEN HIDASTIMIEN VAIKUTUS AJODYNAMIIKKAAN
The aim of traffic calming devices is to decrease speeds used by drivers to the degree that they do not exceed acceptable speed levels. The slowing down effect of the calming devices is based on their detrimental effect on the driving comfort when the speed of the vehicle exceeds the desired level. Single calming devices or devices placed too far apart are only effective at one point. The best traffic calming solution is one that produces speeds over the entire stretch of road. Constant speed also decreases emissions caused by repeated deceleration and acceleration. Traffic calming devices are road humps, narrowings and horizontal deflections (chicanes). Roundabouts can also be used for the purpose. This study focuses on the effects of structural traffic calming devices on the dynamics of vehicles.Dynamic properties are speed, acceleration and deceleration. This study consists of a literature section and a field study section. The methods employed were radar, traffic impedance analysis and recording on video. Field measurements were made at twelve locations in various parts of Finland.
