Abstract
The role of traffic calming schemes in urban network management is mainly to
minimize the undesirable effect of traffic in residential areas; in this context
accident reduction can be a realistic objective. Several studies, indeed, inform us
that traffic calming is a major part of the treatments available to reduce road
accidents in urban areas. Paradoxically the increase of the accident rate per
kilometre travelled has been observed in the urban context as result of the wellknown
accident migration phenomenon. In connection to these considerations,
the effectiveness of traffic calming measures on road safety is discussed in this
paper. Then, after a synthetic exposition of the conceptual formulation and the
potential of the meta-analysis method in detecting the true safety effect of traffic
calming measures, the paper also considers the role of road network planning
and the characteristics of the urban network that have to be consistent with the
traffic calming objectives. Lastly, a methodological framework to follow for the
implementation of traffic calming schemes in residential areas, from the planning
level to the road design level, is proposed.
Keywords: road safety, traffic calming scheme, meta-analysis.
1 Introduction
Strategies targeted to improve road safety follow in general two different aims: i)
reducing the severity of the consequences of risky behaviours by the installation
of devices useful to contain driver and passenger damage when collision occurs;
ii) making the consequences of risky behaviour more severe by the installation of
