Work package 5: Ranking and evaluation of the measures

The aim of this work package is to evaluate various traffic safety policies and to provide a ranking of publicly acceptable measures in order to meet the traffic safety targets of the Flemish government, while ensuring that the available resources are used in the best possible way. By making a thorough evaluation, we will provide a sound underpinning of the Flemish policy in these domains. We consider three broad categories of safety measures: enforcement (public and private), infrastructural measures and educative insight programs. In addition, it introduces the concept of amenability to treatment in order to help policymakers in the decision process.

Project 5.1: Efficiency of road safety enforcement

In this project the focus is on enforcement. In Belgium, the traffic fine revenues are allocated to the police zones according to a given scheme. Each of the police zones can use the fine revenue for well-defined tasks. For some priority actions extra funds are available. This project aims to answer the following questions related to the efficient use of these funds:

  • What is the most efficient allocation of the fine revenues over different zones and tasks?
  • Is there any role for adding private enforcement in an efficient traffic safety policy?

Project 5.2: Amenability to treatment

In this project the focus is on the prospect of implementing measures that will reduce a road safety problem. We propose a general framework for the choice among policy measures. First of all, by measuring the size of the problem and the public support to do something about it, the concept can be used to decide whether to tackle a certain traffic safety problem or not. Secondly, when the answer is positive, amenability to treatment can help to decide which measures are the most appropriate, considering three important elements:

  • Effectiveness: to what extent does a measure lead to the predefined goals?
  • Public support: do people support this measure and are they willing to accept it?
  • Costs: how much does the measure cost?

We will integrate the available expertise about these three elements and create an accessible evaluation framework that allows assessing easily the strengths and weaknesses of particular measures.

Project 5.3: Impact of infrastructural road safety measures on traffic safety

A lot is being done to improve the Flemish road infrastructure and consequently to improve traffic safety. However, the impacts on safety of these investments often are not known very well. Ex-post evaluation of the infrastructural interventions is important so that one can adapt the measures where necessary and one can learn from it for the future. In addition, ex-ante and ex-post evaluation help to ensure that the available resources are used well given the policy targets that are put forward. In this project we therefore evaluate changes in the road infrastructure and its management in terms of their effectiveness and the costs and benefits for the Flemish society. Where relevant, we pay attention to network effects of local measures, which may arise when such measures cause traffic to reroute.

Project 5.4: Measuring is knowing: evaluating the effectiveness of an educative insight program

Educative insight programs have flourished recently under impulse of the apparition of the Goals for Driving Education (GDE) matrix. The programs focus on higher-order skills and address the motivational orientations behind driving. Despite their rising popularity, also in Flanders, there is no clear view on their effectiveness. It is therefore recommended to carry out an evaluation of these programs. We propose to subject the Flemish educational insight program Verkeersgetuigen (an educational program in which traffic victims are involved in traffic safety education) to an outcome effect evaluation on the basis of which policy recommendations can be proposed as to how the program studied could be (further) improved.
