Holistic assessment of traffic management measures and ITS

14 January 2014

With the aim of achieving greater awareness of the impacts of traffic management measures, a set of key performance indicators has been developed to promote a common approach to impact assessment in both the planning and post-deployment phases. These are being used in Brussels and Stuttgart among other cities.

The set of KPIs emerged from the EU-funded CONDUITS project (2009-2011) based on input from some 30 cities from Europe and beyond. A total of 13 KPIs were defined across the main policy areas of traffic efficiency, pollution reduction, road safety, social inclusion and land use. Selected KPIs were then tested in Paris, Rome, Munich, Tel Aviv and Ingoldstadt.

Building on these KPIs, a decision support tool (DST) has been developed with support from Kapsch TrafficCom. CONDUIT-DST (Decision Support Tool) is designed to help decision makers understand what will be the likely wider impact(s) of a particular measure. The tool has been developed in several stages: a first version covering pollution reduction was developed in 2012 and expanded in 2013 to encompass two traffic efficiency KPIs: reliability and mobility.

The CONDUITS KPIs can now be used for ex-ante and ex-post assessment of a traffic management measure.

CONDUITS_DST uses data from the traffic model and emissions profiles. It has already been tested in Brussels on part of a bus route which is being equipped with bus priority at traffic lights. Brussels is now considering mainstreaming its use in all new traffic management measures. Besides Brussels, other cities, including Stuttgart, Tel Aviv and Haifa, have either adopted or are testing CONDUITS-DST and/or the KPIs.

Next steps involve extending CONDUITS-DST to road safety and possibly to social conclusion. In this regard, further case studies are planned.

The CONDUITS tools (KPIs and DST) are free of charge. A manual and technical support are also made available to interested users.
