Evaluation from a Corridor perspective: methods and results
The NEXT-ITS 2 project contains a number of measures deployed on the NEXT-ITS 2 corridor and in traffic management centres in order to move from local traffic management towards coordinated and cross-border management of the whole corridor. The evaluation performed has covered the services deployed or enhanced by the road authorities involved during the period 2015-2017, also including some measures completed fully in early 2018. The objective has primarily been to evaluate the costs and impacts of the services deployed i.e. how the measures contribute to reduction in travel time, accidents and emissions from road transport.
The total estimated effects of the services are considerable, about 490 000 vehicle hours driven less and circa 135 000 vehicle hours less spent in congestion annually. About three severe accidents and 11 thousand tonnes of CO2 emissions are avoided annually due to NEXT-ITS 2. The total value of the annual benefits in 2017 will be circa 15 Million €, which can be compared to the implementation costs of circa 33 million € including VAT and thereby comparable to the benefits (the costs without VAT amount to almost 27 Million €). As the annual operation and maintenance costs will be in the order of 3 Million €, the NEXT-ITS 2 can be assessed to be socio-economically profitable.
