Energy use generated by traffic and pavement maintenance: decision support for optimization of low rolling resistance maintenance treatments

Robert Karlsson

VTI has investigated the role of rolling resistance on total traffic energy use and if road maintenance treatments can be a viable option to reduce total traffic energy use. The purpose of the study is to enable road management to better consider the total energy used on roads when managing the road network. The objective is to derive meaningful and simple instruments for decision making situations such as when selecting and designing maintenance treatments, in which total energy use is considered in a multiple criteria analysis. Total energy includes both traffic and maintenance induced energy use. The report focuses on how road management can reduce traffic energy by lowering rolling resistance of pavement surfaces by decreased macro texture and increased evenness. Total energy use is a result of a complex web of parameters in which pavement managers can make a contribution to minimizing total energy, but the complexity implicates that the assessment of consequences of different maintenance options is a challenging task. In order to calculate total energy this report uses the VETO model and a life cycle approach. In this report, two case studies were undertaken in which the energy use for traffic and pavement manager induced actions were investigated in detail. The findings in these two cases were analysed to identify more general relationships that can be used for decision making planning and design of pavement maintenance.



Cost Benefit Analysis (CBA) workshop in Stockholm

An open seminar and workshop in Stockholm will be held on 25-26 April 2018. The workshop deals with the use of CBA as a basis for decision-making in the public sector. The workshop is organized by, among others, Professor Jan-Eric Nilsson, VTI.
