Abstract

Research to inform policy is often challenged with how to genuinely use and implement research findings in decision-making and policy-planning. To begin with, the dialogue between researchers and decision-makers is essential to ensure profound understanding and legitimate interpretations of the results. Furthermore, the step to drawing practical conclusions and process them into actions can only succeed if research findings are diffused to decision-making levels with influence on the matter and mechanisms to knowledge transfer in the presence of a stable, favourable policy environment exist. Research investments into the topic of electromobility in Europe are substantial, and subtopics aiming to inform national policy-makers address a complex set of aspects from environmental and societal to technological and economic. This paper has a two-fold objective, the first of which is to present the results of scenarios to explore electromobility deployment in Finland, Germany and the European Union. The second is to discuss the challenges and solutions to bridge the gap from research findings towards decision-making and policy-planning, using our electromobility scenario work as an example. The electromobility scenarios were built using the VECTOR21 model (Mock, 2010), and the rationale was to simulate vehicle sales and markets under different policy settings and calculate the most economical solution to fulfil regulation on CO2 emissions as set by the European Commission (2009). The model allows calculating the market diffusion of alternative powertrain technologies to the European market until 2030, taking into account different taxation schemes, incentives and other country-specific characteristics. We also present the cost-benefit-analysis of the modelling results to assess the different scenarios and to show variation between regions regarding profitability of alternative technological or political support and interventions. To proceed from research findings towards decision-making and policy-planning, we made observations relating to transfer of research knowledge and interpretation of our electromobility scenario results in national policy contexts. An evaluation of how the function of research to inform policy in this case succeeded is provided. In addition, the influence of expert opinions on the political decision-making process will be discussed through experiences from an expert questionnaire conducted to survey the importance of costs, time requirement, acceptance and other criteria of promotion measures of electromobility.

Abstract

VK: T20703 The motivation for this study was to investigate the representative volume element (RVE) needed to correlate the nondestructive electromagnetic (EM) measurements with the conventional destructive asphalt pavement quality control measurements. A large pavement rehabilitation contract was used as the test site for the experiment. Pavement cores were drilled from the same locations where the stationary and continuous Ground Penetrating Radar (GPR) measurements were obtained. Laboratory measurements included testing the bulk density of cores using two methods, the surface-saturated dry method and determining bulk density by dimensions. Also, Vector Network Analyzer (VNA) and the through specimen transmission configuration were employed at microwave frequencies to measure the reference dielectric constant of cores using two different footprint areas and therefore volume elements. The RVE for EM measurements turns out to be frequency dependent; therefore in addition to being dependent on asphalt mixture type and method of obtaining bulk density, it is dependent on the resolution of the EM method used. Then, although the average bulk property results agreed with theoretical formulations of higher core air void content giving a lower dielectric constant, for the individual cores there was no correlation for the VNA measurements because the volume element seizes deviated. Similarly, GPR technique was unable to capture the spatial variation of pavement air voids measured from the 150-mm drill cores. More research is needed to determine the usable RVE for asphalt.

Abstract

Over the past decade a large number of Field Operational Tests (FOT) have been conducted to test Intelligent Transport Systems (ITS) in real traffic conditions with thousands of drivers. In order to ensure scientifically sound studies a FOT methodology was developed in the FESTA project. Currently we are on the brink of a new series of large scale FOTs, testing automated and autonomous vehicles. A common FOT methodology serves the following purposes: (1) to ensure that a systematic and scientific approach is taken by FOTs, (2) to enable the assessment of the impact of large-scale introduction of ITS on safety, mobility, efficiency and environment, (3) to be able to compare results of different FOTs, and (4) to build a community and facilitate knowledge exchange. FESTA focuses strongly on the drivers of vehicles, and the changes in their behaviour when driving a vehicle that is instrumented with new systems. In FESTA, it is recommended that driving with an ITS is compared with driving without it (the baseline). However, what will be the focus of the new FOTs? And what will be the main research questions these FOTs will address? And what is the baseline? Three types of focus can be distinguished; centred on the user, the vehicle or the context. In this paper we discuss the requirements for a methodology that addresses these three types of focus. We investigate how the current FOT methodology may be adapted or may need to be completely changed. Special attention is given to the type of data that is needed for baselines and for answering research and impact questions.
