This study investigates how highway nuisances are traded off against accessibility gains and other residential characteristics in the moving intentions of people living near highways. It studies a potential mediating role for residential satisfaction and potential mitigating relationships with highway nuisance perceptions. Structural Equation Modelling was used to test a proposed framework based on survey data collected from 1220 respondents living within 1000. m from a highway in the Netherlands.The results show that higher levels of perceived highway nuisances are associated with increased intentions to move, mediated by lower residential satisfaction. However, better perceived accessibility was not associated with either lower moving intentions or lower highway nuisance perception. Highway usage/interest and other residential characteristics - such as satisfaction with buildings, traffic safety, and amount of greenery - seem to countervail perceived highway nuisances as they reduce moving intentions and reduce highway nuisance perception. Finally, the results show that some groups - for example home owners - were less inclined to move (direct effect), independently of their residential satisfaction.From a practical perspective, a more inclusive perspective on highway planning, which accounts for accessibility and other residential characteristics as potential compensators and mitigators for highway nuisances, would be effective to reduce residential stress which could prevent protest and consequent cost overruns of projects. © 2014 Elsevier Ltd.

This article summarizes the results of a study of the Netherlands Institute for Transport Policy Analysis (KiM) on costs and benefits of cooperation between port authorities (Wortelboer en Kolkman, Samenwerking tussen Zeehavens, December 2008). The article elaborates on the question whether, and if so, how, cooperation between port authorities can contribute to our societal welfare and what role the national government can play in promoting this cooperation. © 2010 Taylor & Francis.

The limited coordination between public and private actors in the fields of traffic information and management has led to reduced efficiency and sometimes undesirable situations. The main objective of the Strategic Council for Traffic Information and Traffic Management installed by the Dutch Ministry of Transportation is to develop a joint strategy for the development and the organization of traffic information and traffic management by public authorities and private parties. This strategy will outline future developments and related actions, as well as the organization and roles of the relevant actors for traffic management and information activities. To satisfy these requirements, a proposed scenario-based approach entails sketching different scenarios to describe the situations in 2015, 2020, and 2028 for public and private stakeholders involved in traffic management and traffic information. The approach to determine these scenarios, the scenarios themselves, and their implications are described. The developed scenarios were built around the dimension of freedom of choice of the traveler. After extreme scenarios were identified, possible scenarios were sketched and were linked to instruments and to multiple objectives. On the basis of the scenarios, no-regret activities (those beneficial regardless of scenario) were identified as part of the robust strategy forming essential elements for all possible scenarios. These no-regret activities reflect an important outcome of the project; they entail setting up the value chain of traffic information, setting up a data warehouse to share all relevant data (including the functional and technical standards), and preparing for integrated network management and cooperative systems.

This study aimed to demonstrate that travel time reliability und road network robustness from the user's perspective could be measured with the use of detailed traffic data and according to a definition proposed by international experts. These measurements can be used to describe and explain the trend of travel time reliability and to describe the trend of extreme travel time delays (or nonrecurrent congestion). In the Netherlands, The trend of travel time unreliability increased until 2008 but was followed by a decline in subsequent years until 2011. Socioeconomic factors, such us population growth and employment, appeared to be the underlying factors for the increase in travel time unreliability. Serving as a counterbalance were various transport policy measures, such as the addition of lanes, traffic management, and speed limitation and control, which were implemented primarily during the years 2009 to 2012. Finally, the study demonstrated how the volume of travel time reliability could be used as a component for the cost-benefit analyses of adding infrastructure and for calculating the social costs of travel time unreliability for users of the main trunk road network.

The sale of electrically assisted bicycles ('e-bikes') is growing at a rapid rate across Europe. Whereas market data is available describing sales trends, there is limited understanding of the experience of early adopters of e-bike technology. This paper investigates the motives for e-bike purchase, rider experience and perceived impact on mobility, health and wellbeing through in-depth interviews with e-bike owners in the Netherlands and the UK.Findings revealed that the motive for purchasing e-bikes was often to allow maintenance of cycling against a backdrop of changing individual or household circumstances. E-bikes also provided new opportunities for people who would not otherwise consider conventional cycling. Perceptions of travel behaviour change revealed that e-biking was replacing conventional cycling but was also replacing journeys that would have been made by car. There was also a perception that e-biking has increased, or at least allowed participants to maintain, some form of physical activity and had benefitted personal wellbeing. Technological, social and environmental barriers to e-biking were identified. These included weight of bicycle, battery life, purchase price, social stigma and limitations of cycle infrastructure provision.Additional research is necessary to quantify actual levels of mode substitution and new journey generation among new e-bike owners and the impact of e-biking on promoting physical health and mental wellbeing. © 2016.
