Transport problems such as congestion and pollution are often described as commons dilemma problems (see Vlek, et al., 1993; Van Lange, et al., 1998). These problems are neither caused nor can they be solved by single individuals. They are typically collective problems. People therefore do not feel personally responsible for the problems and they do not feel in control over the solutions (Dawes, 1997). One way to break such a dilemma could be participation. A commons dilemma can be broken by increasing feelings of efficacy and responsibility. Active participation and communication can be a helpful instrument in achieving this. If all individuals and/or stakeholders actively participate in a decision making process they would all feel more responsible for and in control over the problems and solutions. However, this will only work if participation processes are well-designed and carried out. A well designed participation process can lead to the empowerment of individuals. Empowered people feel that they have control over their community and initiate efforts to improve the community (Zimmerman, 1999). Disempowerment can occur when authorities encourage citizens to invest energy in elaborate processes that have no real chance of influencing the outcome (Reich, 1991).
