Improving traffic safety for pedestrians and cyclists at signalized intersections: A study of the traffic signal system in Gothenburg

Abstract

It is more important than ever to work towards a sustainable society. The transportation sector has a big potential to contribute to a greener environment. Transport modes such as walking and cycling have been promoted as sustainable options for transportation and have become a challenge for many cities to increase their use. One of the cities is Gothenburg. Gothenburg has adopted many policies and programs to achieve a more accessible city for pedestrians and cyclists. This master’s thesis studies how the current traffic system relating to traffic signals works in Gothenburg and identifies traffic safety problems for vulnerable road users at signalized intersections. The result obtained from this master’s thesis shows a need for a more effective technological solution for the traffic signal system. There are some inconsistencies between the goals stated in supporting documents and implementations. The guidelines need to be clearer and more consistent to avoid conflicting interpretations. Much information is not up to date, such as information on the LHOVRA strategy. Therefore, the current documents and implementations need to be reviewed and updated regularly based on feedback and results. Additionally, this study suggests speed limit measures, clearer road markings, and leaning rails for cyclists to improve traffic safety for pedestrians and cyclists. Further research on different detection methods is recommended for continuing the work on improving traffic safety in Gothenburg.
