Die Dissertation befasst sich mit der Erweiterung und Anwendung des allgemeinen räumlichen Gleichgewicht- und Transportmodells RELU-TRAN (Anas und Liu, 2007) und analysiert verschiedene verkehrs- und klimabezogene Politikmaßnahmen (Tempo-30 in Städten, Infrastrukturqualität, Anpassung an den Klimawandel) in einer Stadtökonomie.

Background: The whole of society is facing major challenges regarding the ongoing climate change and the possibility of creating sustainable development. This also largely applies to today's trafficsystem, which needs to change to more sustainable trffic system. Increased active travel is a nescessery for reaching the set goals that exist when it comes to sustainable travel. Increased active travel will lead to more unprotected road users in the trafficsystem, one group of unprotected road users are pedestrians. An increased number of pedestrians in the trafficsystem requires additional efforts to ensure traffic safety for that group. Method: An scoping review is carried out in which police and legislative measures aimed at increasing road safety for pedestrians are evaluated. The purpose of the study is to gain knowledge about what measures the current research proposes to increase traffic safety and to come up with proposals for additional areas where more research is needed. The study builds on two previous literature studies that superficially touched on the subject. Seven scientific articles are taken from these literature studies, a further 13 scientific articles are selected after a literature search. A total of 20 scientific articles that meet the inclusion criteria are included and analyzed. In order to assess whether Swedish authorities implement effective police and legislative measures with the aim of increasing traffic safety for pedestrians, a comparison is made between the measures proposed by the research and the measures that two Swedish authorities, the Swedish Transport Agency and the Swedish Police Agency, present in their documents Aktionsplan för säker vägtrafik 2022–2025 - 250 åtgärder som 33 myndigheter och aktörer avser att vidta för ökad trafiksäkerhet samt Polismyndighetens strategi inom trafiksäkerhetsarbetet. Results: The study shows that targeted police measures aimed at fining individuals who break traffic rules in a certain place during a certain time have a positive effect on pedestrian traffic safety. The focus should be on increasing rule compliance and reducing the number of speed limit violations by motorists, as well as encouraging pedestrians not to walk against red lights. The legislative measures that the scoping review shows have the best effect are lowering the speed limit and car-free zones on stretches of road where many pedestrians are moving. Conclusions: The conclusions that thos scoping review draws are that further research is required in the connection between reduced average speed and the number of traffic accidents which leads to personal injuries to pedestrians, as well as the part of police and legislative measures in different action programs that include several different measures that are implemented together. The police authority is working towards a reduced average speed of motorists through targeted police measures, which is in line with the measures proposed by the existing research in the area. However, there is nothing in the document about targeted police measures against pedestrians in order to increase rule compliance by that group, which is something that the Police Authority is recommended to develop. In the Swedish Transport Agency's action plan for the years 2022-2025, no measures are mentioned to increase pedestrian traffic safety linked to traffic accidents. Only measures to reduce the number of fall injuries are presented. The Swedish Transport Agency is therefore recommended to further develop its action plan and also have it include legislative measures such as reduced speed limits or car-free zones on road sections where many pedestrians move.
