1. Towards computational models for road-user interaction: Drivers overtaking pedestrians and cyclists
Sammanfattning : Introduction: Crashes resulting from a failed interaction between drivers and vulnerable road users, such as pedestrians or cyclists, can lead to severe injuries or fatalities, especially after failed overtaking maneuvers on rural roads where designated refuge areas are often absent, and impact speeds high. This thesis contains two studies that shed light on driver interaction with either 1) a pedestrian or 2) a cyclist, and oncoming traffic while overtaking. LÄS MER
2. Effects of Safety Measures for Pedestrians and Cyclists at Crossing Facilities on Arterial Roads
Sammanfattning : The principal aims of this thesis are to define suitable measures for safer pedestrian and cycle crossings on arterial roads, to implement these measures on a large scale and to acquire an insight into their effects on road users' safety, experiences, mobility and the environment, by creating a 30 km/h milieu at the above crossings. Two characteristically different types of measures, physical measures and variable message signs, based on three principles, lower speed, no priority and improved and relevant information, are tested within the framework of this project.

3. Seriously injured road users in rural and urban road traffic in a Swedish region - a Vision Zero perspective
Sammanfattning : Globally more than 50 million people are injured in road traffic every year. The incidence of road injuries is increasing while that of fatalities is decreasing. Road safety measures are being implemented in many countries to reduce the effects on public health. In highly motorized countries, the process is often managed by quantitative targets. LÄS MER
4. Environmental Impacts of Shared Mobility: Potential, Factors, and Assessments
Sammanfattning : Environmental impacts from passenger transportation continue to increase globally due to a rise in kilometers traveled and a shift to emission-intensive transportation modes (from public transportation and active modes such as walking and cycling to motorcycle and car ridership). The electrification of the passenger fleet, coupled with low-carbon energy sources, is expected to decrease some of the environmental impacts associated with passenger transportation, including local air pollution, greenhouse gas emissions and fuel depletion.

5. Driver interaction with vulnerable road users: Modelling driver behaviour in crossing scenarios
Sammanfattning : Every year, more than 5000 pedestrians and 2000 cyclists die on European roads. These vulnerable road users (VRUs) are especially at risk when interacting with cars. Intelligent safety systems (ISSs), designed to mitigate or avoid crashes between cars and VRUs, first entered the market a few years ago, and still need to be improved to be effective. LÄS MER
