- Conventional bike-sharing schemes have been introduced in cities as an urban mobility option, reducing car usage and alleviating public transport; however, cycling shares in Göteborg is one of the lowest in Europe. Göteborg has been dedicated to increase the share of sustainable transport in the city. The Electric bicycle (E-bike), which offers a greater form of service than the conventional bicycle, then appears to be rather interesting to policy makers. This study is carried out with the goal to open the door for E-bikes in Göteborg by identifying potential for change from car users to E-bike users. First, the current situation of Swedish perception on cycling and policy were analysed with a literature review. Second, we explore whether E-bikes can remove barriers or provide the same benefit of the alternative modes for people in Göteborg. At the third phase, the geographical potential of E-bikes in Göteborg was identified on three bases: the ratio of cyclist using cars for commuting purposes, travel distance, and the barriers removed. The result suggested that E-bikes theoretically remove the barriers expressed by 53% of people in Göteborg when comparing to regular bicycles. A public E-bike pool is a good solution for overcoming the first two phases of behavioural change, by demonstrating the technology and creating a public supply of E-bikes. Hisingen is the area with the greatest potential to adopt E-biking habits, setting up an E-bike pool in Hisingen can hypothetically substitute around 5% of commuting trips done by the car users who have the capacity to cycle. For the entire Göteborg area, up to 4% of the trips less than 10 km could be replaced by E-bikes. Together with the proper policy strategy, a change towards sustainable transport mode could be realized supported by wide acceptance among the general public.

- In-vehicle technologies and cooperative services are attracting a lot of attention for their potential to deal with congestion problems and improve traffic safety. This paper aims to investigate the impact of infrastructure-to-vehicle cooperative systems, case of COOPERS, at the aggregate level, on traffic performance. A factorial experiment is designed with two factors: traffic demand and penetration of the system with three levels each. In total, nine scenarios are investigated. To replicate driving behavior with and without the system, speed distributions from a simulator experiment are used. A motorway section of 4 km is built in VISSIM simulation software. Indicators such as speed, density, delays and travel times are chosen to evaluate and compare the motorway performance with and without the system. The results show that drivers driving with the system activated are more aware and alert to near future traffic conditions compared to driving without the system. Driving with the system activated is characterized by smoother and longer speed decelerations when approaching critical incident/accident events. The results show as well that the factors investigated significantly impact the motorway performance. Congestion reduces the impact of the system whereas higher penetration levels improve traffic operation on the motorway. Future research directions can include (1) investigating the impact of the system at the micro level such as lane changing or car-following behaviors; (2) levels of compliance with the system, which is an important aspect as well.
