Event

The seminar week 41 is hosted by Professor Robert Thomson, Chalmers. The topic for this seminar is SAFER’s international collaborations, more specifically CTS. The China-Sweden Research Centre for Traffic Safety is a network of Chinese and Swedish organizations coordinating joint activities that address vehicle and traffic safety. An overview of the partnership and the current activities will be presented. SAFER supports the center and is the focal point for Swedish activities. _____________________________________________________________________________________

SAFER Pedestrians

Speaker: Robert Thomson, Professor, Vice Head of Department – responsible for research and doctoral studies - Department of Mechanics and Maritime Sciences, Chalmers 

The Vinnova and MOST co-funded projects related to vulnerable road user safety are “SAFER Pedestrians” – sponsored by Vinnova and “Development of vehicle preventive and active safety technologies and the applications in integrated pedestrian protection” sponsored in China by MOST. The Swedish project is led by Chalmers and involves VTI, Volvo Car Corporation, and Autoliv. The Chinese team is led by Tsinghua University and involves University of Technology and Science Beijing, RIOH, Geely, and Brilliance Auto.

The two teams are working on complementary activities with the main items being:

1)    Pedestrian detection and tracking – UTSB
2)    Pedestrian reactions and Injury prediction – Tsinghua
3)    Pedestrian head injuries and model development - Chalmers  

The presentation will provide an overview of the activities in the two different projects with an outlook to the coming research topics.

CTS – Heterogeneous project overview (Heterogeneous Traffic Groups Cooperative Driving Behaviours Research under Mixed Traffic Condition)

Speakers: Maytheewat Aramrattana, researcher at Department Traffic and Road-users, VTI
Eleonora Andreotti, post-doctoral researcher in Vehicle Safety Division of Mechanics and Maritime Sciences Department, Chalmers

In early deployment stage of automated driving technology, it can be foreseen that there will be a mixture of autonomous and manually-driven vehicles, which is referred to as mixed traffic or “heterogeneous” traffic in this project. Impacts of autonomous vehicles on traffic flow and safety under this circumstance are investigated in this project. This presentation will give an overview of the project and some preliminary results.

The speakers will also present the following publication:

Safety-centred analysis of transition stages to traffic with fully autonomous vehicles

The aim of this paper is to highlight and investigate the effects of increasing presence rate of autonomous vehicles (AVs) in terms of traffic safety and traffic flow characteristics. For this purpose, using existing driver models in traffic simulator SUMO we identify and analyze those parameters that characterize and distinguish AVs' driving from manual driving in a heterogeneous traffic context. While it is essential to identify the parameters for traffic flow characteristics of heterogeneous fleets compared to homogeneous ones comprising manually driven vehicles (MV) only (i.e. current status), the safety aspects must be also accounted for. In order to combine these two fundamental aspects of heterogeneous traffic, we used a complete description of a highway driving scenario. The scenario integrates the perceptions of different type of vehicles (i.e. AV and MV) involved and the reaction times of human drivers and decision-making units of autonomous vehicles, to explore the impact of both the rate of AV presence and the perturbation in perception capabilities in highway scenarios.
