Konferensbidrag (refereegranskat)abstract
- Failure to perform appropriate visual checks at intersections may have contributed to the 2069 cyclist fatalities in the European Union in 2015. This study investigates whether and when car drivers perform visual checks for potentially encroaching cyclists during right-turn maneuvers at urban intersections. UDrive naturalistic data from instrumented vehicles in France, the Netherlands, Poland, and Great Britain were used. The dataset consisted of 852 right-turn maneuvers (UK: left-turn, throughout this document) across 56 drivers. In the six seconds prior to the maneuver, drivers checked their blind spot in 4% of the cases. This frequency increased to 8% when the maneuver was included. The prevalence of cyclist facilities was highest in the Netherlands, which is also the country where blind spot checks were performed most often. When not checking the blind spot, drivers mostly looked toward the road they were turning into. Country predicted neither the timing of sideway glances, nor whether there was any (right) sideways glance. Our findings may inform driver training to increase awareness of cyclists at urban intersections, as well as the design of other traffic safety measures.

Interactions with vulnerable road users
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Within UDRIVE there has been a specific focus on pedestrians, cyclists and Powered Two Wheelers (PTWs). These groups of road users are particularly vulnerable in traffic because they lack the protective shell that helps preventing serious injury once involved in a collision. In addition, these transport modes have several features that make them more prone to getting involved in a crash, e.g. related to reduced conspicuity and for the two-wheelers the difficulty to remain in balance, either or not in combination with high speeds. This type of factors make that pedestrians, cyclists and PTWs have a high risk of getting fatally or seriously injured in traffic.Within UDRIVE, a large amount of ‘naturalistic’ data was collected to get more in-depth insight in the interactions of these groups with passenger cars and trucks. The aim was to identify and understand the everyday behavioural patterns in these interactions as well as the circumstances of conflicts or safety critical events in these interactions. The current Deliverable reported on the analyses and results of a number of specific interaction types.
