Abstract
Over 7,600 pedestrians and cyclists died on European roads in 2013. The pressing question is how traffic safety for bicyclists can be increased? Communication is essential in traffic in order to inform other road users and to coordinate their behaviour. The current paper focuses on developing a methodology to analyse cyclists' communication resp. interaction with car drivers and other traffic participants in order to obtain a better understanding of critical events. The relation of communication and infrastructure will be discussed. The general hypothesis is that infrastructure has a marked influence on the communication between cyclists and other road users. It emphasizes the necessity and chances for communication: e. g. a good intersection design enhances the visibility of cyclists.
Highlights
The main aim of the paper is to discuss the theoretical framework regarding definition of safety-critical events and the relevance of communication between different traffic participants of the BIKEALYZE project
Cycling is an increasingly popular alternative transport mode, but there were far too many cycling fatalities over the past decade (European Transport Safety Council 2015). 138,400 pedestrians & cyclists were killed in EU between 2001–2013
That they face a high risk, there is a slower decrease in the rate of deaths of unprotected road users than for motor vehicle users
Summary
The main aim of the paper is to discuss the theoretical framework regarding definition of safety-critical events and the relevance of communication between different traffic participants of the BIKEALYZE project. The Austrian project BIKEALYZE (founded by the Austrian Ministry of Transportation) which started 2015, includes a naturalistic cycling study in the cities of Vienna and Salzburg. Data will be collected by (1) mobile eye tracking, (2) GPS-based motion data acquisition complemented with acceleration and steering direction data, (3) video-based data and 4) elicitation interviews. The paper will focus only on the observation and mobile eye tracking data
