Abstract

Stop-&-go (S&G) traffic is a driving condition characterised by sudden braking followed by acceleration of vehicles. Cyclic occurrences of S&Gs can affect drivers to experience discomfort and create an unsafe driving condition. Past studies have independently conducted stated preference (SP) surveys and driving simulator experiments to understand route choice behaviour under S&G traffic. However, further research is needed in studying if a driving simulator experience prior to the SP survey could yield different results in comparison with an SP comprising description of the scenario. Two SP surveys, with university staff and students, were conducted to assess the route choice behaviour of individuals under S&G conditions. The first survey (SP1) involved introducing participants to S&G phenomenon through written text and animations before presenting the route choice scenarios. The second survey, SP2 was the same as SP1, except that the participants experienced S&G traffic in a driving simulator experiment before attempting the survey. The results from discrete choice analysis show that the mean value of time of drivers in SP2 dataset is 20% lower than SP1. The importance of this study is to understand the reasons for this difference which would potentially help in designing SP surveys which include the realism associated with the expensive driving simulator experiments.
