Stop-&-go (S&G) waves are prevalent in congested traffic conditions and are characterised by cyclic patterns of forced deceleration followed by acceleration. These waves lead to an escalated level of frustration among drivers which further influences their physiological characteristics. This study tests the hypothesis that an increase in the number of S&Gs on a route increases its disutility for the driver. A stated choice experiment was designed to study the route choice behaviour of participants who drive regularly by car. A random parameter error component logit model is used to evaluate the willingness to pay (WTP) measures among the presented attributes. Results show a statistically significant WTP measure for the trade-off between travel time and the number of S&Gs. This study expands the literature on the route choice behaviour of drivers to aid the decision-making of transportation planners, in particular on problems relating to network design, management, operation and planning.
