Abstract:Over the past decades, fatal crashes and severe injuries have been observed to
increase in highway facilities. This has created a big concern among different
transportation agencies and other organizations such as State Departments of
Transportation (DOT) and the World Health Organization (WHO). One of the most
important components of highway operations that is affected by the increase in crashes
are toll road systems.
Recent toll plaza designs have changed drastically due to the implementation of
new technologies such as Electronic Toll Collection (ETC). Although these emerging
features are developed to improve toll plaza operations, it has altered driver behavior
and increased crash frequency as a result of driver confusion and difficult merging
scenarios that occur when approaching toll plazas with alternative payment methods.
Driving simulators are cost-efficient devices that can be used to understand how these
changes affect driving behavior and safety issues in toll roads without endangering the
health of the participants. Past studies have used driving simulators to evaluate the
effectiveness of pavement markings, crash cushions, traffic control devices, Variable
Message Signs (VMS) and other emerging technologies.
