BEHAVIOURAL ANALYSIS OF DRIVERS' REACTION TO TRAVEL TIME RELIABILITY INFORMATION

Reaction Time of Drivers to Road Stimuli

The assumption of a reaction time value for drivers responding to road situations is fundamental for the design requirements involving sight distance, in particular for vertical and horizontal curves. This response time is frequently referred to as the "perception-reaction time" in traffic engineering literature. Previous attempts to estimate an appropriate value for this time are discussed, al...

Effect of Flashing Brake Lights on Drivers\' Brake Reaction Time ‎and Release Gas Pedal Time

Objective: It is believed that drivers play a crucial role in accidents. Paying attention to brake lights, a driver may find out about danger and react. Rear-end collision accidents refer to the part of the accidents due to driver inattention or slow reaction. The aim of this study was to determine the effect of dynamic flashing brake lights (7 Hz) on drivers' brake reaction time using the driv...

A Freeway Travel Time Reliability Study

The objective of this study was to identify measures appropriate to estimate travel time reliability and apply them to study the reliability of travel time under varying freeway operating conditions. More specifically, a case study was undertaken to study travel time reliability along the I-65 corridor in the State of Alabama. The objectives of this study were to: a) Calculate reliability metri...

A Multi - State Travel Time Reliability Model

Travel time unreliability is an important characterization of transportation systems. The appropriate modeling and reporting of travel time reliability is crucial for individual travelers as well as management agencies. In this paper, a novel multi-state model is proposed for travel time modeling and reporting. The model advances travel time modeling in two aspects. First, the multi-state model...
