This was accomplished through focusing on the road user as a main element in highway design in order to create a consistent geometric design. To realize this objective, an experiment was designed to collect driver behaviour data using a test vehicle equipped with various instruments. Thirty volunteers were recruited to drive the test vehicle on a test route. The driver behaviour data collected included vehicle path, steering angle, speed, and lateral and longitudinal accelerations on different road classifications. These data along with the geometric alignment of the highways traversed in the experiment formed a huge database. This database was used to evaluate driver behaviour and analyse the interaction between it and geometric design and safety. This research has provided significant recommendations to the design guidelines for updating the design of horizontal curves and evaluation of design consistency. Examples of the aspects of horizontal curve design covered in this research include determining desirable lengths of spiral curves, driver comfort thresholds on horizontal curves, and recommended values for deceleration and acceleration rates at the entrance and exits of the curve. This paper summarizes the data collection methodology and presents the main contributions of this research.Read More
