Title:

Effects of Different Guide Signs on Driver Behavior at Express Lane Entrance: A Driving Simulation Study

Abstract:

Express lanes are freeway lanes that are separated from general-purpose lanes to provide a higher level of mobility. As guide signs in advance of express lanes are used to convey information to drivers who have to react instantly, the manner the information is displayed is of utmost importance. This paper examines the drivers’ understanding of different guide signs at express lane entrance in a driving simulator setting. The tested signs had varying amount and type of information. A total of 15 participants of different ages and genders took part in the study. The results showed that different amounts of information had a significant impact on both the drivers’ comprehension and their driving speeds. The percentage of driver comprehension of signs with high amount of information was found to be 48.8%, and a sign with seven words reduced the speeds of drivers two times more than a sign with six words. Furthermore, the effect of displaying the toll amount on the express lanes and comparative travel times on the general-purpose and express lanes on a single sign versus displaying the information separately on two separate signs was tested. There was no significant difference in drivers’ comprehension while reading a sign with toll amount and a sign with comparative travel time information. However, the drivers’ comprehension of a sign that displays two different types of information (e.g., travel time and toll amount) was found to be significantly lower compared to the sign with just one type of information.
