Title
Evaluate the Understandability of Information Display Board Signs Using a Driving Simulator Experiment
Abstract
The main research question of this study was how to apply the design guidelines for traditional Changeable Message Signs (CMSs) to the design of the full-color and full-matrix LED Information Display Boards (IDBs). Three categories of messages were evaluated in this study, including (1) travel-time messages, (2) transit travel-time messages, and (3) Graphic Route Information Panels (GRIPs). A driving simulation program was developed based on real-world videos and used to evaluate the designed signs in terms of understandability and helpfulness for decision-making. A total of twenty-four local commuters participated in the driving simulator experiments. Results show that: (1) the perceived easiness of five-line travel-time message is significantly lower than the baseline three-line message, (2) the perceived helpfulness of the transit logo is significantly higher than the generic symbol, and (3) there is no significant difference between the drivers' comprehension of the three-line message and the single-link GRIPs.
