  Objective: The objective of this research is to investigate the impacts of drivers’ demographic factors on speed patterns in response to a smartphone based warning message, while driving through the advance warning area of a work zone. Methodology: A smartphone application was developed using Massachusetts Institute of Technology (MIT) App Inventor 2, which was used to provide test drivers with a warming message on traffic control and incident awareness. Twenty-four subjects with different demographic features (different gender, age, education background, and driving experience) were recruited to drive through an advance warning area of a work zone twice in two scenarios (with and without the warning message). The advance warning area was divided into three segments for the convenience of analysing the significant difference in subjects&r.. View More»
