Safety Performance Assessment of Stop-Operated Intersection Equipped with Active Road Sign

Aware of the importance of traffic signs, alignments visibility and placement on road safety, deployment of Light-Emitting Diode (LED) signs (also known as Active Road Signs) has been increased especially at locations with known history of potential for high Collision occurrence. The effects of these types of signs are not yet fully understood. The expected benefits of the proposed active signage are enhancing traffic flow efficiency and improving safety of road users, especially under adverse weather conditions and hectic driving environments. To quantify the effects of the proposed treatment, Cross-Section Observational studies in safety and driving behavior has been conducted for STOP sign on a selected test bed. The main objective was to determine the impacts of deploying such treatments on roadway safety and traffic operation. An unbiased comparison has been conducted under same condition with same sample series. The result of this study proves a statistically significant improvement in drivers’ compliance to the required command addressed by the STOP sign. This compliance is either due to attracting driver attention and making drivers more alerted about the driving environment or improvement in perception and understanding the command.
