Abstract

As technology continues to advance, the outdoor advertising industry is taking advantage of electronic signs, some of which are Static Electronic Signs (SES), with the ability to automatically change the message shown on the sign at regular intervals. Research studies indicate that SES has a negative impact on drivers' visual attention and on vehicle control. However, the actual effects of the SES on the number of collisions have been difficult to prove conclusively. The objective of this paper is to generate a clear understanding of the safety impacts of SES on the number collisions by conducting a before-and-after analysis with comparison groups. The analysis was based on a total of 10 SES along the Highway 27 and the Gardiner Expressway of the City of Toronto. The results of the before-and-after study revealed there was not enough evidence to suggest that these signs have any impact on road safety along the adjacent roadway sections at a 95% confidence interval. The same results were obtained by comparing collisions occurred during daylight and artificial light.
