Delay or travel time information? The impact of advanced traveler information systems on drivers’ behavior before freeway work zones

Peak travel times contribute to congestion formation at freeway work zones. Advanced Traveler Information Systems (ATIS) can inform drivers in real-time about the delays and en-route provide information an alternative route a destination. Different ATIS display strategies are available; however, road authorities lack insights into how time methods sign characteristics influence driving behavior (decelerations, lateral position), drivers’ attention allocation ability subsequent choice before diversion. A simulator study was conducted with 80 State of Qatar investigate drivers' voluntary choices when encountering total (default setting) or delay updates for two routes on Variable Message Signs (VMS) Graphical Route Panels (GRIP). The GRIPs graphical conventional VMS that visual map most direct less congested destination using different color schemes. difference ratio between kept constant compare effectiveness designs towards signs eye-tracker. results showed zero detour did 74–83% take being displayed GRIP free flow attribute framing. When displaying equal times, 25% more follow than VMS. Generally, resulted efficient first location fewer mean decelerations repeated nearing Road advised activate support among drivers.
