Estimate Freeway Exit Sign Locations
Considering that a driver decides to exit a highway upon seeing the guide sign upstream of an exit, subsequently the driver in an inside lane or the middle lanes must move onto the outside lane prior to exiting. The concern is whether the driver can accomplish this task safely and smoothly. It is apparent that an upstream exit sign cannot be placed too close to an exit or too far beyond several exits upstream. The MUTCD recommends that the sign should be placed 1 mile and 2 miles upstream of an exit without explaining the reasons for selecting the 1 mile distance. By integrating driver decisions, vehicle acceleration characteristics, tire-road traction into a single analytic framework, the location upstream of an exit where an exit sign should be installed is determined for a driver to get off at the right exit successfully. Practitioners can easily apply these user friendly formulae and equations derived from the framework to compute the required distance ‘D’ between a highway exit and an upstream exit sign for guiding drivers to exit the highway safely. Additionally, parameters for these formulae can be adjusted to resemble various exiting scenarios.
