Right Turn Avoidance Routing – Planning Optimized Routes That Avoid Right Turns Using the Route4Me Web Platform

Many companies such as UPS and thousands of other businesses that have to solve complex routing problems use a unique approach for planning their routes which is to avoid left turns as much as possible (right turns in the countries where they drive on the left side of the road). Even though with this approach routes can turn out to have longer distance and total travel time on paper, the routes that avoid right turns in the countries with left-hand traffic can actually be more fuel-efficient, less accident-prone, more suitable for special equipment, and so on. Regardless of the intersection type, the vehicles that are turning right in the left-hand traffic have to idle longer since they either must wait for the traffic light to give the right signal or have to wait for the oncoming traffic lane to clear up. Thus, avoiding right turns makes even more sense in big cities with heavy left-hand traffic where idling can add up and result in substantial fuel expenses and CO2 emissions. Moreover, studies show that left turns are more dangerous than right turns (right turns in the countries with left-hand traffic) since making a left turn involves more risks and requires to make such dangerous maneuvers as driving through the oncoming traffic with an obstructed view, etc. In certain cases, some insurance companies can consider the vehicle that turned right in the left-hand traffic to be more liable for the accident. Depending on your particular business needs or unique business model, with Route4Me, you can effortlessly optimize the most efficient and cost-effective routes that will avoid as many right turns as possible and help you to prevent more accidents, improve your visitation times, and significantly decrease your fuel expenses.

Once the route’s settings are updated to avoid right turns, the route’s directions are changed to avoid turning right as much as possible while preserving the same sequence of stops. NOTE: Changing the route’s directions does not change the route’s sequence of stops.

After changing the route’s directions to avoid right turns, you can also re-optimize it to get the most efficient sequence of stops with the shortest route time and distance. To do so, in the Route Editor, go to “Route” and then select “Re-optimize this route” from the menu.

Once the route with updated directions is re-optimized, the route’s total time and distance will get more optimized/shorter and the route’s sequence of stops will change accordingly.
