| Acceleration/Deceleration Lanes | |
| Description: Improvements to infrastructure designed to accommodate trucks’ technical acceleration and deceleration specifications, especially when merging into traffic at intersections, interchanges, ramps, highways, and at traffic signals | |
| Targeted mode: All traffic | Geographic scope: Corridor |
| Type of initiative: Infrastructure management: minor improvements | Primary objective: Improve inadequate infrastructure |
| Expected costs and level of effort to implement: The planning process should involve multiple stakeholders to account for the impacts and benefits of acceleration and deceleration lanes. Depending on the locations, high investments may be needed to acquire land to construct the lanes. Requires analysis of possible environmental impacts. | |
