The natural aging of existing roadway infrastructure globally leads to a rise in road work zones for maintenance and rehabilitation. Effective transportation management plans for road projects are essential to minimize traffic delays, ensure safety for motorists and workers, adhere to project schedules, and maintain access for businesses and residents. This presentation emphasizes safety and mobility through examples of pavement rehabilitation, median barrier replacement, and ABC projects.

Strategic maintenance of traffic (MOT) plans and construction sequencing for High Volume-High Speed roadway projects address safe access to and from the work zone with minimal impact on road users. When freeway lanes are occupied due to construction, user delay costs can escalate to millions and lead to community outrage over congestion and safety issues. Non-peak lane closures using plastic delineation is the least expensive way to reduce user delay cost and separate the work zone from travel lanes. However, flexible positive protection options exist. Moveable barrier technology mitigates traffic congestion by quickly establishing lane reconfiguration, under traffic, with the benefit of positive protection to increase work zone safety.

Learning Objectives:

  1. Understand the importance of safety-first approach to traffic management plans where mobility is also critical
  2. Learn from real-world infrastructure rehabilitation and ABC project summaries around mobility and safety
  3. Learn about technology-based solutions for safety and mobility in interstate and ABC work zones
