VRP-based Model for Lane Marking Assessment with MRU Vehicle
Evaluation of lane marking conditions has advanced from visual and/or manual inspections, which can be unsafe and time-consuming, to mobile assessments using vehicle-mounted devices that allow transportation agencies to collect retroreflectivity data at a large scale in a safer and efficient manner. However, cost-effectively routing and operating these mobile retroreflectivity units (MRUs) at a large scale can be a unique challenge. This study proposes a vehicle routing problem (VRP) based model to optimize the routing of MRUs. The model takes into account the additional costs of daily and weekly operations of MRUs, such as remounting the device and traveling between tasks.
