SPR-4306: Back of Queue Warning and Critical Information Delivery to Motorists

Based on the existing INDOT real-time queue-monitoring systems, this proposal focuses on developing a back-of-queue warning and critical information delivery to motorists approaching congestion queues on Indiana highways. The proposed research aims to investigate feasible solutions for deploying end-of-queue alarms through different smartphone Apps, tune parameters and optimize HMI for better user experience; develop a prototype back-of-queue alerting system based on probe vehicle data, and evaluate the benefits via driving simulator study and limited on-road driving test.
