Assessing Detroit Regional Traffic Conditions

Using Intelligent Transportation System Data Civil Engineering

• Intelligent Transportation System (ITS) data can measure and monitor the

operational performance of the Detroit road network as conditions change,

including new public transportation, construction zones, and winter operations

• ITS data can provide speed mobility graphs which can be used as a method

for analyzing cost-benefit calculations

• The speed mobility graphs quantify travel time delays along I-75 by analyzing

566 traffic message channels (TMC) that produced 983,778,775 travel time

data points over a 5 year period[1]
