Interest in driver assistive truck platooning (DATP) through the application of coordinated adaptive cruise control in the freight trucking industry is on the rise due to its expected benefits on the roadway. To investigate traffic flow impacts, as part of a study sponsored by the Federal Highway Administration, a traffic microsimulation model is developed in CORSIM software. This simulation takes place on a segment of freeway in a rural to small urban area on which current traffic volumes range from 1420 to 1620 vehicles per hour per lane. The parameters of headway, market penetration, and traffic volume are varied. The simulation results are analyzed using travel time benefit and average speed as the measures of effectiveness. A general trend of increasing travel time benefit was found as market penetration increases and as headway is reduced. The statistical significance of the simulation results is analyzed using both a t-test and multilevel ANOVA. An adequate choice for the implementation of DATP technology on the roadway with current traffic volume is found to be a headway of 1.00 seconds with a market penetration greater than 20%.
