Abstract Details

2007, Master of Science (MS), Ohio University, Civil Engineering (Engineering).
The nature of the headways or the interarrival times (IATs) on non-signalized freeway entrance ramps was studied. Cumulative interarrival time distributions for three different entrance ramps with different configurations were developed which can be used in digital computer traffic simulation models. Data collected in the study “Improved Work Zone Design Guidelines and Enhanced Model for Travel Delays in Work Zones” for the Ohio Department of Transportation were used in this study. The IAT distributions for the entrance ramps were compared with the IAT distributions of the lanes for freeways and were found to be close so that the IATs for the selected freeway lanes can be used to approximate the IATs for the entrance ramps. The cumulative IAT distributions obtained for freeways were extrapolated using the hyperbolic relationship to cover low and high traffic volumes outside the empirical observed data range. The IAT distributions were further investigated whether they could be described accurately by a negative exponential, an Erlang with K=2, 3 or a Pearson type III distribution, but no close matches were found.
