Retrospective Theses and Dissertations
The ever increasing traffic congestion being experienced on urban freeways has caused attention to be focused on methods for improving traffic operations on these facilities. The reduction or elimination of freeway congestion can be handled in two basic ways: 1) by increasing the freeway's capacity defined as the number of vehicles per unit time that can pass a given point in one lane of the freeway multiplied by the number of lanes on the freeway, or 2) by decreasing the traffic loads imposed on these freeways. Monumental costs and adverse public relations are involved in the construction of either new …

Retrospective Theses and Dissertations
This report analyzes freeway data from a moving merge control system in Tampa, Florida. The distribution of velocity at sensors in the roadway is plotted and compared to a normal distribution. The size of the gaps at each sensor are computed and compared to those at a sensor downstream. The distributions of the change in gap size are plotted for all gaps and then for gaps between the same pairs of vehicles, to determine the effects of prohibiting lane changing. The expected time of arrival of the gaps at a point downstream are computed, compared to the actual time of …
