| Abstract | This research is an attempt to determine the shape of the flow density curve, generally assumed to be parabolic or logarithmic. Math ematical models of traffic flow developed by Greenshields and Greenberg are employed in the statistical analysis of experimental data. Of especial interest is the negative-sla pe portion of this curve, from the point of critical density (maximum flow) to the point of jam density (zero flow). A 16-mm cine camera was used to observe the differential spacings, velocities, decelerations, clearances, and headways of pairs of vehicles in a traffic stream as their flow characteristics changed from maximum flow to a stop when the traffic stream was forced to stop due to an external constraint. Chapter I deals with several previous practical and theoretical approaches in car-following theory to define the relationships between speed, density, and flow which are related to this work. The experimen¬ tal phase is treated in detail in Chapter II and the statistical analysis of traffic data extracted from the photographs is discussed in Chapter III. Chapter IV covers discussion of the results and conclusions drawn from the interpretation of the results. The last part of this report is devoted to recommendations for further study. |
