OPERATING SPEEDS AND VOLUME TO CAPACITY RATIOS: THE OBSERVED RELATIONSHIP AND THE FOLD CATASTROPHE

The paper examines the operating speed and v/c ratio relationship (for a given highway capacity) as an example of a fold catastrophe. The behavioral base of the relationship was established as an optimizing model. The objective function was determined as the overall welfare level of a driver having two components: a utility index and a disutility one. The choice of the speed of travel at a given congestion level was determined by maximizing the overall welfare level of the driver. /TRRL/
