Application of Truncated Distribution to Travel Time on Signalized Road Section

A truncated distribution is used to model the distribution of link travel times in a signalized section of road. Link travel time is decomposed into time in motion (the time a vehicle is actually moving) and time in queue. Time in motion is modeled using a truncated distribution, while time in queue is modeled as a mixed distribution consisting of a mass distribution and a uniform distribution. A probability density function for travel time is then derived and parameterized by fraction of queuing vehicles, red signal time, and motion behavior parameters including truncation points. These parameters are obtained from sample link travel times using a maximum likelihood estimator. The results show that time in motion and link travel time are better modeled by truncated distributions than by non-truncated distributions.
