Increasing traffic leads to increasing severity, spatial extension and duration of congestion. Congestion has two immediate consequences. One is that travel times increase on average. Another is that travel times become increasingly variable and unpredictable. When performing economic appraisal of transport policies it is important to account for both.

TRAVEL TIME VARIABILITY OF FREEWAY WEAVING SECTIONS
IFAC Proceedings Volumes, 2006Abstract Traffic operations on weaving sections are characterized by intense lane changing manoeuvres and complex vehicle interactions, which can lead to certain variations in travel time. One of the factors affecting the travel time variability of weaving sections is the length of the weaving section.

The variable radius covering problem with fuzzy travel times
International Conference on Fuzzy Systems, 2010Location Set Covering Problem (LSCP) is a traditional problem in the location literature. LSCP is used in locating fire stations, computer networks, and many other service facilities. This paper proposes a covering problem with variable radii. In this problem, the cost to establish a facility is a monotonically increasing function of distance to the ...

An Empirical Study of Travel Time Variability and Travel Choice Behavior
Transportation Science, 1982Although reliability of travel modes has generally been found to be one of the most important attributes of transportation systems, few attempts have been made to make these findings operational. The impact of a specific measure of reliability, the variability of travel time, on the route-to-work choice is investigated in this research through the use

Traveling waves with dispersive variability and time delay
Physical Review E, 2003We first determine an approximate traveling wave profile for the Cook model [J. Murray, Mathematical Biology I: An Introduction (Springer, New York, 2002), pp. 471-478] for the case in which the number of dispersers is small relative to the number of nondispersers. The results are consistent with the previous linearized wavefront analysis that predicts,

Characterizing Travel Time Variability in Vehicular Traffic Networks
Transportation Research Record: Journal of the Transportation Research Board, 2012Modeling travel time reliability requires characterizing travel time distributions. Two key statistics commonly used to describe a distribution are the mean deviation and the standard deviation, with one depicting the central tendency and the other describing the dispersion.

Statistical Model for Forecasting Link Travel Time Variability
Journal of Transportation Engineering, 2009In the field of advanced traveler information systems, travel time reliability contributes significantly to the utility of traffic information affecting the traveler's choice. The exact estimation of the variance in travel times is fundamental to calculating reliability indices.

Study Travel Time Variability from Probe Vehicle Data
Applications of Advanced Technologies in Transportation (2002), 2002The variability of travel times on a given route for a particular journey is known to be an important factor in influencing the choice of mode and route for trips, particularly for those trip types where constraints may exist on arrival time at the destination.

Public transport travel time and its variability
2017Executive Summary Public transport agencies around the world are constantly trying to improve the performance of their service, and to provide passengers with a more reliable service. Two major measures to evaluate the performance of a transit system include travel time and travel time variability.
