Travel Time Variability Analysis in Stockholm Vehicular Traffic Network

EasyChair Preprint 1851

Abstract

Mean deviation and standard deviation are two key statistics commonly used when analysis travel time variability. However, conventional methods based on the mean or variance of travel time may result in a biased estimate of reliability when the distribution is skewed. In this paper, we aim to validate the relationship between mean, standard deviation, and skewness on multiscale (network and route) and multilevel (day-to-day and within-day), which can be an interesting contribution to the travel time estimation reliability.

Keyphrases: Skewness, linear regression, standard deviation, travel time, travel time variability
