Stated choices and simulated experiences: Differences in the value of travel time and reliability

Surveys with stated choice experiments (SCE) are widely used to derive values of time and reliability for transport project appraisal purposes. However, such methods ask respondents to make hypothetical choices, which in turn could create a bias between choices made in the experiment compared to those in an environment where the choices have...

Urban travel time data cleaning and analysis for Automatic Number Plate Recognition

Data recorded by Automated Number Plate Recognition (ANPR) cameras can be used to determine several important traffic characteristics, such as real time travel time, travel time statistics, travel time reliability and OD matrices. In this paper ANPR data collected in Chinese city Changsha have been validated. Travel time extracted from ANPR...

Simulation-based travel time reliable signal control

This paper addresses a travel time reliable signal control problem. Travel time distributional estimates are obtained from a stochastic microscopic traffic simulator. The estimates are embedded within a simulation-based optimization algorithm. Analytical approximations of the simulated metrics are combined with the simulated data in order to...

Urban travel time reliability at different traffic conditions

The decision making of travelers for route choice and departure time choice depends on the expected travel time and its reliability. A common understanding of reliability is that it is related to several statistical properties of the travel time distribution, especially to the standard deviation of the travel time and also to the skewness....

Reliability Assessment of the Accessibility of Multimodal Transport Networks

The impact of route guidance, departure time, and alternative routes on door-to-door travel time reliability: Two data-driven assessment methods

Conventional travel time reliability assessment has evolved from road segments to route level. However, a connection between origin and destination usually consists of multiple routes, thereby providing the option to choose. Having alternatives can compensate for deterioration of a single route, therefore this study assesses the reliability and...

Modelling travel time reliability in public transport route choice behaviour

The implementation of travel time reliability (TTR) in route choice behaviour is still not very common in transport models, especially not in a public transport context. The reasons probably are that it is difficult to measure and that there is no agreement how it best can be represented in utility functions. Typically, it is represented by a...

Modelling travel time reliability in public transport route choice behaviour

Public transport is known as a sustainable transportation mode. In order to increase demand and cost effectiveness much attention is paid to increase the service quality. One of these service quality aspects is the travel time reliability of a public transport service. However, the monetization of travel time reliability is still a topic of...

Travel Time Reliability and Quality Assessment of a Route Set through Route Aggregation

Conventional travel time reliability assessment focuses either on reliability on route level or the determination of the valuation of reliability in route choice. However, a connection between origin and destination usually consists of multiple routes, thereby providing the option to choose. This study assesses the reliability and quality of the...

Forecasting door-to-door travel time variability caused by incidents

Reliability of travel times is an important indicator of the performance of a traffic system. The congestion caused by incidents is an important cause of the unreliability of travel times. Travel time reliability should be incorporated in social cost benefit analyses for infrastructure investments. With an accurate forecast of travel time...

Quantifying the full reliability benefits of road network improvements

Monitoring Travel Time Reliability on Freeways

Travel time and travel time reliability are important attributes of a trip. The current measures of reliability have in common that in general they all relate to the variability of travel times. However, travel time reliability does not only rely on variability but also on the stability of travel times. This paper clarifies the attributes of...
