Travel Time Reliability for Stockholm Roadways

Transportation Research Record: Journal of the Transportation Research Board, 2009
In recent years, there has been an increasing awareness that travel time reliability, apart from expected travel time, is an important component of cost–benefit analysis, especially during congested traffic conditions. A common measure of travel time reliability is standard deviation, and it has been shown that this is a theoretically sound measure ...

Traveling Time Reliability in Sudden Events

International Conference on Transportation Engineering 2009, 2009
Sudden events can make great influence on road network's ordinary operation. Travel time is an important parameter evaluating the performance of road network. The paper analyzes relationship between travel time and traffic flow on a road section, analyzes distribution rule of traffic flow on each routes in a road network and travel time reliability.

The Framework of Assessment on Travel Time Reliability

International Conference on Transportation Engineering 2007, 2007
The potential sources of disruption to transportation network are numerous and little has been accounted for the variability on traffic state, especially travel time. Based on statistics methods, three-hierarchy framework of assessment on travel time reliability is proposed in this paper to show the ability of transportation network dealing with ...

Flow Breakdown and Travel Time Reliability

Transportation Research Record: Journal of the Transportation Research Board, 2009
This paper proposes a methodology for online prediction of travel time reliability based on real-world measurements in light of the probabilistic character of traffic breakdown. A discrete time Markov chain is developed to represent the flow breakdown event.

Travel Time Distribution under Interrupted Flow and Application to Travel Time Reliability

Transportation Research Record: Journal of the Transportation Research Board, 2014
The travel time distribution under interrupted flow based on radio frequency identification–detected data is analyzed. The urban road network studied is in downtown Nanjing, Jiangsu Province, in China, where video cameras and radio frequency equipment are installed at some arterial links to acquire traffic flow data including vehicle type, passing time,

Travel Time Reliability Measures Accommodating Scheduling Preferences of Travelers

Transportation Research Record: Journal of the Transportation Research Board, 2019
Existing travel time reliability measures fail to accommodate scheduling preferences of travelers and cannot distinguish between the variability associated with early and late arrivals. This study introduces two new travel time reliability measures based on concepts from behavioral economics.

Impact of Traveler Information on Road Network Travel Time Reliability

Journal of Transportation Systems Engineering and Information Technology, 2012
To investigate the provision of traffic information on road network travel time reliability, the travelers are divided into two classes: travelers equipped with advanced traveler information systems (ATIS) and travelers unequipped with ATIS. A route choice behavior model considering information guidance is formulated as a mathematical program based on ...

Macroscopic Travel Time Reliability Diagrams for Freeway Networks

Transportation Research Record: Journal of the Transportation Research Board, 2013
Travel time reliability is considered to be one of the key indicators of transport system performance. Knowledge of the mechanisms of travel time unreliability enables the derivation of explanatory models with which travel time reliability can be predicted and utilized in traffic management.
