A Transportation Network Paradox: Consideration of Travel Time and Health Damage due to Pollution

Zhaolin Cheng, Laijun Zhao, Huiyong Li
2020 Sustainability  
In addition, high health damage significantly affects route choices and traffic flow distribution.  ...  Consequently, the classical Braess paradox is no longer realistic because it only considers the traveler's value of time (VOT).  ...  Third, high health damage significantly affects route choices and traffic flow distribution, but the health damage we define in the paper depends on the traffic flows along links, the travel time, and  ...

Multi-agent based vehicular congestion management

Prajakta Desai, Seng W. Loke, Aniruddha Desai, Jack Singh
2011 2011 IEEE Intelligent Vehicles Symposium (IV)

Transport capacity constraints on the mass transit system: a systemic analysis

Fabien Leurent
2011 European Transport Research Review  
These operations are subject to various capacity constraints, depending on the traffic type and the situation in the system.  ...  A public passenger transit system is complex, because it involves two types of traffic unit, passengers and vehicles.  ...  In running a system, they need to be avoided and prevented, or at the very least detected and their consequences managed.  ...

A Pareto-improving hybrid policy for transportation networks

Ziqi Song, Yafeng Yin, Siriphong Lawphongpanich, Hai Yang
2013 Journal of Advanced Transportation  
Chair: Yafeng Yin Major: Civil Engineering Since its inception over 90 years ago, congestion pricing has been recognized by many as an efficient method for alleviating traffic congestion.  ...  This dissertation focuses on a class of congestion pricing strategies that is Pareto-improving (i.e., a pricing scheme that benefits society while ensuring that no one in the system is worse off).  ...  The optimization problem is equivalent to the formulation in Abrams and Hagstrom (2006) of finding a Generalized Braess Paradox.  ...

An East Asian renaissance: ideas for economic growth

2008 ChoiceReviews  
The Braess paradox states that taking away space in an urban area may actually improve the flow of traffic. Conversely, adding capacity to a road network may reduce overall performance.  ...  The paradox is named after Dietrich Braess, who, in 1968, noted that, in a network the utilization of which is optimized by users, not administrators, the change in equilibrium flows may result in a higher  ...  This new agenda of domestic integration is the main challenge facing East Asia. Among other things, "renaissance" implies innovative application of culture, learning, and skills.  ...

Cooperative vehicles for traffic congestion management: a multiagent approach

Prajakta Desai
2023
This research aims to alleviate the problem of road traffic congestion by enabling efficient distribution of vehicles in a road network.  ...  The allocation is improved via trading of routes which takes place in the form of "deals", enacted by every agent virtually and in an autonomous, iterative and distributed manner, thereby reducing the  ...  The solution to the Braess's Paradox proposed in [66] consists of a Traffic Management Centre (TMC) agent, Traffic Guidance Centre (TGC) agent and the In-vehicle information System (IVIS) agent.  ...

Robustness and resilience analysis of urban road networks

Wenlong Shang, Washington Ochieng, Ke Han, Panagiotis Angeloudis, China Scholarship Council
2018
This thesis investigates the robustness and resilience of urban road networks (URNs) in the presence of either local or global disruptions.  ...  The problem is approached from the two perspectives of complex network theory and traffic network modelling.  ...  The bounded rationality also induces non-uniqueness of equilibrium solutions, which increases the chance of network paradoxes such as the Braess paradox.  ...
