Traffic signal controllers timestamp the first pedestrian actuation that requests service, but they do not count the people arriving before the Walk indication. We test a theory-based estimator that ...
Most of you received the TransportLab: July 2026 post, so I gave you a pause. Also traveling to Beijing, Chengdu, and Hangzhou China last month. You might have noticed the site logo changed. Been ...
Gao, Y. and Levinson, D. (2026) A stochastic queueing model for travel time reliability with spatial density heterogeneity. Transportation Research Part B, Volume 211, September 2026, 103544. [doi] ...
Induced demand is usually interpreted as additional capacity reducing generalized cost and producing more travel. When a network exhibits Braess’s paradox, an added link raises user-equilibrium cost, ...
STREET, short for Simulating Transportation for Realistic Engineering Education and Training, is a set of web-based simulation modules built to improve teaching in undergraduate units that cover ...
This paper presents a network origin–destination estimation (NODE) method for trip distribution that applies a percolation-like graph search to allocate trips from origins to destinations. Expanding ...
The interaction between regional access to opportunities and local density of residences has been central to questions of urban structure. However, real-world dynamics often diverge from idealized ...
The allocation of road space among different transport modes has long been a key issue in urban planning, yet it lacks solid theoretical foundations. This paper investigates the optimal allocation of ...
Welcome to the latest issue of The Transportist, especially to our new readers. Happy New Year to all who celebrate. There is a new global Association Of Sustainable Transportation Researchers. Seems ...
Abstract: We introduce Access Surplus as a welfare measure that frames accessibility in a market-like form: the inverse cumulative cost to reach the next opportunity is the ‘supply,’ and the ...
The figure below shows plans (slightly better than the Crayon doodlings we all do) published by the Sydney Morning Herald (apparently obtained from YouTube channel TrainGuy4 — watch the video for ...
The relationship between place and the plexus (the web of networks that connect places) parallels that between messages (information and entertainment content) and media (the communications networks ...
