TLDR
A model for the transit assignment problem with a fixed set of transit lines is described, formulated as a linear programming problem of a size that increases linearly with the network size that solves the latter problem in polynomial time.Abstract:
We describe a model for the transit assignment problem with a fixed set of transit lines The traveler chooses the strategy that allows him or her to reach his or her destination at minimum expected cost First we consider the case in which no congestion effects occur For the special case in which the waiting time at a stop depends only on the combined frequency, the problem is formulated as a linear programming problem of a size that increases linearly with the network size A label-setting algorithm is developed that solves the latter problem in polynomial time Nonlinear cost extensions of the model are considered as wellread more

A review of urban transportation network design problems
TL;DR: This review intends to provide a bigger picture of transportation network design problems, allow comparisons of formulation approaches and solution methods of different problems in various classes of UTNDP, and encourage cross-fertilization between the RNDP and PTNDP research.

Transit Assignment for Congested Public Transport Systems: An Equilibrium Model
Joaquin De Cea,Enrique Fernandez +1 more
TL;DR: A new formulation for the assignment problem over congested transit networks is proposed, which considers the congestion effects due to insufficient capacity of system elements transit lines to be concentrated at transit stops.

Network knowledge and route choice
TL;DR: Ben-Akiva et al. as discussed by the authors presented evidence that a majority of travelers fail to minimize travel time or distance, and showed that travelers with more network knowledge appear to vary their commute route to respond to changing travel conditions.

Crowding in public transport systems: Effects on users, operation and implications for the estimation of demand
TL;DR: In this article, the authors examined the multiple dimensions of passenger crowding related to public transport demand, supply and operations, including effects on operating speed, waiting time, travel time reliability, passengers wellbeing, valuation of waiting and in-vehicle time savings, route and bus choice, and optimal levels of frequency, vehicle size and fare.

Network-based Accessibility Measures for Vulnerability Analysis of Degradable Transportation Networks
TL;DR: The results indicate that the accessibility measures derived from the combined travel demand model are capable of measuring the consequences of both demand and supply changes in the network and have the flexibility to reflect the effects of different travel choice dimensions on the network vulnerability.
