Travel times in quasi-dynamic traffic assignment

By extending static traffic assignment with explicit capacity constraints, quasi-dynamic traffic assignment yields more realistic results while avoiding many disadvantages of dynamic assignment. We analyse the computation of travel times in quasi-dynamic assignment models. We formulate requirements for the correctness of resulting travel times,...

Optimizing Tailored Bus Bridging Paths

Metro disruptions due to unexpected events reduce transit system reliability, resulting in significant productivity loss and long passenger delays. Bus bridging strategy is often used to connect stations affected by metro disruptions such that passengers could continue their journey. The literature usually designed bridging routes and then...

Extending the Link Transmission Model with general concave fundamental diagrams and capacity drops

Kinematic wave theory consists of two main equations: the conservation of vehicles and the equilibrium flow-density relationship. Assuming that each traffic state along a road at each point in time is an equilibrium state, these combine into a single partial differential equation for the propagation of traffic along a network link. Newell (1993)...

Propagating Agents with Macroscopic Dynamic Network Loading: Challenges and Possible Solutions

While agent-based modelling of traffic demand is gaining attention, a macroscopic dynamic network loading model may be beneficial, particularly in large-scale applications. We investigate the implications of coupling such models, with inclusion of en-route choices, for the modelling of links and the determination of turning fractions, yielding...

Containing urban sprawl: An integrated improvement of space-tranport strategies to reduce air pollution emission

Diverse effective strategies have been designed to minimize the phenomenon of urban sprawl. Previous research focused on the link between spatial and transport development strategies to achieve this goal, with the intention of increasing mobility, reducing commuting time and travel costs. However, a side effect of urban sprawl is an increase of...
