Travel demand matrix estimation for strategic road traffic assignment models with strict capacity constraints and residual queues

This paper presents an efficient solution method for the matrix estimation problem using a static capacity constrained traffic assignment (SCCTA) model with residual queues. The solution method allows for inclusion of route queuing delays and congestion patterns besides the traditional link flows and prior demand matrix whilst the...

Potential Impact of Operational Towing on Aircraft Emissions

In this paper, the emissions mitigation potential of implementing operational towing at major European airports is evaluated. Using mixed-integer linear programming, a scenario simulating mixed taxiing operations is used to find the relationship between fixed vehicle costs and target emission savings at an airport and European level. Using...

Optimal locations for rescheduling infrastructure in public transport networks: Enhancing the robustness value against disruptions for Amsterdam tram network

Public transport networks are vulnerable to disruptions which have negative impacts on passengers, operator and society. New rescheduling link in PT networks has potential to increase its robustness value against disruptions. The research project deals with identifying the optimal locations of such rescheduling infrastructure in PT network which...
