The rapid progress of information technology (IT) may provide us new insights into understanding traffic phenomena, and could help mitigate traffic problems. One of the key applications of IT to traffic and transport analysis is the identification of the location of moving objects using the global positioning system (GPS). It is expected that detailed(More)
In this study we proposed two Quasi-Newton methods to deal with traffic assignment in the capacitated network. The methods combine Newton formula, column generation and penalty techniques. The first method employ the gradient of the objective function to obtain an improving feasible direction scaled by the second-order derivatives. The second one is to(More)
This paper proposes the methodology to evaluate the road network anti-hazardous ability by the concept of network capacity reliability. The methodology proposed here considers the area-traffic regulation, which may be implemented when a large disaster occurs in Japan. The model to calculate entry permission rates is formulated as MPEC (Mathematical(More)
