В работе описывается двухстадийная модель равновесного распределения транспортных потоков. Модель состоит из двух блоков, где первый блок — расчета матрицы корреспонденций, а второй потоков по путям. Первая модель, используя матрицу затрат (затраты на перемещение одного района в другой, данном случае время), рассчитывает описывающую потребности объемах передвижения другой район. Для решения это...

Network planning and traffic flow optimization requires the acquirement and analysis of large quantities of data such as the network topology, its traffic flow data, vehicle fleet composition, emission measurements etc. Data acquirement is an expensive process that involves household surveys and automatic as well as semi-automatic measurements performed all over the network. For example, in ord...

IYER, VIJAY R. A Simulation Study of Wavelength Assignment and Reservation Policies with Signaling Delays. (Under the direction of Professor George N. Rouskas). This thesis studies the effect of non-negligible signaling delays on the performance of wavelength-assignment heuristics, wavelength reservation schemes, routing schemes, holding time (average being 1/μ) of the lightpaths and traffic lo...

In this paper, we design a dynamic frame length CDMA/TDMA scheme for clustered wireless ad hoc networks with unknown traffic parameters. In this scheme, the collision-free intra-cluster communications are organized by the cluster-heads using a TDMA scheme, and a CDMA scheme is overlaid on the TDMA to organize the interference-free inter-cluster communications. Therefore, to design such a scheme...

This paper addresses a theoretical issue related to combined dynamic traffic assignment and signal control under conditions of congestion through a brief review of previous research and the discussion on interaction between dynamic traffic assignment and signal control. The dynamic characteristics of the interaction are approached using a differential game modeling approach here to formulate th...

In the two preceding papers, we established the so-called J-system as the dynamic system of the traffic assignment problem for static case and developed corresponding numerical solution methods. In this paper, we present J-system formulation of the dynamic traffic assignment problem. Here we first extend the definition of J-functions of First-In-First-Out violation for a dynamic traffic network...

The multi-class reliability-based user equilibrium (RUE) problem has been intensively studied in recent years, as it can capture the route choice behaviors of users with heterogeneous risk-aversion under demand and supply uncertainties. Few solution algorithms, however, are available for solving the RUE problems in large-scale road networks. This is mainly due to the non-additive property of th...
