One of the key issues of stochastic traffic assignment (STA) is to make the flow pattern consistent with the practical results. In this paper, the author makes a summary of STOCH algorithm and puts forward a new algorithm to solve the problem of stochastic traffic assignment called k-shortest-paths-based method. First, the paper discussed the widely used STOCH algorithm, especially for “single-...

In this study, a traffic management measure is presented by combining the route guidance of Advanced Traveler Information System (ATIS) and the continuous network design (CNDP) to alleviate increasing traffic congestion. The route guidance recommends the travelers to choose the shortest path based on marginal travel cost and user constraints. The problem is formulated into a bi-level programmin...

Due to advances in the field of internet things (IoT), transmission speed become very important and need be discussed. Doing proper assignment appropriate channels generated traffic SDN based IoT can affect enormously. Software Defined Networking has been evolved as a supporting technology improve performance networks increase quality. Different machine learning algorithm used for prediction ne...

intentional assignment of entitlements (as opposed to debts) is a legal institution which is based on the possibility of separation of entitlements from the personality of creditor and of its assignment to a third party. in the voluntary assignment of entitlements, the creditors may assign their rights to a third party. after long discussions, voluntary assignment of rights has been accepted in...

In this paper, we present a cyclically time-expanded network model for simultaneous optimization of traffic assignment and traffic signal parameters, in particular offsets, split times, and phase orders. Since travel times are of great importance for developing realistic solutions for traffic assignment and traffic signal coordination in urban road networks, we perform an extensive analysis of ...

nowadays, the environmental impact of transportation project and, especially air pollution impacts, are major concerns in evaluating transportation projects. based on this concern, beside definition of traditional objective functions like total travel time and total investment cost, different type of environmental related function is considered as objective function in urban network design. in ...

Optical time division multiplexing (OTDM) allows multiple traffic streams to share the bandwidth of a wavelength efficiently. In this paper, we present a new analytical model, based on the inclusion-exclusion principle from combinatorics, for evaluating the blocking performance of time-space switched optical networks with fixed routing and random wavelength/timeslot assignment. This model can b...

In this paper, we consider the traffic grooming routing, and wavelength assignment (GRWA) problem for optical mesh networks. In most previous studies on optical mesh networks, traffic demands are usually assumed to be wavelength demands, in which case no traffic grooming is needed. In practice, optical networks are typically required to carry a large number of lower rate (sub-wavelength) traffi...

We consider the problem to estimate time-dependent origin– destination matrices from traffic counts. We propose an iterative algorithm, based on difference quotients, for expressing how the link flows are changed with respect to a change of the travel demand. The method is an extension to previously proposed methods for the time-independent case. It has been implemented together with the mesosc...
