Effects of information feedback on an asymmetrical two-route scenario

Abstract

In traffic system, a reasonable information feedback can improve road capacity. In this paper, we investigate an asymmetrical two-route scenario in which dynamic information can be generated and displayed on the board to guide drivers. Two improved feedbacks (i.e. improved mean velocity feedback and improved congestion coefficient feedback) are introduced. Simulations show that the average cost is dependent on the vehicle arrival rate and there exists a critical the dynamic vehicles ratio corresponding to the maximum flux. We find that improved con-gestion coefficient can better enhance the system capacity than that of improved mean velocity feedback.traffic flow, asymmetrical two-route scenario, information feedback

Power law and small world properties in a comparison of traffic city networks

“…Zhu et al [31] investigated the scaling of directed dynamical small-world networks with random responses. Some other noteworthy results can be seen in [32][33][34][35][36][37][38][39][40].…”

Recent developments in totally asymmetric simple exclusion processes with local inhomogeneity

“…More recently, the use of correlation functions to examine the spatially correlated variability, in particular for inhomogeneity cases, has been considered by Foulaadvand et al [33]. Also recently, Sun et al [34] investigated the effect of information feedback on traffic current in the presence of a single inhomogeneity. Such a model considers the next-step traffic and is resolved via computer simulations, the complexity of the model precluding analytical solutions.…”

A complementary formulation for traffic equilibrium problem with a new nonadditive route cost

“…Gabriel and Bernstein [9] presented a general route cost function with the following form: (4) is reduced to route cost function (2). Also, when disutility function U rs is the identity function, route cost function (4) is reduced to function (1).…”

“…With the rapid development of transportation in recent years the studies of traffic flow and the traffic behaviors have got more and more attention [1][2][3]. Traffic assignment models are widely used as planning tools (for example, four-step sequential planning process) at both strategic and operational levels, in both developed and developing countries, and important decisions concerning investments of infrastructure and transport services are normally supported by evaluation methodologies based on assignment models.…”
