Traffic flow models with ’slow-to-start’ rules
We investigate two models for traffic flow with modified acceleration (’slow-to-start’) rules. Even in the simplest case vmax = 1 these rules break the ’particle-hole‘ symmetry of the model. We determine the fundamental diagram (flow-density relationship) using the so-called car-oriented mean-field approach (COMF) which yields the exact solution of the basic model with vmax = 1. Here we find th...

در این پژوهش مسئله واگذاری ترافیک را از دید سیستم های دینامیکی فرمول بندی می کنیم.فرض کرده ایم که همه فاکتورهای وابسته در طول زمان ثابت باشند و تعادل کاربر را از طریق فرایند منظم روزبه روز پیگیری کنیم.دینامیک ترافیک توسط یک نگاشت بازگشتی نشان داده می شود که تکامل سیستم در طول زمان را نشان می دهد.پایداری تعادل و دامنه جذب را توسط مطالعه ویژگی های توپولوژیکی تکامل سیستم تجزیه و تحلیل می کنیم.پاید...
Metastable States in Two-Lane Traffic Flow Models With Slow-To-Start Rule
Using computer simulations, we show that metastable states still occur in two-lane traffic models with slow to start rules. However, these metastable states no longer exist in systems where aggressive drivers (which do not look back before changing lanes) are present. Indeed, the presence of only one aggressive driver in the circuit, triggers the breakdown of the high flow states. In these syst...
متن کاملAbsence of Metastable States in Two-Lane Traffic Flow Models With Slow-To-Start Rule
It is widely known that one-lane traffic models with slow-to-start rule exhibit phase separation and metastability. In this paper, we show that no metastable states exist in the two-lane version of the VDR model. We show also that the structure of the steady state as well as its corresponding relaxation dynamics depend on the lanechanging probability pch. Moreover, the relaxation time τ diverge...
متن کاملScaling, Modeling and Traffic Control of a Real Railway Network using Max-plus Algebra and Model Predictive Control
Delay time recovery can increase the efficiency of the railway network and increase the attractiveness of railway transport against other transportation systems. This article presents a new dynamical model of railway system. The proposed model is a discrete event systems that is defined based on the deviation of travel time and deviation of stop time of trains. Due to the existence of multiple ...
