Synchronized flow as a new traffic phase and related problems for traffic flow modelling

Continuum Modelling of Traffic Flow

We wish to consider the problem of modelling flow of vehicles within a traffic network. In the past, stochastic traffic models have been developed [13, 8] in order to investigate a wide range of traffic configurations. However, if the population is sufficiently large, these stochastic processes tend towards a continuum approach. Consequently, this approach is most useful when considering long, ...

Synchronized flow and phase separations in single-lane mixed traffic flow

D PR OO F Abstract In this paper, we have studied synchronized flow and phase separations in mixed (heterogeneous) single-lane highway traffic. It is found that the flux–density (occupancy) curve of heterogeneous flow, as expected, lies in between two flux–density (occupancy) curves of homogeneous flow R 1⁄4 0 (all vehicles are slow vehicles) and R 1⁄4 1 (all vehicles are fast vehicles). Howeve...

Behavioral Analysis of Traffic Flow for an Effective Network Traffic Identification

Fast and accurate network traffic identification is becoming essential for network management, high quality of service control and early detection of network traffic abnormalities. Techniques based on statistical features of packet flows have recently become popular for network classification due to the limitations of traditional port and payload based methods. In this paper, we propose a metho...

Mathematical Modelling of Traffic Flow at Bottlenecks

This master’s thesis gives a brief overview of mathematical modelling of traffic flow from different perspectives. Focus lies on the fluid flow analogy first derived by Lighthill, Whitham and Richards (LWR) in the 1950’s which treats a traffic stream as a compressible one-dimensional fluid. The LWR theory is applied to bottleneck queueing situations, more specifically to junctions with one outg...
