- W631281486 abstract "From stop-start driving through to stationary queues, traffic congestion in its various forms is becoming an increasingly common feature on the motorway network. Flow breakdown on motorways is a complex phenomenon that occurs under a combination of specific traffic conditions and perturbations in the flow. Certain locations along the motorway aggravate the volatility or provide opportunity for the disturbance to take place. The context of this research is the value of being able to pre-empt the propagation of the sequential braking pattern (known as a shock wave) upstream through dense traffic, thereby providing an opportunity to influence the traffic using speed control. An integrated conceptual framework, consisting of mechanistic, deterministic and probabilistic models has been developed. The mechanistic component explores potential within the stability parameters of car-following models, the deterministic component explores potential for location specific stochastic disturbances, but the main emphasis of the research is on the probabilistic inference. The probabilistic model for the origin of motorway shockwaves requires a detailed description of the present conditions during which flow breakdown occurs, in order to make an inference about the probability relationship involved. Detection of seed points is therefore a critical part of the research needed to complete the probabilistic model. Software has been developed to identify seed points, and descriptions of the proposed algorithms used in the software are presented and assessed on their ability to identify the origin of shockwaves. This paper has shown that it is possible to identify the location of seed-points by classification using traffic characteristics. (A) For the covering abstract see ITRD E121926." @default.
