Integrated Simulation Optimization of Hard Shoulder Running Combined with Speed Harmonization

doi:10.16182/j.issn1004731x.joss.17WJP-019

Abstract

Abstract: We have a study on hard shoulder running (HSR) combined with speed harmonization. The breakdown events were screened out during the study period from massive detector data. The impact of hard shoulder volume on breakdown probabilities was analyzed. The nonparametric breakdown probabilities distribution model and logistic regression model were put forward based on highway mainline traffic volume, hard shoulder volume and ramp volume from the study case which was divided into three factors-basic segment, on-ramp merging segment and off-ramp diverging segment. The speed harmonization and HSR were optimized through reducing the traffic breakdown probabilities of a congested traffic network. The strategies were tested on M42 highway in the United Kingdom, which shows that the method has practical application value.

Key words: active traffic management, hard shoulder running, speed harmonization, METANET traffic flow model
