Highway merging points are critical elements due to the interactions between vehicles and following on outermost lane of highway stream. Such could have significant implications for safety capacity at ramp locations. The aim this study was investigate spacing adjustment behavior by interacting drivers In regard, we relied NGSIM trajectory dataset impacts speed difference a space headway, consid...

The flexibility of bus rapid transit (BRT) in scheduling is one of the greatest differences with traditional buses. In order to improve BRT operation quality, the paper studied the headway optimization and scheduling combination of BRT vehicles. A model has been established to minimize passengers’ travel costs and vehicles’ operation cost, and constraints included passenger volume, time, and fr...

( a Department of Civil Engineering, Tsinghua University, Beijing 100084, China) Abstract: Considering high speed following on expressway or highway, an improved car-following model is developed in this paper by introducing variable safety headway distance. Stability analysis of the new model is carried out using the control theory method. Finally, numerical simulations are implemented and the ...

In this paper, a new microscopic traffic model based on forward and rearward driver response is proposed. Driver characterized using the distance time headways. Existing models such as Intelligent (ID) characterize flow constant acceleration exponent. This exponent reflects uniform behaviour during different conditions which unrealistic. slow with large headway quick short headway. Conversely, ...
