The method can devise an overall traffic conditions evaluation based on the multiple performance measures. To illustrate our method, an experimental study was undertaken with dual-loop-detector data from 6 freeway sections for the year 2006, and 5 measures were selected for inclusion in this ...

Observations from two freeway bottlenecks in and near Toronto, Canada indicate that the average rate vehicles discharge from a queue can be 10% lower than the flow measured prior to the queue's formation. Absent any influences from downstream, the queue discharge flows exhibited nearly stationary ...
Research (Sun et al., 2017) inputted the information of driving conditions into RBF-NN and improves the model adaptability under different scenarios. Besides, to capture the speed dynamics, the non-linear autoregressive (NAR) neural network also is employed in vehicle-speed thanks to its dynamic...
This article focuses on modelling the acceleration-deceleration behaviour of drivers during freeway weaving manoeuvres, under heavy traffic conditions. The term 'heavy traffic conditions' refers to the period which is fully congested, i.e. queues reside on both freeway and ramp approaches and there...
aMetered ramp traffic is controlled by a traffic signal at some point on the ramp upstream of the freeway merge point. Traffic waiting to enter the freeway queues at the signal. The rate at which traffic is allowed to enter the freeway is determined by freeway traffic conditions measured ...

pointing to a free-flow state. Conversely, as vehicle density rises, the spread of speed narrows, indicating a constrained flow and potential traffic congestion. This transition and narrowing of speed variation may reflect the onset of congested traffic conditions, characterized by reduced and more ...
The design of road tunnels is an essential component in maintaining highway safety and highway design. The need for roadway construction along difficult topography, including overcoming natural conditions, is the major motivation for selecting an alternative solution for a road tunnel. A road tunnel'...
A study for the vehicle lane-changing behavior under rainfall conditions using cellular automata was reported by Zhang et al. (2016), they found in the medium and high densities, the rain causes more traffic congestion, and the frequency and duration of traffic congestion in space–time diagram...
