Understanding platoon dispersion is critical for the coordination of traffic signal control in an urban traffic network. Assuming that platoon speed follows a truncated normal distribution, ranging from minimum speed to maximum speed, this paper develops a piecewise density function that describes platoon dispersion characteristics as the platoon moves from an upstream to a downstream intersect...

VANET (Vehicular Ad Hoc Network) is a special case about MANET (Mobile Ad Hoc Network), has also received extensive attention as a part of ITS(Intelligent Transportation System). Mobility model is the basic research in VANET, our objective is set up a vehicular mobility model reflecting the real-world scene. In this paper, we propose a mobility model at intersection and present mathematical ana...

[1] Research at the intersection of hydrology and ecology is central to a future in which human and ecological needs for water are met. We briefly identify several compelling research questions at this intersection, then focus on a critical research area central to hydroecology: river and stream restoration. Challenges in this area include the development of science to evaluate the effectivenes...

Vehicular Ad Hoc Networks is a promising technology that can widely apply to monitor the physical world in urban areas. Efficient data delivery is important in these networks and optimal route selection is vital to improve this factor. Vehicular mobility is a reflection of human social activity and human trajectories show a high degree of temporal and spatial regularity. Therefore, vehicular dr...

In this paper we focus on the problem of identifying interesting parts of the video. To this end we employ the notion of Bayesian surprise, as defined in [1, 2], in which an event is considered surprising if its occurrence leads to a large change in the probability of the world model. We propose to compute this abstract measure of surprise by first modeling a corpus of video events using the La...

A mixed traffic flow feature is presented on urban arterials in China due to a large amount of buses. Based on field data, a macroscopic mixed platoon flow dispersion model (MPFDM) was proposed to simulate the platoon dispersion process along the road section between two adjacent intersections from the flow view. More close to field observation, truncated Gaussian mixture distribution was adopt...

Uncontrolled intersections are the intersections where there are no external signs or signals to control the movement of vehicles. In mixed traffic conditions priority rules are often violated by the road users. In All-way-stop-controlled intersections (AWSC), the vehicle should stop themselves before they enter the intersection and should check whether any vehicles are present in the other app...

This paper deals with modelling of traffic networks for control purposes. A modular framework based on coloured timed Petri nets is proposed to model the dynamics of signalized traffic network systems: places represent link cells and crossing sections, tokens are vehicles and token colours represent the routing of the corresponding vehicle. In addition, ordinary timed Petri nets model the signa...

Giving priority to buses at traffic intersections is a common practice in busy urban areas. Benefit for buses results from reduction of their journey times and improving their service reliability. However the negative impacts of such priorities for other intersection user’s e.g. individual traffic may exceed the buses benefits. In the paper two-level dynamic intelligent traffic control feedback...
