Study of Platoon Dispersion Models
نویسندگان
چکیده
In this study, field investigation is made by means of videotapes which record traffic flows at several locations on two links in Changchun City, China. After processing the data, traffic flows at each location and vehicle speed distributions on different links are obtained for the platoon dispersion process. The platoon dispersion patterns from the observations are compared with those provided by the Transport and Road Research Laboratory (TRRL) in the United Kingdom. Different platoon dispersion models were used to fit the observed vehicle speeds and travel times, and their applicability was discussed. Simulations based on these models showed that the delay and length of queue at the downstream intersection are independent of platoon dispersion models and only depend on the flow and average travel time of vehicles from the upstream intersection.

A Platoon Dispersion Model Based on a Truncated Normal Distribution of Speed
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...
متن کاملMixed Platoon Flow Dispersion Model Based on Speed-Truncated Gaussian Mixture Distribution
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...
متن کاملThird-order Decentralized Safe Consensus Protocol for Inter-connected Heterogeneous Vehicular Platoons
In this paper, the stability analysis and control design of heterogeneous traffic flow is considered. It is assumed that the traffic flow consists of infinite number of cooperative non-identical vehicular platoons. Two different networks are investigated in stability analysis of heterogeneous traffic flow: 1) inter-platoon network which deals with the communication topology of lead vehicles and...
متن کاملAn Integrated Approach for Platoon-based Simulation and Its Feasibility Assessment
Research on developing mathematical and simulative models to evaluate performance of signalized arterials is still ongoing. In this paper, an integrated model (IM) based on Rakha vehicle dynamics and LWR model is proposed. The IM which imitates actuated performance measurement in signalized arterials is described using continuous timed Petri net with variable speeds (VCPN). This enables systema...
متن کاملUpdated Traffic Flow Dispersion Model Considering Effects of in-Vehicle Advisory Messages
Traditional dispersion models; such as the travel time distribution based normal distribution model and geometric distribution model; are dedicated to traffic situations with conventional traffic signs and signals; which may not be able to depict the platoon dispersion phenomenon under a connected vehicle system with in-vehicle advisory messages. This research re-examines the traditional disper...
