This paper discusses how to decide a path for a vehicle to move to the destination. A space where vehicles move around is composed of space objects. The objects are structured in a hierarchical tree named a space tree. Objects at a higher level denote broader area than ones at a lower level in the space tree. In this paper, we present a method for each vehicle to decide a path whose part nearer...

A structural model is provided for traffic assignment to a transit model. It deals with a hierarchy of layers from passenger to network passing by vehicle, service route and line, while taking advantage of the spatial structure of service routes and lines. A range of capacity effects are addressed: in-vehicle passenger capacity, access-egress capacity in relation to dwelling time, platform occu...

In this paper, we study a novel vehicle sequencing algorithm for an isolated intersection with a new control method. The control method is based on the utilization of Vehicular Infrastructure Integration and the consideration that each vehicle arrives individually. We consider knowledge of each vehicle’s arrival time and the time each vehicle needs to traverse the intersection. Our objective is...

The problem of vehicle–bridge dynamic interaction system under articulated high speed trains is studied in this paper. A dynamic interaction model of the bridge-articulated train system is established, which is composed of an articulated vehicle element model and a finite element bridge model. The vehicle model is established according to the structure and suspending properties of the articulat...

A new, systematic approach to the design-evaluation-test product development cycle is described wherein the vehicle design and simulation environments are integrated. This methodology is applied to brake mechanical design and material selection. Time-domain computations within a vehicle dynamic simulation environment account for brake and lining geometry and material properties, actuator proper...

Absolute positioning of vehicles is based on Global Navigation Satellite Systems (GNSS) combined with on-board sensors and high-resolution maps. In Cooperative Intelligent Transportation Systems (C-ITS), the positioning performance can be augmented by means of vehicular networks that enable vehicles to share location-related information. This paper presents an Implicit Cooperative Positioning (...

We report progress on the various separate problems necessary for the Urban Challenge. We can distinguish vehicles from non-vehicles at long range, track their position and orientation over time, and estimate their velocity and future heading; results are presented from real traffic data. In simulation, we can conduct entire Urban Challenge missions, including construction of the elaborate traj...

In order to understand the overtaking behavior of, overtaking physical separation events between bicycles and mopeds was taken out. According to the analytical model of road bicycle passing events vehicle spatial features, the bicycle passing events into free events overtaking, adjacent events and blocked events, and based on the bicycle traffic flow velocity distribution characteristics and bi...

A Highway Intelligent Space System (HISS) is proposed to study vehicle environment perception in this paper. The nature of HISS is that a space sensors system using laser, ultrasonic or radar sensors are installed in a highway environment and communication technology is used to realize the information exchange between the HISS server and vehicles, which provides vehicles with the surrounding ro...
