Alsau?--lntelligent visual surveillance for road vehicles is a key camponmt for developing autonomous intelligent transportation sys tem. I n this paper, a probabilistic model for prediction of traliic accidents using 3D model based vehicle tracking is proposed. Sample data including motion trajectories are first obtained by 3D model based vehicle tracking. A fuzzy self-organizing neural networ...

in this study, stability control of a three-wheeled vehicle with two wheels on the front axle, a three-wheeled vehicle with two wheels on the rear axle, and a standard four-wheeled vehicle are compared. for vehicle dynamics control systems, the direct yaw moment control is considered as a suitable way of controlling the lateral motion of a vehicle during a severe driving maneuver. in accordance...

Abstract Location-Routing problems involve locating a number of facilities among candidate sites and establishing delivery routes to a set of users in such a way that the total system cost is minimized. A special case of these problems is Hamiltonian p Median Problem (HpMP). In attempting to solve this problem, numerous mathematical formulations have been proposed. Most of them have in common t...

This paper introduces a new intelligent method to generate vector maps from printed maps to provide a basis for GPS navigation. This new approach has been applied in our GIS-DMG (Digital Map Generation) software, which has four key steps: Map Layers Extraction, Road Network Digitalization, Map Geo-locating and Map Automatic Geo-adjusting, different from typical procedures. These four steps play...

In this paper, we describe a method for locating a mobile robot moving in a known environment. This technique combines position estimation from odometry with observations of the environment from a mobile camera. Fixed objects in the world provide landmarks which are listed in a data base. The system calculates the angle to each landmark and then orients the camera. An extended Kalman jilter is ...

Map-matching (MM) is a technique that attempts to locate an estimated vehicle position on road network. Many map-matching algorithms have been developed and widely incorporated into GPS/DR vehicle navigation systems for both commercial and experimental ITS applications. However, the reliability of these systems is still a problem because vehicle position may be located to an incorrect road sect...

This article describes a system for locating a mobile robot moving in a known indoor environment. The simplest method for position estimation of a mobile robot is odometry; but, as the robot moves errors of estimation are accumulated and the accuracy of the estimation decreases. The problem is solved by relocalizing periodically the vehicle by means of external references. Besides the common te...

The Transit Network Timetabling and Scheduling Problem (TNTSP) aims at determining optimal timetables for each line in a transit network by establishing departure and arrival times at each station allocating a vehicle to each timetable. Customers could know departure times of the line runs offered by the system in a regular way. However, each user, traveling later or in advance than their desir...

This specification describes how DNS SRV records, DNS TXT records, and well-known URIs can be used together or separately to locate CalDAV (Calendaring Extensions to Web Distributed Authoring and Versioning (WebDAV)) or CardDAV (vCard Extensions to WebDAV) services. Information about the current status of this document, any errata, and how to provide feedback on it may be obtained at in effect ...
