There are several types of intersections such as merge-roads, diverge-roads, plus-shape intersections and two types of T-shape junctions in urban roads. When an autonomous vehicle encounters new intersections, it is crucial to recognize the types of intersections for safe navigation. In this paper, a novel intersection type recognition method is proposed for an autonomous vehicle using a multi-...

The traffic congestion problem in urban areas is worsening since traditional traffic signal control systems cannot provide] efficient traffic regulation. Therefore, dynamic traffic signal control in Intelligent Transportation System (ITS) recently has received increasing attention. This study devised a multi-agent architecture, the Adaptive and Cooperative Traffic light Agent Model (ACTAM), for...

Due to the inherent discrete nature of sensing, interpolation is a key activity in sensing. Interpolation in urban computing faces an unprecedented inference issue that was not present in large scale traditional sensing environments. Obstacles such as buildings and walls are prevalent in urban sensing, and it is important to consider them in urban sensing interpolation. This paper introduces an...

ITE JOURNAL / JANUARY 2003 INTRODUCTION Approaches to combat urban traffic congestion span from demand management to physical expansion of road capacity. Attempts to shift a part of peak travel from car to high-quality public transit and to times when roads are relatively less crowded sometimes have been successful.1,2 Also, intelligent transportation systems (ITS) have the promise to optimize ...

While two-dimensional maps exist for most urban areas, the descriptions may be incomplete or out of date, or of insufficient resolution for the given application and features such a roads are not described as 3-D objects. Most of the past work on road detection has concentrated on either low resolution, primarily rural roads (usually producing “spaghetti” roads with no notion of intersections),...

The traffic in urban areas is mainly regularized by traffic lights, which may contribute to the unnecessary long waiting times for vehicles if not efficiently configured. This inefficient configuration is unfortunately still the case in a lot of urban areas, where most of the traffic lights are based on a 'fixed cycle' protocol. To improve the traffic light configuration, this paper proposed mo...

This paper proposes an unsupervised vehicle’s tracking and recognition methods for urban Traffic surveillance in a distributed cooperative manner. Vehicle’s matching in a multi-camera surveillance system is a fundamental issue for increasing the accuracy of recognition. In intelligent transportation systems (ITS), especially in field of urban traffic management, intersections monitoring is one ...

1 A reservation-based autonomous intersection control system, named Autonomous Control of 2 Urban TrAffic (ACUTA) is presented in this paper. ACUTA manages autonomous vehicles in 3 the vicinity of an intersection to allow them to pass the intersection without any conflict and few 4 stops. To address the operational issues identified in previous studies on reservation-based 5 autonomous intersec...
