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 (...

short-term prediction of traffic flow is central to alleviating congestion and controlling the negative impacts of environmental pollution resulting from vehicle emissions on both inter- and intra-urban highways. the strong need to monitor and control congestion time and costs for metropolis in developing countries has therefore motivated the current study. this paper establishes the applicatio...

This paper presents a novel method MGARS to automatic road area segmentation based on motion and gray feature for the purpose of urban traffic surveillance. The proposed method can locate road region by region growing algorithm with the fusion feature of motion information and grayscale of background image, which is independent to road marker information. An adaptive background subtraction appr...

Intelligent Mobility is the most important pillar in the approach of the smart city because the urban road traffic is the heart of many problems in many fields, such as economics or ecology. Therefore, the Intelligent Transportation Systems (ITS) have emerged to best optimize the expenditure of the user on often complex road networks. In this paper, after studying the backgrounds of such system...

noise pollution can be considered as the most important problem of urban environmental management in mega metropolises and urban transportation is the main source of the mentioned problem. this study aims to investigate the amount of traffic noise dose received by traffic policemen in tehran; district 1 municipality. the investigation was conducted during three consecutive months in 2007 in 282...

As a society, we have seen the quality of our public spaces declining for the past century. Urban areas have become more focused on the transportation of vehicles through the public space, as use of cars has increased, than on the ability of people to enjoy the space. This has led to city streets that function poorly in their ability to move traffic and act as a social center for the area. A ne...

Accurate Annual Average Daily Traffic (AADT) information is important to many applications including roadway design, air quality compliance, travel model validation, etc. Yet complete or even extensive coverage of a network to collect traffic count data is impractical due to the cost involved. There have been studies to estimate AADT for interstate highways, expressways, urban roads, and rural ...

The paper discusses the benefits of specific user’s oriented tools in urban planning processes, throughout the applications of an original system devised to define the localisation of urban services based on traffic distribution. Operative examples concern the Italian city of Pavia. The system ULISSE (Urban Location Interactive System for SErvices), created by the author, uses a static model of...

Urban Traffic Control in developing countries is often a never ending problem due to rapid motorization. Optimization of traffic control is one way to reduce this problem. In this experiment, Genetic Algorithm was adopted to optimize a traffic light and offset between intersections. The objective functions are minimizing delay at an intersection and maximize traffic progressive flows along an a...
