The Problem Urban areas face increasingly acute vehicular traffic congestion. Current methods for measuring traffic flow on a real-time basis are antiquated and limited in their capacity to assess traffic dynamics. Buried inductive loop detectors at intersections are extensively used in the USA and Europe to measure traffic speed, occupancy and volume on freeways and arterials. The data obtaine...

As it known, roads constitute the backbone of any cities and also determine urban activity. In addition to this, vital role road network has arise in event a disaster for public response group. The principal services such as first aid, food, personal cleaning, etc. are provided through gathering areas especially 72 hours case emergence. Accordingly, accessibility these great importance. While p...

This project was conducted to investigate new concepts, new tools and emerging technologies directed at enhancing traffic operations and safety on signalized urban arterials that operate under saturated conditions. McFarland Boulevard, a six-lane urban arterial running north-south through Tuscaloosa, AL served as the research focus and test bed for the project. There are nine urban intersection...

The desirable goal in passenger transportation is moving more people in fewer vehicles. This goal, in respect of road transport, can be attained by encouraging public transport modes like buses by assigning priority. This paper is concerned with the conceptual framework of a micro simulation model of highly heterogeneous traffic flow and application of the model to study the impact of exclusive...

In this paper is going to be proposed a Cell Transmission Model (CTM), its analysis and evaluation with case study, which addresses in detailed way the aspect of merging diverging operations on urban arterials. All those few CTM models that have been developed so far, model intersections, some limitations drawbacks. First, unlike simple composition road networks, such as highways, arterials mus...

The concept of a collector-distributor lane system, as part of a regional arterial street improvement program is introduced. Such a system can improve operational aspects of certain urban arterial streets by provision of a transitional space between through-traffic streams and entering-exiting streams. Facilities for which this concept is most applicable, are arterial streets along which develo...

Urban traffic networks consisting of partially blocked roads often need to remain open before, during and after disasters because their vital roles hazard preparation, emergency response recovery urban communities. To conduct effective planning disrupted transportation highly depends on accurate prediction travel time roads, which is very different from that intact roads. Due the lack appropria...

Web-based mapping technologies have been increasingly utilized for traveler information systems. However, most such systems focus on freeways rather than arterials or urban streets. This paper presents a Google-map-based online system for urban traveler information broadcast and analysis. Open source web tools and emerging web technologies, such as Ajax, are used to implement the proposed syste...
