Virginia Smart Road

The Virginia Smart Road , Also Known As simply the Smart Road gold Smart Highway , [2] is a short, limited access road in Montgomery County, Virginia , used for the testing of pavement and technologies as a proving ground for new transportation technologies. The Smart Road is currently a 2.2-mile (3.5 km) stretch of road with turn-around loops at either end. Eventually, the road will be extended to a total of 5.7 miles (9.2 km), qui will Directly connect US Route 460 in Blacksburg to Interstate 81 with an interchange near mile marker 121; However, there is no set time frame for completion. The Wilson Creek Bridge was built for the Smart Road and at 175 feet (53 m) tall, is the second tallest bridge in Virginia . [3] The road and bridge are operated and maintained by the Virginia Department of Transportation . [1] It is also part of the Proposed Interstate 73 Corridor.

Vehicle infrastructure integration

Vehicle Infrastructure Integration ( VII ) is an initiative Fostering research and applications development for a series of technologies Directly linking road vehicles to Their physical surroundings, first and foremost in order to Improve road safety . The technology draws on several disciplines, including transport engineering , electrical engineering , automotive engineering , and computer science . VII. (1). (2). Planes , for example, use ground-based beacons for automated guidance, Allowing the autopilot to fly the plane without human interference. In highway engineering , improving the safety of a roadway can improve overall efficiency. VII targets improvements in both safety and efficiency.

Urban Traffic Management and Control

The Urban Traffic Management Control or UTMC program is the main initiative in the UK for the development of a more open approach to Intelligent Transport Systems or ITS in urban areas . Originating as a government research program, the initiative is now managed by a community forum, the UTMC Development Group, which represents both local transport authorities and the systems industry.

Traffic signal preemption

Traffic signal preemption (also called traffic signal prioritization ) is a type of system which permits the normal operation of traffic lights to be preempted. The most common use of these systems is to manipulate traffic signals in the path of an emergency vehicle , halting conflicting traffic and allowing the emergency vehicle right-of-way, to help reduce response times and enhance traffic safety. [1] signal preemption aussi can be used by light railand bus rapid transit systems to allow public transportation priority access through intersections, or by railroad systems at crossings to prevent prevention collisions.

Traffic estimation and prediction system

Traffic estimation and prediction systems ( TrEPS ) have the potential to improve traffic conditions and reduce travel delays by facilitating better utilization of available capacity. These systems exploit currently available and emerging computer, communication, and control technologies to monitor, manage, and control the transportation system. They also provide various levels of traffic information and trip advisory to system users, including many ITS service providers, so that travelers can make timely and informed travel decisions.

Need for TrEPS

The success of ITS technology deployments is heavily dependent on the availability of timely and accurate estimates of prevailing and emerging traffic conditions. As such, there is a strong need for a traffic prediction system. The needed system is to please use advanced traffic models to analyze data, Especially real-time traffic data, from different sources to estimate and predict traffic conditions na That proactive Advanced Traffic Management Systems(ATMS) and Advanced Traveler Information Systems (ATIS) strategies can be ………………….

Research

USA

In the United States, the FHWA R & D initiated a Dynamic Traffic Assignment (DTA) research project in 1994 to meet the need for a traffic prediction system. The objective of this research is hand to Develop a deployable real-time Traffic Estimation and Prediction System (Treps) to meet the information need in the ITS context. In October 1995 two parallel research contracts Were Awarded to Massachusetts Institute of Technology (MIT) and the University of Texas at Austin (UTX) with a follow-up development and media at the University of Maryland (UMD) respectivement. Each team was required to develop a prototype of TrEPS demonstrating its potential for real-time application capability. After three years of intensive R & D efforts, two prototype TrEPS were developed. The two prototype TrEPS developed by MIT and UTX / UMD are named DynaMIT -R and DYNASMART -X, respectively. Both systems are simulation-based DTA system.

France

In France, the National Center for Traffic Information (CNIR), coordinators and monitors of the regional traffic and coordination centers (CRICRs). It publishes its website at www.bison-fute.equipement.gouv.fr/en/ and is widely referred to in radio and television broadcasts. The advice of “Bison Futé” as the service is called is well known and has been in place for several decades.

China

In China, Xi’an Jiaotong University (XJTU) initiated a similar simulation-based DTA research project in 2000 with a follow-up development and support at the Shandong Academy of Sciences after 2004. Dr. Yong Lin is the project leader and Houbing Song Is the earliest project member. After six years of intense R & D efforts, one prototype TrEPS was developed in 2006. The overall prototype TrEPS developed by Dr. Lin and his team has more than 20 members is named DynaCHINA (Dynamic Consistent Hybrid Information Based on Network Assignment).

Singapore

Singapore Implemented the first practical implementation of congestion pricing in the world in 1975, the Singapore’s Area Licensing Scheme . [1] [2] Thanks to technological advances in electronic toll collection , detection, and video surveillance, Singapore upgraded ict system in 1998. [3] (see Singapore’s Electronic Road Pricing )

In an attempt to Improve the pricing mechanism and to Introduce real-time variable pricing , [4] Singapore’s Land Transport Authority , together with IBM , ran a pilot from December 2006 to April 2007, with a traffic estimation and prediction tool, qui uses historical Traffic data and real-time feeds with flow conditions from several sources, in order to predict the levels of congestion up to an hour in advance. By accurate estimating prevailing and emerging traffic requirements, this technology is expected to allow variable pricing , together with Improved overall traffic management, Including the provision of information in advanced to alert drivers about the conditions ahead, being white and the prices charged at That Moment. [5] The pilot results show overall prediction results above 85 percent of accuracy. Furthermore, when more data was available, at peak hours, [6]
