JustNu (translated “Right Now”) is SL’s (SL common short form for AB Storstockholms
Lokaltrafik, translated Greater Stockholm Public Transportation Authority) main focus
project to provide the Public Transportation operations four transport types (buses, local trains,
metro and commuter trains) in the Greater Stockholm area with real time traffic information
and data. The main purpose is to provide traffic information on SL transport services to be
available to all customers. This means to provide real-time reliable and easily accessible
traffic information and data, before and during the journey to the traveler, so the traveler can
plan and travel the entire journey with SL.

The City of Austin Traffic Control System is one of the newest and most advanced traffic management systems in the country. The design of the system is highly scaleable and uses commercial off-the-shelf (COTS) hardware. The system was designed to meet the needs of the users, which was to provide real-time video and data information for the timely response to the traffic management requirements of the urban surface roadway network in the City of Austin.

This paper presents a discussion of the design criteria and system architecture of the project followed by a description of some of the equipment that makes up the system and concludes with a discussion of the benefits seen as a result of the implementation of the system. As a result of the implementation of this system, the City of Austin has seen a noticeable reduction in the time it takes to respond to traffic signal trouble calls. In addition, the system has provided a means to implement or improve traffic signal synchronization on the City’s arterial corridors.

The acronym for MTA Bridges & Tunnels’ Advanced Traffic Management Incident Detect/Evaluate/Act System, ATM IDEAS, is true for the deployment project as well. Awarded as a design-furnish-install-test-maintain contract to Transdyn Controls, Inc., with Dunn Engineering Associates, PC, providing administrative and quality assurance services, the $12M project is using Internet-enhanced weekly teleconferences, status reporting and project management tools, and file sharing. In emulation of open-source code development, modular software development is contractually viewable by the sponsoring agency from the beginning, and paired with written documentation standards, continuous configuration management and complete off-site modular testing prior to deployment. Other project innovations include statistical task analyses based on two 24-hour observations of real TMC operations, a rapid-prototyping mock-up for user feedback and human factors analysis, the use of GIS field device configuration data, effective integration of varying audio and video sources, and the use of electronic white boarding techniques. Planned for simultaneous deployment in 2004 in the Authority’s eleven existing TMCs and a new centralized coordinating virtual TMC, the ATM IDEAS project is an early example of second-generation TMC systems engineering and software development techniques.

Tehran- the capital of Iran- is the largest city of the country with more than 8 million people residents, 600 square kilometers wide, it serves more than 4 million vehicles and 4 million motorcycles as well, over a large scattered road network consisting of 4 active metro ways and 5 active bus rapid transit lanes. Nevertheless, deficiency of transportation systems in Tehran has been led to achieve the first place in the world in air and noise pollution. At 1980, Tehran municipality lined a border around the city center, and defined a traffic congested area through which any entry for the vehicles since then needs permission. Although such permission is only granted to a very small group of people like physicians, there was still a great trespassing rate due to the insufficient capability of control. Till the past year, all the entry roads to the restricted zone were controlled by police officers. There are as much as 5 million vehicles passing the borders monthly of which 20 percent or 1.1 million is illegal. Thus, efficient controlling is a major need, and if systemized, it can deliver vital information of traffic data. Since the past year, Tehran traffic Control Company, implemented an automated control of the borders, using 103 high res. Cameras, which contributed to detect more than 80 percent of illegal entries, and has become a very useful tool to collect traffic data for further analysis. This paper discusses this success story.

After briefly stating the principle of GPS technology, the paper synthetically analyzes  the research  background of the surv-control and navigation of GPS vehicle management system. Also its latest research situation in China and abroad is introduced. The paper emphasizes the study on the unique surv-control and navigation of GPS vehicle management system which adapts to the China’s situation.  Then the system’s design procedures are expounded and the
software’s frame and function of every section are set up. The software tool—MapInfo which can combine map with  text information perfectly and its notable characteristics of the table GIS are detailedly introduced. In the end, prospect of GPS and GIS applications in the surv-control and navigation of vehicle is looked into future. Based on analyzing and comparing the characteristic of three system program development software, MapBasic, VB, VC++ and comprehensive consideration VC++ is selected as the system development software.
