نظام آلي جديد لفك الاختناقات المرورية عن طريق الاستشعار عن بعد

تدرس الإدارة العامة للمرور بالسعودية، القيام بتنفيذ مشروع تقني يستخدم أحدث ما توصلت إليه الخبرات العالمية في إدارة الحركة المرورية، وهو نظام التحكم المركزي الآني والآلي للإشارات الضوئية، بحيث يستجيب بصورة فعالة للمتغيرات المستمرة والمفاجئة في كثافة الحركة المرورية على تقاطعات الإشارات الضوئية ويخدم المصلحة العامة، وذلك بهدف معالجة مشكلة الازدحام والاختناقات المرورية في الشوارع والطرقات والتقاطعات الرئيسية التي تتطلب في العادة بذل جهود كبيرة من المسؤولين والمهندسين ورجال الأمن، ويراعي النظام الجديد الذي تعتزم الإدارة العامة للمرور العمل بموجبه قريبا، أوقات المناسبات الطارئة والموسمية التي تشهد حركة مرورية عالية وكثيفة من دون الحاجة إلى إجراء تغييرات في البرمجة، بعكس البرامج الموجودة حاليا والمعدة يدوياً، التي تحتاج إلى إجراء تغييرات مستمرة وموقعية لها.

New automated system to decode traffic jams through remote sensing


Studying the General Directorate of Traffic, Saudi Arabia, to implement technical project uses the latest international experience in the management of traffic, a central control system real-time and automatic signal lights, so as to respond effectively to the variables constant and sudden in the intensity of traffic on the intersections of traffic signals and serve the public interest, in order to address the problem of congestion and traffic jams in the streets, roads and major intersections, which would normally require major efforts of officials and engineers and security officers, and take into account the new system, which intends to General Directorate of Traffic of work which soon, times of events of emergency and seasonal experiencing the movement of high traffic and dense without the need to make changes in programming, unlike the existing programs and stomach manually, you need to make changes to its continuous and on-site.
Al «Middle East» from informed sources, that this system will be applied temporarily and will be the first in the cities of Riyadh and Jeddah, and comes after extensive studies and advanced in response to developments and large changes huge in the cities of Saudi Arabia has grown rapidly in recent times, which has made great strides in the areas of trade and urban and tourism and configure the infrastructure and demographics, and urbanization in the road network big, where will this new system to reduce traffic congestion, by finding solutions that do not require high costs and easy application and implementation do not affect the economic activity and do not need to work large field.

The sources revealed that the system currently applied in a number of developed countries, which is experiencing high traffic density, such as the city of Sydney, Australia, and the city of Dublin, and the city of Cologne, Germany, and the cities of Leicester and Bristol, UK and Singapore.

* The way the system works

* And has shown sources that the way the system works based on the timing perfect for the length of cycle signal and distribution phases (directions) different, in addition to coordination between the signals contiguous manner to reduce the delay and for identifying the signals, and the system relies in its work on the files Ala_i_arip that are placed under the road at every intersection and be connected to control devices, and is moved all the information from the sites to the control center by telephone lines to be analyzed, and then send the results directly to the intersection again, to be implemented effectively and directly and as quickly as possible.

And will be placed sensors on the number of vehicles at an appropriate distance from the line to stand up, so that it is receiving accurate information is the number of vehicles and the length of a row of vehicles parked, and then this information is sent to the control center for analysis and decision-making appropriate to change the times of the signal through telephone lines, and to identify the border accurately , for the capacity of the intersection method and the movement of vehicles in the intersection.

Will also be monitoring the work of intersections in cities every day, through the computer monitors the central and surveillance cameras, and by presenting the proportion of traffic congestion in the arms of all intersections and make the necessary coordination with the operating room in case of accidents or vehicles of order, and will exploit the information that the system by giving it all Hang on signal, which facilitates maintenance and reduces costs. There is a close relationship between the engineers operating the center and team maintenance work, where they cooperate on the quick fix for crashes and breakdowns in particular lines of communication devices and files Ala_i_arip.

The sources added that this system, when implemented, will contribute to the coordination between the contractors of road projects and engineers design and implementation of traffic signals and the control center, where the system has the ability to keep up with traffic volume increasing over the past years and to reduce traffic congestion on the road network and conduct in a flexible and streamlined.

Be noted that this new system, which is a quantum leap and Technology enormous comes after studies showed the field and academia, that the solutions traditional engineering is not enough to reduce traffic congestion and traffic accidents and tremendous speed, in order to improve the level of traffic safety in the cities and regions of Saudi Arabia different, and that they must to activate the role of information and exploitation, analysis automatically using the systems and advanced technologies, especially the transport systems and the Intelligent Transportation that have been applied effectively in most developed countries, as these regulations take into account not only the existing road network, but also the users of the roads and surrounding environmental conditions.

In developed countries use the Intelligent Transportation Systems information technology, communications and control to help operators and users of road networks, as well as the rail to take the best decisions and actions related to reducing traffic congestion and improve the operational capacity of the road network, and increase the level of traffic safety and dealing with traffic accidents in real time, is also used Intelligent Transportation Systems information technology and communications to guide road users to the best tracks, which cut travel time and guide drivers to alternative routes in cases of congestion and emergency situations.

It also works to regulate the movement of public transport such as buses, trains, etc., and collect fees for vehicles electronically if applied to certain roads, provide information on the weather if there is fog or rain or snow, and the reduction of environmental pollution such as air pollution in crowded cities, coordination between the Kalpldiat on traffic, police and civil defense, public transportation, transport companies and other relevant institutions immediately and electronically.
