Traffic technology systems by Nettropolis AG are used to meet the customers' requirements and to ensure a smooth cooperation. With the so-called workflow component, faults can be managed and rectified. Additional modules are used in a large number of operating divisions of the transport companies. [ABSTRACT FROM AUTHOR]

Abstract: In this paper we introduce a novel approach, relying on intelligent engineering, whereby the maximum speed limit at which vehicles on the road can cruise is controlled from some central or distributed facility. The system, as designed, leverages the use of the ubiquitous cellular infrastructure to cut down the costs involved that would otherwise accrue as a result of the need to build a dedicated traffic control system. In the new system maximum speed limits are transmitted from a Central Control Facility (CCF) to all stretches of roads and highways dispersed across urban areas in a highly dynamic manner. The system uses information arriving via a dynamic feedback system on prevailing weather conditions, road conditions, and bulk of traffic, amongst others, before it would broadcast maximum speed limit information to various destinations. When deployed in its final release, this will be done using a highly automated system with little human intervention. The work presented in this paper elaborates the TTC Network Design and RSU Network Distribution for the Tele-Traffic Speed Control System, to remotely manage, enforce, and control the maximum speed limit allowed on road stretches in rural and urban areas for different vehicle categories. The new system has been deployed successfully in a laboratory controlled environment on three vehicle categories; one category representing passenger vehicles, another buses and commuter transport, while the third representing trucks and freight traffic. It is expected that when the system is fully deployed on the wireless infrastructure, speed-related traffic accidents will witness a drop by more than 65–70% according to known accident statistics.

This article focuses on experiments with controlling traffic flow in towns like Ipswich, England, throughout Europe. Traffic planner Hans Monderman argues his 'Shared Space' program makes the driver more alert. The removal of all driving instruction devices including stop lights, painted lines and speed bumps have reportedly done well, forcing drivers to behave more responsibly while on the road.

At around 6 p.m. on May 20, 1995, Alexander Flax had just eased his Toyota Corolla through an intersection in downtown Washington when the tail car of a Secret Service motorcade ran a red light and slammed into him. Washington, D.C., traffic regulations and United States Secret Service policy required vehicles in the front and rear of presidential motorcades to proceed through intersections with their lights flashing and sirens blaring. But several uniformed officers say that former President Clinton didn't like the sirens and the lights and often yelled at motorcade agents who insisted on using them. Acceding to the president's wishes, Secret Service executives told lead motorcade agents not to use the lights and sirens but to stop at red lights. Some agents disregarded that option as a security risk, and the issue became a source of tension among officers and agents, sources say, because no one knew what to do from day to day. Flax's attorneys filed a claim with the U.S. attorney's office with regards to his injuries as a result of the motorcade accident.

In this article, the author discusses driving in Los Angeles, California. It mentions the data by traffic engineering firm Inrix on gridlock and traffic jams in Los Angeles during 2015. It discusses author experience of using public transit, hiring bikes and paying of strangers for rides. It also discusses the need of traffic engineering.

This article states that the Beijing Municipal Government has started soliciting public opinions for a proposal designed to address the city's traffic problems. The public opinion is expected to impact the final plan even though the proposal has already been approved by the State Council. The government plans to levy traffic congestion charge in areas where traffic is heavy in addition to bans on Beijing car owners from driving one day each week based on the last digit of their license plates. The plan also include different parking fees.

The authors offer opinions on traffic regulations. Laws in several Canadian provinces banning the use of hand-held cell phones by automobile drivers are criticized as inadequate. Research on cell phone use is cited in support of the contention that hands-free cell phones offer no increase in safety for drivers.

The article presents a discussion on the extension of the vehicle restrictions in Beijing, China, from April 11, 2009 to April 10, 2010. According to one reader, owners of automobiles will be forced to take taxis once a week, and will have to spend about 1,000 yuan on taxis and endure all the inconveniences caused by the ban. Another reader stated that restrictions of this kind may help ease the traffic and reduce exhaust emissions, but will result in more cars.

The article reports on an announcement by U.S. Secretary of Transportation Mary Peters that Los Angeles, California will receive $210 million in federal funds to help reduce traffic congestion and provide better bus transit services. According to Peters, the funding will allow local leaders to move forward with a plan to convert existing high-occupancy vehicle (HOV) lanes to high-occupancy toll (HOT) lanes and implement congestion pricing to improve traffic, air quality and quality of life in southern California.

This article reviews the actual traffic prediction software from Inrix.

The article reflects on the relationship between law and culture in Italy. Such curious intertwining of two distinct concepts may sound bizarre, but not in Italy, a country trying be at par with European standards, albeit under legislation passed by a political class enamored with continuing scandals. In 1992, this political class passed a law designed to harmonize Italian traffic laws with the standards. The law imposes a speed limit of 130 kilometers per hour on the autostradas, the two dozen limited-access highways that encompass the country.

The article reports that several states including Idaho, Kansas and Missouri have followed Minnesota's lead in the passage of a law that allows bicycles and motorcycles to proceed through stoplights if the traffic control signal does not detect their presence. Other states include Oklahoma, South Carolina, Tennessee, Virginia and Wisconsin. The law implemented in North Carolina reportedly covers only motorcycles.

The author reflects on the importance of color coding on direction signs helping to solve highway hodgepodge. He argues that the U.S. is becoming acutely conscious of the need for a vast speed-up in modern highway construction. He suggests that this color guide should be of considerable benefit even to the extent of employing secondary routes for the purpose of relieving traffic congestion.
