The increasing traffic volume at most intersections has arose several problems such as road accidents, congestions and conflicts. These problems can well be solved by the design and implementation of efficient traffic signal controls at these intersections for continuous, smooth and efficient movement of vehicles through the intersections. According to traffic signal, signal timing is very important. It is used to propose a suitable green time for the traffic light to be provided at an intersection. Also it is used to determine how long the pedestrian walk signal to be provided will last for. Traffic volume studies are to be made to determine the number, movements and classification of vehicles at a given location. These data is used

Even before motor vehicles, police had to keep the mov ement of horse drawn vehicles, str eetcars and pedestrians safe and orderly. Typical traffic control was provided by police officers who wore white gloves and blew whistles. In 1868 illumi nated traffic signal was installed in Lo ndon near the Houses of Parliament. It was designed to aid the traffic policeman there, par ticularly during hours of darkness when visib ility was poor. The device had semapho re arms to signal drivers and pede strians during the day and it had red and green lenses illu minated by gas for viewing at night. The police offi cer would turn the signal 90 degrees to position the semaphore arms and the coloured lenses towa rds traffic as needed. This was the first recor ded use of illuminated red and green colours to control tr affic. Unfortu nately the device exploded in January of 1869, injuring the poli ceman that was operating it. This partic ular idea was not tried again.
US Patents for tr affic control devices date back as early as 1909. Most of these devices involved semaphores or arrows to dire ct traffic, however a few included some kind of illuminatio n source and lens systems that were similar to those used by the
A simple Google search will turn up hundreds of studies based on the effectiveness of emergency lighting on the road. Obviously, this wealth of information is too vast to summarize in one article; however, there is one study that sticks out when discussing whether red or blue emergency vehicle lights are easier to see on the road. In this article, we will go over a study released by Lt. James D. Wells Jr. on behalf of the Florida Highway Patrol. This study was released in 2004 and concentrates mainly on emergency lighting configurations and the effectiveness of these lights in helping to reduce collisions on the road and keeping officers and emergency first responders safer on the road.
In Houston, Texas alone there are around one hundred stoplights. Recently, a law has been drafted to place cameras on the stoplights and Houston and the surrounding suburbs. These "red-light cameras" or RLCs as they are called automatically take a picture of a vehicle breaking the law by running the stoplight and sends the owner a seventy-five dollar ticket. This method of ticketing is incredibly inefficient and should be removed. The camera system fails to notify the recipients of the tickets in a fair amount of time, does not take into account if the owner is driving, and according to the people of Houston should not even be in place. The current system that the red-light cameras are under is flawed and should be removed completely.
Morgan did not let prejudice against him stop his efforts to invent devices to make the world a safer place. In 1920, the use of the automobiles increased, causing traffic congestion in many of the large U.S. cities. In 1923, Morgan designed and patented a traffic signal (patent #1,475,024). The signal consisted of a tall post with movable arms that monitored and controlled traffic. The post rotated and the arms moved up. The signal contained lights that flashed the words ”stop” and “go.
commuters waste 38 hours per year stuck in traffic. In Washington D.C. and Los Angeles, the situation is even more serious with drivers squandering 67 and 61 hours, respectively, staring at the license plate of the stationary vehicle in front of them” (Keeping, n.d.). Henceforth, it is my speculation that a negative response to the issue of car congestion will generate some serious consequences for the foreseeable future. It is my prediction that a refusal to resolve this dilemma, will spawn complete chaos and anarchy upon the globes highways and byways. Therefore, it is vital that some type of action is taken beforehand in order to alleviate this issue before it gets out of hand. By and large, this final phase of this paper drives this assignment to its conclusion. Ergo, the ensuing portion of this case assignment will elaborate on highlights of this
Problem solving skills are a key element of productive group work. Problem solving skills are not given by nature; these skills are a result of hard work and training. Structured problem solving techniques are very effective way of solving the problem. This technique allows teams to learn how to figure out solutions to the problems (3 ). The three most common methods developed to improve problem solving in groups are the Standard Agenda, the Functional perspective, and Single Question format. In this paper we will cover the Standard Agenda methods as a problem solving procedure (1).
...e to be updated to consider who stopped first and has enough time passed to try and go across the intersection. In the event that all 4 cars at the intersection are self-driving cars, then it may be easier to handle this situation because the cars could have the ability to communicate with each other and decide faster.
3.) Defense, was there enough light from the moon to see someone on the dock?
Traffic Control System was then and is now operating on World War II era technology with most
Traffic engineers and planners need information about traffic. They need information to design and manage road and traffic system. They use the information for planning and designing traffic facilities, selecting geometric standards, economic analysis and determination of priorities. They use this to justify warrant of traffic control devices such as signs, traffic signals, pavement markings, school and pedestrian crossings. The also use this information to study the effectiveness of introduced schemes, diagnosing given situations and finding appropriate solutions, forecasting the effects of projected strategies, calibrating and validating traffic models.
“Each light has a different preset wavelength designed to detect hair, fibers, and body fluids at crime scenes, these lights allow a crime scene to be processed faster and more thoroughly than ever before.” This technology is speedy and can help locate the whereabouts of criminals. The use of in-car camera systems has become very popular, especially by law enforcement. These cameras are used to record traffic stops and road violations of civilians. “From the time the first in-car cameras were installed to document roadside impaired-driving sobriety tests, the cameras have captured both intended and unintended video footage that has established their value. Most video recordings have resulted in convictions; many provide an expedited means to resolve citizen complaints, exonerate officers from accusations, and serve as police training videos.” Photo enforcement systems helps to maintain road safety by “automatically generating red light violations and/or speeding summons and as a result to greatly improve safety for the motoring public.” (Schultz,
Traffic jam is one of the most serious problems of urbanization, almost all the modern cities are facing different levels of traffic jam problems. In general, people can ease the traffic jam and not compromise the quality of life by a policy of sustainable development in two aspects including formulating a more efficient transport pattern and changing the urban construction.
Traffic control establishes a set of rules and regulations that people rely on to help avoid collisions and other hazards. With almost 160 million motorists and 3.8 million miles of public roads in the United States, traffic control on the highways is an important aspect of daily life. Without the control of speed there would be more fatalities than we already have now. Speed limits should be obeyed. A motorist going too slow could cause an accident. When everyone is traveling at the speed limit, a car comes up going 40 mph; if you break everyone will, too, perhaps causing a collision. Motorists depend on traffic control to avoid collisions and travel safely to their destination.
We all use vehicles for transportation. People usually go to their desired destination either by driving their own cars or traveling in public transportation. Actually, it might be tough to choose that which one is the best selection for people to travel. Many people choose one of them according to their comfort while traveling and both of them have advantages and disadvantages in different conditions. Public transportation and driving own car both shares differences and similarities in many aspects, such as facility, cost, and comfort as well as traffic jam and accident occurrence.
It is important to follow all traffic laws to keep everyone safe on road. The amount of traffic accidents and losses drops significantly when people are obeying the rules on the road. Sometimes we forget what a big responsibility it is to drive carefully. Traffic laws are designed to protect you and other drivers on the streets. If we don’t follow them we are not only putting ourselves in risk but also other innocent people. By knowing the rules of the road, practicing good driving skills, you help play a vital role in preventing a crash. You will also be making the safety policies more effective. Many components play a major role in road safety including speed limits that are posted and making sure safety equipment is properly installed and used.
Traffic congestion, is one of the major problems faced in the capitals and major cities in most countries. As with the increase in the growth rate, comes the growing demand for the use of transportation. This works with the response to the needs of the community.
