Traffic calming measures are quite common in modern society. Traffic calming measures are physical design techniques that encourage or force motorists to drive slow and constant speed. They prevent speeding and can increase overall road safety. Traffic calming can also make streets more accessible and livable for other users such as pedestrians, cyclists and nearby residents. The main purpose of traffic calming measures is to reduce speed and create a safer traffic environment. Road bumps are one type of measures that is frequently used to reduce speed in residential areas. Traffic calming measures have to adapt to the specific condition of each location but in principle only one design of road bumps is needed. This design should lead to a comfortable crossing at speed lower than 15-20 km/h but as soon the speed increased it should be more uncomfortable to cross the road bumps. The design of ideal road bumps would make drivers hold their speed below 25 km/h at least when crossing a road bumps. Figure 1.1 describe roughly how road bumps influence crossing speed. The designs of road bumps influences experienced driving comfort and through that drivers speed. If a road bump is designed in a way so that the driving discomfort does not increase very much as the speed increases, driver see no reason to slow down before crossing a road bump. In many cases, drivers estimate the discomfort of crossing against decrease travel time. Drivers are prepared to experience more discomfort if it will decrease their travel time, at least to some level. Road bumps are installed in different environments, on streets that have different characteristics. Car parking, interaction with vulnerable road users and other things that make up the character o... ... middle of paper ... ...over entire streets, the layout design or spacing of speed bumps. Previous research from several countries suggests that to achieve overall speeds of 25 to 30 km/h, speed bumps should be placed between 40 and 60 meters apart. Greater spacing, up to 100 meters, can be used for speeds of 50 km/h. Bump spacing can be increased with the presence of additional traffic calming measures. 1.3.6. MATERIALS, MARKING AND SIGNAGE:- Speed bumps with all speed reducing measures, should be highly visible to warn drivers to lower speeds and avoid vehicle damage or loss of control. This essentially eliminates the potential for any legal liability on the part of the public road authority. Most countries have developed special signs and markings for their peed bump installations, and pre-warnings, design speed signs, contrasting materials and protective bollards are usually employed.

Drivers who speed often do not realize the enormous danger they are creating. When someone is speeding they have a higher braking time and are often going too fast to notice all of their surroundings, and fail to take all of the safety precautions a driver should use. Road conditions play a large role in the effects of speeding. Choosing to speed can also get a person’s license taken away, cost a fortune, or both.

Speed limits are designated for roads based on the roads characteristics such as its geometry and capacity, and traffic characteristics such as overall volume, hourly volume and traffic density. Speed limits are designed to most effectively and safely regulate traffic.
From first-hand experience, one should easily realize that the common man would feel negativity toward raising speed limits. People fall into this trap because the general public is often mislead into believing that abolishing speed limits on highways will only cause more harm than good. People often are the victims of misunderstanding and people rarely observe the advantages offered by increasing the speed limit to a safe level.
Some would say that speed limits are not adequate, or certain laws should be changed. Reports have shown that the majority of Americans have no problem with speed limits or the laws; new drivers are not helping either. There are key things that are liable for joining or causing road rage. For example; loud music, honking the horn, tailgating, and changing lanes without signaling all have been known to increase tension while driving. The actual causes can be traced back to different forms of stress. Such as being called into the boss' office for discussion of work performance, making bad grades in school, or having just been dumped by your girlfriend/boyfriend. Road rage is a result of an outburst of all the stress in ones life. Cars are a status symbol in our time. Nice cars give others the impression that the driver has money. Fast or flashy cars give an impression
Nissan Motor Corporation is the automaker that seems to be the leader in safety technology. They implemented many features such as intelligent cruise control and advanced rear-view backup cameras to their vehicles. “The low-speed following mode operates at speeds under about 40 km/h to maintain an appropriate following distance in congested traffic, thereby helping reduce the driver’s workload” (Nissan 7). A teenager may get stressed out when trying to drive in high-traffic situations. Nissan is helping them by using an intelligent cruise control that will slow down and speed up traffic while staying a distance away from the driver in front of them.
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.
Speed limits are necessary for many reasons, for example, safety precautions in town and out of town. Highway speed limits are necessary in order to maintain a reasonable speed and take action when wildlife suddenly appear, or when construction is taking place. In town speed limits are necessary for things such asorder and safety of pedestrians. Speed limits are a way of ensuring a safe environment for people inside and outside of a moving vehicle. The necessity of speed limits has and always will be needed.
Firstly what are some of the causes of urban highway congestion? Rush hour traffic is one of the leading contributors of highway congestion. It isn’t our imagination. Every year commute times to work take longer and longer. Since 1986 car travel has increased almost 40%, while highway capacity has barley grown. As a result most major interstate routes in Metropolitan areas are jammed during rush hours. Grid locked cost Americans almost the equivalent of $51 billion a year in lost wages and wasted fuel. And the situation is only going to get worse. (Steisand, Betsy. 1996). What causes rush hour traffic? Simply put, at specific times of the day be it in the morning or evening motorists in general are either on their way to work or home. There is such a glut of vehicles on the expressways at this time. They all need to get to their destinations at peak times of the day. It is a simple equation: Too many cars incorp...
“The one thing that unites all human beings, regardless of age, gender, religion, economic status, or ethnic background, is that, deep down inside, we all believe that we are above-average drivers” -Dave Barry, comedian. The number of accidents over the last ten years have drastically increased, drivers are paying less attention to the road itself. Many individuals behind the wheel of a car believe that their driving does not affect the road conditions, however it always will. The driving habits of today are catastrophic due to the reasoning that the driving will affect other lives through reckless or distracted driving, and disobeying traffic laws.
Traffic lights are signaling devices located at road intersections and pedestrian crossings, they are now part of our everyday life. Before traffic lights were invented, policeman would control traffic, but accidents would still occur frequently. This is when J.P Knight took action in 1868 and made the first traffic light. It was installed outside the British Houses Of Parliament but didn’t last long since it exploded in 1869 due to a gas leak. It was only in 1912 that a man named Lester Wire created an electrical traffic light that is still used today. There are three main types of traffic lights: fixed timed, semi actuated and fully actuated. Fixed time traffic light are light where “signals change according to a pre-set timing. The signals will cycle all the time even if there is no vehicle or pedestrian demand.” (a). In semi actuated signals vehicle detectors and push buttons are installed on streets and roads. The traffic signals will remain green until either a group of vehicles is detected or a pedestrian pushes a button. Lastly in fully actuated lights “ signals are programmed to change with minimum green times depending on the traffic and pedestrian demand on all approaches. The signals will change based on the demand from each approach.” (b).
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.
Road safety is one of the most important aspects of daily living. Our vehicle is our main transportation from one place to another. The number of car and motorcycle accidents seem to be increasing because of the many distractions, the lack of safety measures and judgment to road conditions and weather. Not being cautious increases the chances of not only injuring ourselves but hurting others as well. On the road, you see people talking on their cell phones or texting, eating, putting makeup on, changing the radio station, reading or using your GPS while driving. These are all distractions that endanger drivers, passengers and bystanders safety. Safe driving involves off-road precautionary measures such as making sure tires are properly inflated, testing windshield wipers, getting regular oil changes and tune-ups and adjusting the mirrors. All of these actions can help prevent an accident. Unfortunately, not all of us decide to wear our seat belts when driving or turn signal ligh...
