‘Traffic congestion is a condition on road networks that occurs as use increases, and is characterized by slower speeds, longer trip times, and increased vehicular queueing. When traffic demand is great enough that the interaction between vehicles slows the speed of the traffic stream, this results in some congestion’ (wikipedia 2014). Nowadays , with the development of our modern life , traffic congestion is getting worse than ever and it soon becomes one of the biggest concern of the world in the twenty-first century.
According to ‘Traffic Congestion and Reliability: Linking Solutions to Problems’ 2013, since 1982, the levels of traffic jams have increased in cities of all cizes leading to many negative impacts on our environment and economy.

This method has shown some possitive achievement in attempt to prevent the levels of traffic jams from rising in recent years. In 2004, the congestion tax system introduced in London resulted in the reduction of traffic levels in city center by 12 per cent, of which from 50 to 60 percent changed into using public transport (Timilsina 2014). By rasing the fee from £5 to £8 for each time privately owned means of transport crossing the cordon around central London in 2005, the percentage of car traffic in the city central of London has decreased by about 20 per cent, the average speed of traffic in the center areas has an increase of 3 miles per hour (from 8 to 11 miles), and both bus and car which are dealyed during peak traffic periods have dropped by even larger proprotion (Becker 2006). Different kinds of taxes are being used in many parts of the world to reduce the levels of traffic congestion and one of them is road pricing. In Florida, 71 per cent of drivers changed the time of their trip at least once in a week due to a discount of 25-cent on 50-cent rush hour toll and in Minneapolis, drivers are allowed to pay a toll to be capable of using speedier high-occupancy vehicles lanes resulting in a 50 percentage reduction in congestion during rush hour along with a decrease of 12% in crashes (Furchtgott-Roth
Q1. Congestions on the roads are a problem for traffic management. What policies will you advocate for reducing congestion on streets and highways? Are congestion charges or building a toll road /bridge a better strategy for addressing this issue? Also, how would you address equity issues in the light of congestion charges implementations? Ch 14
Various aspects of traffic congestion in Toronto have been analyzed in detail. It is clear that Toronto is facing a serious problem of traffic congestion since it is the most congested city in North America. Traffic congestion in Toronto costs over $ 2 billion annually and it is caused by a variety of factors. These factors are categorized into non-recurring and recurring factors. However, the paper focused on recurring factors which contribute to the largest proportion of traffic congestion in Canada. These include increased automobile use, poor planning and lapse in implementation of laws which govern traffic systems. This leads to the use of many private cars by employees who commute to work as opposed to use of public transport systems resulting in congestion. Traffic congestion in Toronto has various adverse effects including barriers to emergency services, delays, idle time and opportunity costs as well as pollution.
Transportation systems are what support the high levels of accumulation and concentration within cities. The bigger the city, the more complex its urban problems are if not properly managed. The largest transportation problems occur when public transportation systems fail to fulfill the many requirements of urban mobility. Urban efficiency is highly dependent on its transportation systems to move consumers, labor, and goods from one point to another. The most outstanding urban transportation issues in the United States are: traffic congestion, longer commuting, inadequacy of public transport, green transportation difficulty, and good distribution (Rodrigue).
Before, The Federal-Aid Highway Act of 1956, there was huge amounts of traffic in urban areas and the ludicrous amounts of traffic disappeared. The goal of the act was “to protect the vital interest of every citizen in a safe and adequate highway system” (National). Not only was the highway system that was created safe and adequate, it made it so almost every driver would reach their destination unscathed and made driving the main form of transportation. The Federal-Aid Highway Act of 1956 far exceeded the expectation of its effects and those positive repercussions are still felt
The Department of Transportation released a report analyzing three different surveys and studies taken in 2011 and 2012. They found that, at any giv...
The most noticeable inconvenience of driving in Miami is traffic congestion. In fact, because the highways are cluttered with a significant amount of vehicles carpooling is encouraged. For this purpose, high-occupancy vehicle (HOV) lanes were formed. Each weekday, a simple twenty-minute drive turns into an eternal wait for forward progress. With each minute that goes by cars advance less than twenty feet. And while the traffic may open up in some areas, in its entirety I-95 remains congested during the morning and evening hours, as seen in the image where cars on the South Florida Highways line up bumper-to-bumper. The cause for such highway clutter varies, but it is interesting to note the difficulty in explaining highway driving conditions. It is uncertain as to whether the accidents cause traffic congestion or the traffic congestion causes accidents. Either way, the main roads and highways commuters take to work are crowded with drivers. Furthermore, I-95 passes through several commercial districts in the lower Miami area. Many large trucks and commercial vehicles, as well as passenger vehicles, drive to work at these commercial areas. The weekday traffic congestions on the Miami roadways are, in large part, a major inconvenience to commuters, all with intent to arrive early to work.
Traffic reduction stems primarily from a decision to drive (Engwight,1992), a
First off, traffic jams became autonomously problematic due to the cramped conditions, and not as prevalent amount of roads. With the increasing amount of people who owned automobiles in inner cities, this is something we see that is just as bad and even worse today. The Great Gatsby
Automobile traffic jams have always been a problem. From the past decade until today, the amount of people driving has increased tremendously, therefore crowding the highways particularly in major cities. Since Atlanta is one of US's most important cities, it is not an exception to the case. Along the next paragraphs I will discuss problems concerning specifically Ga. 400 highway, which I believe is the worst in Atlanta when it comes to automobile traffic.
Some say that one of the main causes of aggressive driving which usually leads to road rage is highway congestion. The road construction on the major interstates adds to
We as a city, need to enforce speeding more, and make changes to slow people down, on roads. Solutions to overcome speeding are key. There have been speeding campaigns in the past, that had been successful. The speed readers on our roads cause people to slow down effectively. We need to have more speed readers on our city’s roads, to encourage people to slow down.
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.
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.
OTA stated that based on current trends in population and travel … the number of vehicle-miles traveled (VMT) nationwide is projected to increase by 2 to 3 percent per year from now through 2005, resulting in a cumulative increase of about 40 to 60 percent. Obviously, VMT growth could have a major impact on traffic flow in urban areas, as well as on air pollution (84).
