What is operations research? Operations research is the application of the methods of science to complex problems arising in the direction and management of large systems of men, machines material, and money in industry, business, government and defense. The distinctive approach is to develop a scientific model of the system, incorporating measurements of factors such as chance and risk, with which to predict and compare the outcomes of alternative decisions, strategies or controls. The purpose is to help management determine its policy and actions scientifically. (Ravindran, Phillips and Solberg 1987). How does operations research apply to highway systems inefficiency? Let’s find out!
“Automakers don’t build roads and governments don’t build autos, yet we expect cars and roads to mesh together seamlessly to form a transportation network.” For year’s automakers and regional transportation planners have been working to put information age technology to work solving traffic problems. All over the world people are choosing to travel by automobile because this flexible mode of travel best meets their needs. But grid locked expressways threaten to take the “mobile” out of “automobile.” This presentation will try to show reasons why our expressways are so congested, what the Federal Highway Administration proposals are to alleviate congestion and the advantages and disadvantages of these proposals under review.
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...

Travelling across the country in an old Ford Model T would never be easy; but, traveling in a Model T on a bumpy dirt road with ruts and holes, almost unbearable. Thankfully, many advances in America’s roadway systems came about in the 1900s. Traveling from one city to another became not only quicker and easier, but also safer, thanks to the many innovations that roadways experienced over the last century. Many engineers put in a lot of time and effort to make these innovations and need to be accredited for their scientific achievements. However, getting to the roadway system that we take for granted today did not happen overnight. It took new technology and some brilliant minds to bring the pieces together to form the luxury of nice, smooth
Imagine that your car could detect hazardous roads before you could sense it? A feature that provides this type of protective driving exists within European cars. This valuable safety feature that is offered in European cars i...
Ever since the invention of the automobile, numerous efforts have been employed to try and improve its safety features. Judging by the current statistics, one could argue that driving has so far turned out to be a risky business. In actual fact, people of all ages and social status are considered to be in control of lethal weapons whenever they have to drive. According to the National Safety Council, it is estimated that more than 41,000 people lose their lives in road accidents annually and no less than 2 million more suffer from serious life threatening injuries (2009). Furthermore, it is estimated that at least 50% of the people killed in road accidents is as a result of their failure to adhere to safety measures such as wearing seatbelts while driving, driving under the influence, or careless driving (Ingalls, “Defensive Driving Strategies”). As an effect, huge losses occur with respect to life, injuries sustained, and damage to property.

With the introduction of the automobile in the early 1900s, laws have been instituted to protect drivers on the road. With these laws come lawbreakers who put their agenda in front of the well being of others. Tens of thousands of lives have been lost. billions of dollars have been spent, and pollution has grown exponentially because of this. drivers travelling at high speeds on roads (Hartman).
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.
These days, cars are necessary for everyday living. They take us where we need to go. They are the method of transportation for everyday traveling. Road rage is an increasing problem in America. Incidents of violent driving have been rising for many years now. Many people identify themselves by the car they drive, because of this; road rage is only increased. Potential problems should try to be avoided.
These technologies have made driving an easier and enjoyable experience, as well as reducing our chances of getting into accidents. The research presented in the following article “Driven to Distraction [in car technology]” provided surprising conclusions. Professor John D. Lee from the University of Iowa states the following issue: “Technology is changing very quickly. Many of these things coming into the car were not designed to be used in it. ”(Edwards 8).
For operations management to be successful, the function of the operation must be first be defined. The degree to which this is achieved is a measure of effectiveness, the key objective of operations management. Efficiency is less important since there is no point in which carrying out an irrelevant, or worse damaging, activity effectively. Effectiveness means achieving objectives, efficiency means consuming minimum resources. While both are desirable, the former is of overriding importance.
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.
Consider a scenario: After a long day at work, you are heading to a trip early morning next day and you have errands to complete before you leave for a weeklong vacation to Caribbean and attend a call while driving. With rush hour traffic in Los Angeles, 20 minutes commute is looking like 90 minutes commute.
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.
The development of every nation hinges on the effectiveness of their transportation systems. Movement of goods, services and people to and from locations is made possible by transportation systems. The importance of effective transportation systems cannot be over-emphasized. Many countries face transportation problems and my country Ghana is no exception. A trip of about 30 minutes usually takes about an hour or more due to traffic jams. This is seriously impacting productivity and has become a topical issue in the country. The situation is the same in Uganda where I currently work. To this end, Transportation Engineers are needed to design roads/ highways that will stand the test of time, plan effective traffic management systems to reduce
