...Traffic Modeling Paper Concepts of math can be displayed and solved in many different ways. There are equations, graphs, and word problems and several concepts that can be used as examples to help solve mathematical issues. In week four of this College Algebra class Learning Team B was present with an assignment involving a traffic model. The traffic model is the key to helping Learning Team B solve the problems the assignment presents. The traffic model represents a number of cars within the area at any given time represented by letters. Learning team B must solve questions based on this model. There are several equations that were made in order to prove that the numbers of cars entering and leaving each intersection must be equal to keep traffic moving smoothly. Variables f and g are independent variables. This means that variables a through e are dependent on variables f and g. The number of cars at intersection a depends on how many cars turn from intersection f. The number of cars at intersection b depends on how many cars turn right from intersections f and g. This tells you that there are infinitely many solutions since the number of cars that turn onto Elm from Oak, Pine, and Aspen vary. Similarly the number of cars that turn onto Maple from Oak, Pine, and Aspen also vary. To list two acceptable traffic flows first let variable f be equal to 365 cars/hr and let variable g be equal to 400 cars/hr. Variable a would be equal to 850-365, which equals 485 cars/hr. Variable...

...Influence of Visual Media Paper Carolyn R. Slaughter HUM/176 October 6, 2013 Dr. Steven H. Mathew Influence of Visual Media Paper What would this world be without the influence of visual media? People want to see what is going on in the world around them. In the United States people want to watch TV and it has a great influence on culture experiences. People want to keep up with the latest celebrity gossip, and political pros and cons. In today’s society visual media is used in new ways, at one time people were only able to watch TV in their homes, now it’s available on digital televisions, DVD, smartphones, tablets, and computers. At one time there were only three major broadcasting networks available (ABC, NBC, and CBS) for viewing primetime movies and shows in America. These networks would appeal to a general family audience. (Lule, 2012) Visual media is an important aspect in many people lives; it provides entertainment for many people. The entertainment media has shaped the American culture and its values in many different ways. Today the young as well as the old try to mimic what they see celebrities do. If Miley Cyrus Twerked on a YouTube video, and her fans went insane over the video, now the young people who are her fans wants to do the Twerk dance in spite of how ridiculous some may view it as being. Parent have to preview the content their children are watching on TV whether it be in movies, videos, or music. After viewing the video on YouTube it is easy...

...An Application Involving Traffic Modeling According to Blitzer (2009), checkpoint four "shows a system of four one-way streets" (p. 573). The numbers in the figure denote the number of cars per minute that travel in the direction shown. a. Use the requirement that the number of cars entering each of the intersections per minute must equal the number of cars leaving per minute to set up a system of equations in w, x, y, and z. For Intersection I1: Because 5+10=15 cars enter and w+z cars leave the intersection I1, then w+z=15. For Intersection I2: Because w+x cars enter the intersection and 10+20=30 cars leave, then w+x=30. For Intersection I3: Because 15+30=45 cars enter the intersection and x+y cars leave, then x+y=45. For Intersection I4: Because y+z cars enter the intersection and 10+20=30 cars leave. traffic will keep flowing if y+z=30. Arrange the equations where the variables are on one side and the constants are on the other side of the equal sign. w+z=15 w+x=30 x+y=45 y+z=30 System of equations: w+z=15 w+x=30 x+y=45 y+z=30 b. Use Gaussian elimination to solve the system. System of equations: w+z=15 w+x=30 x+y=45 y+z=30 Put system of equations in matrix form. w x y z 1 0 0 1 15 1 1 0 0 30 0 1 1 0 45 0 0 1 1 30 Solve the system of equations. -1R1+R2 -1R2+R3 -1R3+R4 w x y z 1 0 0 1 15 0 1 0 -1 15 0 0 1 1 30 0 0 0 0 0 w+z=15 x-z=15 y+z=30 The last...

...concerns caused by the increase in vehicle usage include pedestrian safety, residential livability, and environmental deterioration. I have decided to explore this question by considering features that have both affected urban form and also acted as planning measures to limit negative social and environmental impacts, these include motorway developments, the garden city urban planning approach and Greenbelts. With over 15 million units of Ford Motor T sold between 1908 and 1927 (Flink, 2001), urban form was most dramatically influenced in American cities during the correlating time period. Planners began to oppose the conventional Roman-grid layouts, where streets were arranged at perpendicular angles to each other. Rising traffic congestion at intersections placed pressure on city planners to reorganise the structural layout in attempts to liberate these chaotic streets. Pedestrians were heavily victimised by the automobile’s rise as modern highway codes and road systems had not yet been established. “Pedestrians crossed the streets whenever and wherever they chose” (Brown, 2006) and coupled with the fact that automobiles had high-speed potentials; together, this created a dangerous environment for city residents especially in Britain with increasing road accidents (Plowden, 1973; see table 1)....

...is based on the most happening concern of Dhaka city- Traffic congestion. Dhaka, the capital city of Bangladesh is burdened with many different problems, namely housing problem, sanitation problem and problem related to water logging, etc. Yet, among many other problems, the city has been experiencing severe traffic-problem which is a common phenomenon in our daily life. Dhaka city situation is more alarming mainly due to vehicular movement and traffic jam. There are different types of vehicular namely, car, bus, jeep, truck, minibus, microbus, auto-rickshaw, tempo, mini-truck, motorcycles and innumerable numbers of rickshaws. There are many reasons behind traffic jam in Bangladesh. Among them some major factors are as follows: • Undisciplined traffic signal in the road. • Indiscipline among the road user. • Might is right, everybody are free to park their vehicle on Road. • No knowledge of traffic rules which encourage violating the rules. • Enforcement of rules by dishonest persons who are busy in collection of illegal money from traffic rules violators. • Heavy numbers of vehicle on roads. Time is the most valuable things in the twenty first centaury no doubt. And traffic jam is killing the most productive time of the people of Dhaka city. Time is going on and on and we are lagging behind. The world is becoming speedy where as we are becoming slower. To reduce traffic jam we can take steps such as: • Have a good public...

...Reverse round a corner step by step technique The reverse round a corner or left corner reverse as it is sometimes known is one of 4 manoeuvres you will need to learn before taking the driving test. The reverse round a corner manoeuvre is also one of the more common manoeuvres asked by the test examiner for you to perform. This tutorial will demonstrate an ideal technique that the examiner will be looking for in order to pass this part of the driving test. The test examiner will be looking for 3 key skills demonstrated by yourself in order to successfully complete the reverse round a corner manoeuvre. These skills are: • • • Accuracy - The test examiner will be assessing your ability to reverse round the corner, not touching the curb or straying too far onto the other side of the road. Control - The examiner will be judging your ability to keep the car at a slow and stable speed by use of clutch control. Observation. Effective and all round observation must be taken whilst performing the reverse round a corner manoeuvre. Reverse round a corner diagram A During the driving test, the examiner will ask you to park up on the left on many occasions. They are observing your accuracy and safety for parking. Another occasion may be the examiner is going to request you demonstrate the reverse round a corner. The examiner will ask you to park up on the left, just before the turn you are going to reverse into as in diagram A. When the examiner asks you to park ...

...roads remain free from all types of hassels and harrowing happenings. Unless and until the Ministry of Surface Transport, Traffic Regulatory Agencies/Police etc. put road safety under the scanner and devise meaningful and result-oriented ways and means to render road travel a pleasant experience, things would not improve. Strict adherence to traffic rules and regulations is just one of the measures that can bring about perceptible change in the situation. Unfortunately, the series of accidents that occur on Indian roads day in and day out brings home the terrible truth that raising the safety bar on Indian roads remains a pipedream. When the tools of high technology are readily available and there is no shortage of funds, it is not comprehensible why this vital area of transport, both goods and humans, remains vulnerable to accidents. Ironically, while new roads are being built, and newer, supposedly safer automobiles— with safety features like airbags, crash sensors etc—race out of the factories, the country’s road safety record remains abysmal. No doubt, several factors contribute to the appalling statistics that tell the sorry state of affairs on roads. In India, this is particularly true since the facilities available for non-motorised users are poor or even non-existent. It is high time the authorities did more than indulge in “traffic drives” to book errant drivers. Only a zero tolerance policy on a sustained basis to educate people on good road sense will...

...that was right in the middle of town. It caught on fire and burnt down about 6 months ago. They are rebuilding but the building now is a lot bigger than the previous one. That being said, I don’t feel there needs to be another big building right behind it, right in the middle of town. It will completely change the landscape of the town. People come to Wimberley for the tourist experience. Not for the big town experience. They can stay home for that. There are two roads on either side of the land where they want to build. They are two lane roads. The town put in really nice sidewalks a few years ago. Where are they going to expand the roads to accommodate the amount of traffic that will be coming? They have Market Days on the first Saturday of the month. That day is a good indication of the amount of traffic we will get on a daily basis. The camp that is happy about HEB coming thinks that it will be competition for Brookshire Bros. and then BB will have to lower their prices. I’ve even heard some people say that hopefully it will put Brookshire Brothers out of business. These people can’t see the big picture. Let me ask a question. Who is HEB’s biggest competitor? Walmart. What does Walmart like to do? Come into small towns and take over big empty buildings. Then what happens? They start putting small town Mom and Pop stores out of business. Do we want that to happen? I know I don’t. I don’t believe that this will be a good thing, HEB coming into my small town. I’m not...

...unlearn much of what he has learned in his own State and to learn a lot that is strange to him. This produces irritation – or worse - in the motor owner and motor driver, and tends to unnecessary costs of traffic administration (which the motorist usually has to pay for). It also adds to traffic dangers through ignorance or unfamiliarity with local conditions or practices on the part of drivers. Therefore, anything that can be done to lay down a national basis for motor traffic control must be of much practical value. Commonsense suggests that there should be uniformity instead of variety, and that the growing volume of interstate traffic requires a national instead of a local viewpoint in things common to traffic in all of the States. Were all motor vehicles kept within their own State boundaries, little disadvantage would arise from the present welter of confusing motor legislation, but when a system becomes national, a system (or lack of system) of arbitrarily fixed laws that differ substantially in matters in which there should be common agreement appears absurd, if not intolerable. I do not consider that it would be very difficult, once the groundwork had been prepared, to induce the various State Governments to agree to a national conference of traffic authorities and representatives of the recognised motoring organisations in the...

...How distractions will affect the driving? There are many factors which can distract a driver on the road. Distracted driving can occur any time a driver's attention is taken away from where they should be focusing their concentration - the driving task. There are many different types of distractions, both inside and outside the car. A physical distraction causes you to take your hands off the wheel, such as eating a sandwich. A mental distraction takes your mind away from the road, such as speaking with a passenger. Mental distractions may be more difficult to identify, as we often take discussions with passengers to be a “normal” part of driving. “Driver distractions include cell phones, eating, drinking, changing a CD, fiddling with radio dials, talking to a passenger, experiencing emotional distress, minding children, personal grooming, looking at billboards or even other vehicles on the road” (CAA, 2012). A lot can happen when a driver is distracted. For example, there is a significant increase in driving with no hands on the wheel, not watching the road, sudden braking and wandering into other lanes which can result in lack of focus on the road, increase the chances of collisions and a hazard to pedestrians, yourself and other road users. I personally witnessed drivers on an everyday basis being distracted while driving on the road. For example, many would be texting or making a phone call, some will be looking somewhere...

...8/9/2014 Prof. Karanja Week 10 Ch. 8 Ex. 5 An example of a good Six Sigma project would be discovering ways to improve traffic safety in my neighborhood. In the Ardwick-Ardmore district of Landover, Maryland, there are many problems with traffic patterns in the neighborhood. The main backbone, which is Ardwick-Ardmore Road is a constant strip of road with no deterrent traffic lights to delegate traffic flow. Turning onto this street from adjacent avenues can be risky due to the right of way that remains with participants traveling on Ardwick-Ardmore Road. By implementing a Six Sigma plan, traffic flow can be improved with changes in the grid plan. DEFINE: The problem at hand is the fact that the constant traffic flow on Ardwick-Ardmore Road can be dangerous to motorists traveling from adjacent roads. MEASURE: Data can be generated by using a survey for passing pedestrians based on their experiences on Ardwick-Ardmore road. Motorists can be selected at random to a timed trial of merging onto Ardwick-Ardmore road from their originated streets from which they traveled. Data results that include collisions, close-calls, and reckless driving will be accepted as valid entries. ANALYZE: Trends can be developed. There may be a possibility that traffic patterns increase during a specific timeframe, etc. IMPROVE: Implement new ideas to deter potential collisions and close-calls based off of the information collected. CONTROL: Continue to track the data input to validate assumptions...

...What Type of Driver Are You? Driving is a task we must take part in on a daily basis, but after several years of driving in frustrating and hectic rush hour traffic one can begin to hate even the thought of going to the grocery store. The roads are filled with very different types of drivers; Competent, Overly Cautious, Distracted, and Reckless are just a few of them. How we determine which category we best fall under can be a challenge, because in our minds we think we are good drivers, but in most cases we’re too oblivious to these classifications. First, there are the rare competent drivers who drive safely by not speeding and obey the common driving laws. Competent drivers are always coming to a full stop, looking both ways, using turn signals, and yielding when necessary. This type of driver is the most agreeable of the bunch, putting others at no risk. More of them on the road and the world would be a better place. We tend to think of bad drivers as the ones who charge down the road, wrecking everything in their path, but is it just as bad to be too cautious? Second to the competent, are the overly cautious drivers. They seem to be the ones to cause traffic jams and frustrate other drivers, because they are so indecisive and unpredictable. You know the kind - won't speed up to merge and stops at the end of on-ramps, sits helplessly at a four-way stop because they don't know what to do, slams on the brakes for no apparent reason, and, of course, refusing to exceed the...
