...SPEED ZONE STUDY March 14, 2013 INTRODUCTION Recently in many areas of the State of Texas the speed limit has been changed. While some areas have remained at the 70 mph limit that many drivers have become accustom to, other areas have seen increases from 75 mph up to 85 mph. But, what effect does this have on drivers that travel between these areas with varying speed limits? This study is being conducted to determine what these changes in speed limits have on drivers. With the current speed limit of 70 mph, how fast do driver truly drive? And given the average speed it is the goal of this study to determine if drivers will increase their speeds proportionally in the new high speed zones. While there is much debate on the speed limits and the effects it has on drivers, this study will serve to provide an accurate study on whether or not driver actually pay any attention to the posted speed limits. In addition the driving habits of today’s driver will be examined in relation to posted speed limits on many of the Texas highways. ABSTRACT The Speed Zone Study will be conducted in an effort to better understand how the recent changes in the posted speed limit affect drivers on those highways. To better understand how these changes affect drivers this study will monitor traffic in areas with different speed limits. The goal is to determine if driver adhere to the posted speed limit or if drivers exceed the posted speed limit. If drivers exceed the posted speed limit...

...Rider Library Catalog Publications Better Mousetraps Simplified spot speed studies Editor’s note This article is the first of five summaries of traffic studies described in the Handbook of Simplified Practice for Traffic Studies: (1) spot speeds, (2) traffic volumes, (3) sight distances, (4) crash analyses, and (5) school zone programs. The handbook was developed by CTRE and funded by the Iowa Highway Research Board (TR455). The handbook describes straightforward trafficstudy procedures to help local agencies “get their arms” around specific traffic-related questions or potential problems. Data collected from these studies can be critical to decision making and can help agencies communicate more effectively with community members and local officials. All procedures outlined in the handbook and described below follow national standards. Figure 1. Example stopwatch spot speed study layout Figure 2. Example radar meter spot speed study layout Spot speed studies are used primarily to determine the distribution of traffic speeds, or vehicle speed percentiles, at a specific location. These data help traffic engineers determine and/or evaluate traffic operations and traffic control practices at specific locations; establish design elements for roadways, pedestrian walkways, and bikeways; assess roadway safety questions; and make other traffic safety-related analyses. Rules of thumb For spot speed studies, a sample size of at least 50 and preferably 100 vehicles should...

...Road Speed Limits Professor: Kanyo 08/03/2011 Mid-Michigan Community College Abstract Most of nations have their own road speed limits. This is also an argumentative problem in the modern society. A number of people think that it is necessary to use speed limits to protect people because they believe that lower speed limit can decrease fatalities, injuries and property damage. Others believe that we need to change this policy because it cannot correspond with the development of car quality. According to the data from many car manufactures, the technology of vehicles has changed a lot. I think we do not need to maintain the old standard. We should make new policy to accommodate new technology and new society. Lower speed do not means safer and not fast speed means dangers. I am the one who wish government can change this policy because I think that changing the speed limit cannot only save our time but also boost our economy. Road Speed Limits Most of countries have their own speed limit; it is used to regulate the speed of road vehicles. Speed limits may define maximum, minimum or no speed limit and are normally indicated using a traffic sign. Speed limits are commonly set by the legislative bodies of nations or provincial governments and enforced by national or regional police or judicial bodies. The first speed limit legislation was created in the United Kingdom with the Locomotive Acts. Drives are required to control at a safe speed for...

...Neighborhood Speed Control By Charles Russell, 21 May 2011 Thesis: Changing our neighborhood traffic speed so everyone can be safe, when they want to take a walk, jog down the road and or even ride their bikes but most important, protecting their most valuable asset; their children. There is a beautiful upscale Washington DC suburb called “Kingstown” located in Alexandria, VA. This is the area my family and I decided to live about five years ago. We purchase a townhouse located off a street called “Chelsea Search Way” which is a cuddly sac off another street named “Summer Ridge.” This is the main street going through our neighborhood and links many cuddle sacs together. Summer Ridge is like one big loop that turns off of Kingstown Village Parkway and then reconnects after a mile and a half. Summer Ridge is one of the liveliest streets neighborhoods you would ever see. Everywhere you look there are small children playing, people walking their dogs, joggers running and bicyclist’s riding. The only problem with this is that this neighborhood could be one of the most dangerous places because there is a lot of traffic going up and down this road. Each year over 4,000 sons, daughters, mothers & fathers were killed while walking in their neighborhoods or crossing streets. Fairfax County must not understand that there is a problem here, because the speed limit was set at 25 miles per hour, which I believe is way too fast for such a playground. Not only the speed is the problem...

...#54406 Report Connection speed simulations are of great help when determining the best type of connection for your use. There are different types of connections with different speeds and characteristics just as there are different types of users, both at home and at big corporations. The budget they posses is what will determine just how much of a top quality connection they can get. Download Speed = 20kbps Utilization averages about 80% for downloads and about 2% for uploads. The high utilization of 80% does not give much available bandwidth for potential new applications or users. The Response Time is in the range of 5 to 7.5 seconds, too much and too long. This slow connection can get overloaded quite easily and would be ideal for personal use in a home. Download Speed = 40kbps This connection offers twice the speed of the last connection. Its Utilization averages 42% for downloads and about 2% for uploads. It can be seen in the simulation that twice the speed can mean twice as much bandwidth, or as close as it can get to twice as much bandwidth. Even though there are better sources for higher bandwidth, this particular connection is a decent one for a low budget user. In terms of Response Time, this connection ranges from 2.0 to 2.5 seconds. That’s more than twice the response time seen in the 20kbps connection, meaning that this connection can still be overloaded, but will require a more stern use by an equally stern user. Download Speed = 512kbps This DSL connection...

...Do you think the current highway speed limit in Canada is appropriate? How would decide whether or not it should be increased or decreased? Considering Canada has nearly 900,000 kilometers of road, I am a little surprised the topic of speed limit optimization hasn’t been more of a hot topic for government agencies. Canada has a maximum speed limit of 100km/hour on multi-lane highways. For two lane highways, the speed limit remains the same at 100km/hour. In urban areas the speed limit drops to 60km/hour on major roads, and down a further 10 km/hour for a speed limit of 50km/hour in residential areas. As is typical in any country around the world, the speed limit in school and playground areas is reduced further (AngloInfoCanada.Com). If the speed limit were raised, the marginal benefits would be: 1. Reduced travel times 2. Congestion relief 3. Higher productivity of transportation of goods The marginal costs associated with a speed limit increase would be: 1. The cost of more patrol vehicles and police presence 2. Lost revenue from assigned speeding tickets 3. The cost of increased fuel consumption When looking at the marginal benefits, there can be assumptions made on increased productivity, reduced travel times and congestion relief, however there are no real numbers or evidence to support these statements as they are natural assumptions. The current infrastructure in Canada accommodates the number of vehicles on the road, yet there is frustration with congestion...

...length of how long it takes for a sound to flow in a 1 meter-long tube within 5% error. The technique is to record the time of the echo sound made by snapping fingers. A microphone attached to the computer would be placed at the tube’s opening to determine the speed of sound at room temperature. Once the fingers were snapped at the opening, they created the sound, which traveled to the end of the tube back and forth. In addition, the microphone would collect the sound and transfer that information into the computer. After bouncing off from the closed end, the sound would hit the microphone; the computer would displace a graph, which shows the initial sound and the echo. The speed of sound would be determined by using the round-trip time and the length of the tube. Materials & Procedures: The materials that were used in this experiment were: * Computer * Vernier computer interface * Logger Pro * Vernier Microphone * finger * 1 meter-long PVC tube closed at one end * Thermometer * meter stick The experiment started with measuring the room temperature. The Vernier Microphone was attached to Channel 1 of the interface. The graph of sound level vs. time was observed in the file “33 Speed of Sound” in the Physics with Vernier folder.. The microphone was placed at the tube’s opening to detect both the initial sounds and echo. A student was tasked to click ‘collect’ to start data collecting when another student snapped the fingers to make the...

...Question: Critically analyse HR planning and develop a recruitment and selection plan for the UK High Speed Railway Project. 1.0 Introduction Within this report, the main influential factors which effect the development and construction of the High Speed Rail Project (HSR), will be identified and explored. Because approximately 20 per cent of all budgeted spending for transport in the UK between now and 2021 is allocated for HSR, strong human recourses and a robust recruitment and selection plan are vital to its success, (gov.uk, 2013). This essay will analyse the strengths of existing HR strategies and choose suitable methods for recruitment, in the context of a large scale, long term national, government backed project. The key decisions will centre round union relations, agency recruitment versus long term employment contracts, potential of hiring from within existing similar industries and taking on employees new to the industry. This essentially pits useful experience of industry employees against employees with fresh perspectives to influence a change in culture, from other railway companies. The findings of this essay will be applicable to the actual HSR project as all theory and studies used within, are based on academic sources. This essay is structured to firstly explore the landscape surrounding this project and human recourse issues in general, before presenting conclusions. 2.0 Development In order to identify the main issues associated with...

However, often the technological developments are working in the benefit of humankind evolution, but in the detriment of the nature. High-speed rails are a model of such solutions, meant to improve humans’ lives. Their high speeds (between 200 and 431 km/hour), and their easy boarding (the time spent in boarding is less than 30 minutes, depending on the travelling class), transform the meaning of travelling, making it a real experience. Moreover, the high-speed rails lead to indirect benefits such as allowing the possibility to travel for business purposes, or to working relocation. On the other hand, indirectly, high-speed rails create negative outcomes: urban agglomerations because of this efficient transportation mode, automatically lead to people deserting the rural regions, for...

...Running head: NEUTRINO PARTICLES 1 Neutrino Particles Found to Break the Speed of Light Andrew Alexander Cuesta Lynn University NEUTRINO PARTICLES 2 Neutrino Particles Found to Break the Speed of Light Recently, a discovery that may revolutionize modern science was made in Europe. Modern age technologies have allowed for scientists to experiment through trial and error their most desired curiosities. Throughout history man has immensely improved his capability of speed and longed to reach the greatest velocity in the universe, the speed of light! Researchers and Scientist working for OPERA (Oscillation Project with Emulsion-Racking Apparatus) recorded particles traveling faster than the speed of light of 299,792,458 meters per second. These ghostly subatomic particles are what scientist call neutrinos and they were evidently recorded traveling at 299,798,454 meters per second, which is faster than the speed of light by 20 parts per million. These experiments and tests were done in the physics laboratory in central Italy, under the mountain of Gran Sasso, and conducted about 15,000 times all with the same results. The results were neutrinos arriving 60 billionths of a second earlier with an error margin of plus or minus 10 billionths of a second. They experimented for three years before making public this amazing discovery on September 22, 2011. To have a better understanding, one must first be familiar with some basics of physics. Neutrinos are electrically neutral...

...Economics Development Impacts High Speed Rail Tom Kayo TMLT601, I001, Fall 15 American Public University Emmet Fritch December 26, 2015 Abstract This paper premise is the economic development impacts of transportation in general, as examined by Kumares, Sinha & Labi (2007). Multiple studies have revealed that investments in public transportation ultimately drives productivity and economic growth (Kumares, Sinha & Labi, 2007). This paper however will move away from highways and most common types of transit systems to focus on high speed rail and its potential economic development impacts in the United States. By examining additional resources such as World Bank analysis, papers from the MIT library, and reports from non-profit advocacy groups, this paper seeks answers on why a project with tremendous economic benefits has not yet happened in a country known for always being first when it comes to leading in innovation and economic development. Introduction In Kumares et al.’s. (2007), two types of transportation impact on economic development are listed. One is the impact on the overall economic development, driving income and jobs, for instance, and the other is the positive effect on investment, property appreciation and tax revenue. All of this correlates with higher wages and better communities. At the same times, when looking at other developed and emerging countries, like countries of the European Union and China for example it’s...

...on the California High Speed Rail System (CAHSR) - Is It Feasible? By Hardeep Ramesh, MS ISE Engineering Economics (ISE 460) University of Southern California December 3, 2010 Abstract: California High Speed Rail (CHSR) system is a mega project planned by the California High Speed Rail Authority (CA HSRA), connecting the major metropolitan areas of California. The project finalized in mid 2000, is estimated to be one of the most expensive of its kind. It is in the lines of the high speed rail systems existing in France, Japan and China. The cost of the total project, which will cover around 800 miles, is estimated to be around $45 billion as of 2008. At this time of economic instability and no proper funding expected the big question is that - is the project economically feasible? This case study evaluates the financial benefits of the project. It will show the various sources from which the project will be benefited. Since it is a public investment if the total benefits are more than the total costs it is said to be economically feasible. This case study uses the benefit-cost analysis as an evaluation to establish this. It uses only the benefits and costs which are quantifiable and those which are not duplicative. Introduction: California’s burgeoning population and increasingly congested highways and airports demanded new transportation solutions.
