...Circuit 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...

...and well documented (introducing appropriate comments) 4. Submit your assignment file on Moodle well on time to avoid system congestions or break-downs during the last minute Problem 1: Tourist spots in London As a tourist in London you want to visit 7 spots and minimize the time spent on visiting these 7 spots. The details of the 7 spots including their ID, time to see the attraction, and opening time are given to you (Range A3:D9 in given spreadsheet). Note that you want to visit each spot only once. Range B13:H19 in the given spreadsheet contains the travel time (in minutes) between any two spots, 9999 stands for infinity. For example: travel from 2 to 5 (Trafalgar Square to Tower Bridge) takes 22 minutes. You can assume that all other times (wait times for transport, queues for attractions etc, are already accounted for in the sightseeing time and travel time). The subroutine calc_schedule uses this information to calculate the route to be taken from the starting spot (given in G3) at the starting time given in G4. The subroutine prints out the route below the travel table (skipping one row to maintain readability) and in the next row, the respective times that you will reach each spot. In-case, the heuristic cannot find a solution, an error message is printed on the spreadsheet. The following ranges on the spreadsheet have...

...Intro Speech Evaluation As for my Speech I felt like I did jump right into the topic of what I was about to tell the audience. I could have made my transition a lot better. I felt as if I did have my organization of the speech laid out perfect, but when I actually talked it wasn’t. But everything was in order. For my ending I really just walked off the stage because I forgot everything that I wanted to say. I couldn’t finish all my thoughts. I kept moving around and stayed looking down. I really didn’t make enough eye contact with the audience like I was suppose to. I know for my next speech to get a spot on the floor and just stand in that same spot. Also I am going to pick spots in the audience that I can look at like empty seats, the wall, or even their shoulders so I can look like I am actually looking at them when I talk. My body language portrayed that I was nervous and didn’t know what I was talking about. I felt like everybody could hear my voice but I was still looking nervous. It wasn’t between 2-4 minutes because I had forgot my thoughts. I hated my speech altogether. I couldn’t finish my speech and I was disappointed with myself. I know my audience was looking like what is he talking about from how I kept moving around and looking down at the podium. If I could have did anything different I would have finished my speech all the way. When I prepare for my next speech I am going to come to you way before to get clarity if everything is good and in order...

...Ashley M. Taylor English 102 Professor Catanese “Pining for Parking spots” Its 7:45 Monday morning and you’re on the road to campus and hoping that a parking spot is available. Not only do students face this dilemma, but teachers do as well. Some professors are tardy to classes due to traffic but what about the major traffic that comes with trying to find a parking spot on campus? The morning rush of various professionals during the day is time consuming and everyone seems to have some place to go and they are in a rush to get there. Students who live off-campus have to worry about the possibilities of having to miss a class as a result of no parking on campus. With this ongoing dilemma directly affecting the students and faculty, I propose that USC opens another parking garage on campus to better accommodate these people. If the University of South Carolina were to build at least two new parking garages on campus, I guarantee that the complaints about the lack of parking on campus would decrease, and attendance by students as well as professors would not be directly affected by the strain of parking spots on campus. As a result of construction of the Patterson dormitory, USC housing has the stressful task of trying to find proper housing for the incoming freshman of the fall semester. The dorms normally reserved for upperclassmen such as East, South and West Quad, as well as the horseshoe apartments are now being occupied by freshmen and upperclassmen must scramble...

...and Dan Health’s “Finding the Bright Spot” In the chapter “Find the Bright Spots” taken from the book Switch: How to change thing when change is hard, the authors state that: when changing things, there’re bright spots in your field. You need to direct your followers- the Riders by following these bright spots and make the Elephants’ expect that change is possible and the Path is clear. In 1990, Jerry Sternin came to Vietnam to fight malnutrition with barely support from the government. Firstly, his team found that there were a lot of problems such as poor sanitization, poverty, out of clean water. However, in six months and almost no money, solving these problems became useless. After weighting, Jerry found that there were healthy and well-nourished kids despite their poor families. There were his bright spots. Besides that, he directed the mother’s Riders to shadow the bright spots’ mothers. Uniquely, these kids ate four times instead of twice a day, parents fed kids by hands, or mixing rice with small shrimp, crab and sweet potato green provided vitamin and protein for the kids. Because knowledge couldn’t guide the villagers, Jerry created cooking classes at the bright spots’ houses, provided detailed instructions to the mother’s Riders. Gradually, more mothers followed and this made the mothers’ Elephants believe in making their kids healthier. Six months later, 65 percent of the kids became healthier. Bright spots exist in every field that you deal with...

The most important climatic conditions are the temperature and the light intensity within the greenhouse.This paper describes the implementation and configuration of the wireless sensor network using the Sun SPOT platform.It also uses a Time Series Algorithm to predict the temperature variation. Keywords: WSN,SunSPOT,TimeSeries,Java,Zigbee,Back Propagation 1.Introduction The most important factors for the quality and productivity of plant growth are temperature and light. Continuous monitoring of these environmental variables gives information to the agriculturalist to better understand, how each factor affects growth and how to manage maximal crop productiveness. The optimal greenhouse climate adjustment can enable us to improve productivity and to achieve remarkable energy savings - especially during the winter in northern countries. Increased number of measurement points should not dramatically increase the automation system cost. It should also...

For example, A could be going faster right now but at constant speed (aA = 0), while B is going slower now but has his gas pedal on (aB> 0), so B will overtake A soon. However, we really have no idea what the situation is, so without knowledge of the acceleration along with the velocity, we can’t predict anything. 12. They are certainly not always the same. Check Worksheet #2 for a good example: the girl going around the carousel has zero displacement and thus zero average velocity, but certainly went at a nonzero average speed as she went around the circle. 13. To her, the ball looks like it drops straight down, despite the train’s speed (vBT is the same as a normal falling ball). But to someone standing still on the earth outside, they see the ball moving in a curved parabolic path, as if it’s launched with an initial velocity of vBE = (175 mph, 0), because it’s “boosted” by the train.

...PREFACE: To The Evaluators Of My Training Program If we look at our surroundings, all the human beings would be wearing some cloth, most of which is woven. Today the average consumption of textile products per person per year is 6.7 Kg. The world population has crossed the six billion figure, so more than 40 million tons of fabric is utilized by the mankind of world each year. Indeed both consumption per person and population are increasing at a faster pace. Consumption per person is confidently expected to increase after December 2004, as WTO would eliminate the quota costs, import duties and other such tariffs. To be competitive in the textile market, the manufacturers of this industry will have to transfer this benefit of low cost to the customers, which in turn would encourage the customers to buy more. This process would yield economies of scale for the producers and thus the textile companies will achieve enormous growth. Pakistan has competitive edge over many other countries in the textile industry, so it will more focus and capitalize on this concern. This gives a view of future prospects of opportunities in textile and importance of textile products. More specifically the shade, look, handfeel of fabric and durability of shade are the crucial factors of concern for the textile customers (these factors are expected to gain more attention of customers in future). These factors are complied in dyeing processes. Kohinoor Dyeing Mills Ltd. (KDML) is involved in the...

...Legal Memo To: Attorney John Smith, Esquire From: Paralegal Re: Westen Vs. Jane Date: March 18, 2002 This memorandum follows your recent assignment where in you requested that I contact Mr. Mark Vision, who witnessed our client Mary Jane’s accident, and determine where Mr. Vision was in association with the accident, the approximate speed of the other vehicle, the weather conditions and any other information that would be useful in either shifting liability or alleging contributory negligence on the part of plaintiff/driver. Analysis of the Interview I contacted Mr. Mark Vision on March 4, 2002. He is an African American male, very tall with a slim build. He wore business casual clothes and he seemed a little nervous, but he was very respectful and well mannered. He was very forthcoming with all of the questions he was asked in the interview. He seemed very truthful and reliable and answered every question with a matter-of- fact attitude. He remembered the entire accident very vividly. He would make a favorable witness for our case, because he feels that Ms. Jane is not guilty. Mr. Vision advised me that he was on the way to work at his part-time job Saturday March 18, 2002. The reason he did not give a statement at the time of the accident, was because he is the Manager and had to be at the company early to let the other workers in and didn’t want to keep them waiting. But Mr. Vision did give the Police his contact information. It was raining that...
