Traffic Modeling Essay Example

Traffic Modeling Essay Example Traffic Modeling Essay Traffic Modeling Essay Traffic Modeling Traffic modeling in a sense is an overview of general traffic flow calculations. It provides a blueprint and a layout of incoming and outgoing traffic with a formula to calculate the timing of overall cars involved within the traffic flow. With the vast roads and streets managing traffic can be difficult without the proper calculations. Mathematical functions can be ways to express simplicity with the eliminations of difficult equations through the use of practical formulas. Many can be used to resolve the model of how traffic flows, but Learning Team D has used the Gauss-Jordan Elimination technique to simplify and conclude the precise amount of car flow managed per street and per hour. Noticing that Elm Street and Maple Street can only handle 1500 cars per hour, and the other streets with the maximum of 1000 cars per hour handling capabilities, Gauss-Jordan Elimination came into effect. An augmented matrix took form to assist with the elimination and help create numeral systems of linear equations. These linear equations explain how the Gauss-Jordan Elimination technique is performed. With minimal information given from this equation this technique helped shaped an understanding of where numbers can be properly placed. There are seven total variables and six intersections in the equation with each variable representing the number one. Using the Gauss-Jordan Elimination technique, ones and zeros have to be placed in a precise order to result in perfect flow and manage accountability of vehicles coming in and out of the road. Solving the linear equations gave the total number of vehicles within the hour passing through each road which is represented by the variables. The result is as follows with the sum of the combined roads equaling out to the total vehicles per hour: Intersection 1 (f+a=1700), Intersection 2 (g+b=1600), Intersection 3 (c+b=1500), Intersection 4 (c+d=1600), Intersection 5 (d+g=1700), and Intersection 6 (e+f=1800). With these linear equations formulating the result and managing the constant flow of traffic was simple with the help of the Gauss-Jordan Elimination. One-way streets generally have higher motor vehicle capacity than two-way streets. Increasing a streets capacity induces more driving. One-way streets generally serve through-traffic first, local traffic second. One-way streets are oriented towards serving people driving through the neighborhood rather than people who live, work, shop, walk and bike in the neighborhood. While one-way streets can simplify crossing for pedestrians who only need to look in one direction, and some studies have shown that one-way streets tend to have fewer pedestrian crashes, one-way streets generally have faster vehicular speeds than two-way streets, making crashes deadlier and more destructive. Making a one-way street back to two-way would allow better local access to businesses and homes and to slow traffic. Two-way streets tend to be slower due to friction, especially on residential streets without a marked center line, and they may also eliminate the potential for multiple-threat crashes that exists on multi-lane, one-way streets Single or double traffic lanes, either face-to-face or with a median, sometimes flanked by parking. The benefits might be less driving, less confusion, and better traffic access. More might also be eliminates the need to drive blocks and blocks out of the way. You might not have a need to make extra turns to get to nearby destinations. In conclusion traffic modeling helps with maintain the roads and the traffic in a constant flow. It can tell you what the maximum amount of cars a street can handle without slowing down or restricting the access of the street. Solving these equations can accurately predict the impact that more traffic can cause on a street. These equations can be applied to any traffic flow model and give you an answer that you can work with.

Over a Dozen Cool Science Dating Ideas

Over a Dozen Cool Science Dating Ideas So, you used your favorite chemistry pick-up line and secured a date who appreciates your love of science. Heres a look at some types of dates that might be perfect if your sweetie is a scientist or is interested in science. Dinner and movie are still a good plan, especially with the right movie, but here are some additional dating ideas. Science Date Ideas Play a sport that involves science. Okay, so there is science in all sports, but bowling, billiards, and darts allow you to gauge momentum and consider trajectories and all that fun math stuff. Ice skating involves friction and angular momentum and possibly some experience with the effects of gravity. Skiing and sledding are also good choices, plus afterward, you get to snuggle up together to get warm again. Play a science board game together. My personal favorites are Nuclear War and its add-on, Nuclear Annihilation. Risk and chess are other great choices.Visit a museum, zoo, or planetarium, or catch a laser light show. Experiment with cryogenic materials together. Dipping flowers in liquid nitrogen are romantic, right? Pretty much anything involving liquid nitrogen or dry ice is fair game. If that sounds dangerous, you could always enjoy Dippin Dots (dry ice temperature) ice cream together. Play with fire. You knew this would be on my list somewhere, right? Light off fireworks tog ether or make your own. Make smores, but see if either or both of you can start the fire from scratch. Learn molecular gastronomy together. Grab a kit online or from a bookstore or follow along with videos online to prepare a meal that applies chemistry to make unusual food. You could also make interesting cocktails using the techniques. Play with a black light together. Check items around the house to see which ones glow when exposed to UV light. Explore science projects you can do using a black light. Grab a telescope and go stargazing. No telescope? Try binoculars or a camera with a zoom lens. If you do have a telescope, its pretty easy to grab photos of your observations using a cell phone, so you can remember the date. Grow magic rocks. You can gaze into each others eyes when youre not watching the pebbles grow into crystalline towers. Get a kit or make magic rocks from scratch. Break out the molecular model kit and make structures. If you dont have a kit, try using pretzels and gummy candies. Watch a movie. Surely you have a favorite science or science fiction movie! Bonus poin ts if its Star Wars and you dress like a character or bring a light saber. Break out the Lego set. Build together. Perform science experiments on real flowers. Flowers are romantic, right? Make a rainbow rose, a glow-in-the-dark flower, or simply color flowers using food coloring. You can perform paper chromatography on flowers to examine their pigments. Download and watch the very first episode of Doctor Who. Break out the paper and scissors. Cut out paper snowflakes. Make a Mobius strip. Make cute little hearts. Grow crystals. There are many household chemicals you can use to grow crystals. Rock candy or sugar crystals are the only ones youll want to taste-test. Order a pizza and play video games. Note to guys: this is only a good date if you pick a game she also enjoys playing (not just watching). Valentines Day  chemistry projects to try.
