systems in Beijing. Wang et al. (2008) established a model based on VSP and speed, which provided insight that how different levels of cruise speed and acceleration affect vehicle fuel consumption. The model prediction shows that vehicle fuel consumption per unit distance is optimum at speeds between 50 and 70 km/h which is similar to the observed data from PEMS. This is evident in the literature that in order to improve both the applicability and accuracy of the existing emission models instantaneous vehicle

While each vehicle reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly at speeds above 50 mph. You can assume that each 5 mph you drive over 50 mph is like paying an additional $0.24 per gallon for gas. Sensible driving is also safer for you and others, so you may save more than gas money. $150 is the average speeding ticket in the U.S. And if speeding 80 or higher the fine can be even more, and may have had to appear before a judge

Derek Castle I jumped the railroad tracks on Jefferson Street and exceeded the speed limit. I know that I made a mistake, a big mistake that could have hurt me and others, but thankfully that wasn’t the case. I know what I did was dumb and irresponsible and it will not happen again. You need to always wear a seatbelt. You should take your time while crossing railroads, you should only go the speed limit if not slower, when coming to a stop sign, make a complete stop and look all around you

There are speed limits for a reason. It is to keep people safe so that everyone can travel the roads safely. Without speed limits there would be chaos everywhere. There would be more wrecks and more fatalities with speed limits not enforced. The roads wouldn't be safe to drive for anyone especially the elderly and new drivers. Currently speed zones are posted in almost every area we drive from school zones to interstates. School zone speed limits are posted slower so that students can cross

Introduction: Every year approximately 1.25 million people die due to car collisions worldwide (WHO, 2015). Of these deaths, speeding is the greatest contributing factor in Australia (Transport for NSW, 2015). A greater speed increases both the chances of a crash occurring and the severity of the crash. Intelligent speed adaption (ISA) is a newly designed technology that affects many social and environmental areas. This leads to question whether ISA should be compulsory in all new cars. How it

Do you know what to do if you come across a railroad when driving? Let's talk about the safety precautions you need to take when approaching a railroad. A few of theses many precautions are always slow down when you come to a railroad crossing, never pass a car that is going your direction at a railroad crossing, do not park closer than 50 feet from a railroad crossing unless signs indicate that you may or it is allowed by local law, when you stop at a crossing, you must be between 15 and 50 feet

A high-speed collision with any vehicle can be devastating. However, a high-speed collision of a car with a semi truck often has a grim outcome for the motorist. The rear underride guards of semi trailers don't offer much in the way of a crumple zone for absorbing impact energy. Damaged or rusted guards offer virtually no protection at all. In addition, hitting one at an offset (with the front left or right side of your car) causes severe damage to the car and may demolish the area occupied by the

Reeves claims that speed safety cameras are effective and “violations have dropped an average of 63 percent where speed safety cameras already exist.” The cameras are carefully calibrated and are not activated unless a vehicle is traveling more than 10 miles above the speed limit which eliminates the possibility of malfunctioning. Reeves believes that “adding more speed safety cameras in school zones would calm traffic citywide [and] train drivers to obey the law.” While motor vehicle crashes are the leading

Introduction to character- First line- Has anyone told you the story about how someone named Ryan Williams moved the nitro circus stands? Problem- Ryan Williams was riding his scooter at nitro circus. The ramp was almost straight down during this time. So he had to start very slow otherwise he drop straight down. The moved slowly but when he got level with the ramp his foot slipped and pushed him faster. The moment that his scooter started to roll down the ramp he started going about 2,000 mph

Speed limitation is one of the most argued topics. Some say that it is not a big deal as others make it. However they are wrong, speed limitation is very important and will always be. Without speed limitation there would be more accidents as well as deaths. Yes, it seems harsh but that is the truth. We intend to always give facts. Speeding is one of the most common reasons for death. Even though there are accidents on a daily, imagine if there was no speed limitations. Speed limitation is so
