Driving Directions to Sea-Tac Airport

Increased speed makes the laws of physics become more and more important to the driver. These laws, although not enforced by a policeman or written by a law producing body, are absolutely binding on all drivers, and no one can relax their effect. The laws of physics control any and every object that moves. The particular laws which apply to driving cover areas such as friction, centrifugal force and inertia, impact, and gravity. You should always remember that these laws apply to city driving as well as to driving on the highway, because their significance increases proportionately with the speed at which you are travelling. However, this article on highway driving would seem the best place to discuss their importance.

Proper sight requires sufficient light and time for a picture to impose itself on the retina of the eye, be relayed to the brain, and thereby trigger a reaction by the driver. This means that traffic signs, signals, and pavement markings become increasingly important when driving at higher speeds. These give the driver advance warning of any curves, hills, intersections, or railway crossings that may be ahead, as well as intended maneuvers by other drivers. A driver must learn to recognize all signs and signals instantly, for at higher speeds the time for recognition and reaction becomes shorter and shorter. To facilitate recognition, signs and signals throughout the United States are standardized by shape and color and can reflect light to be seen at night. Remember, it takes time to observe a sign, signal, or condition, and then react to it. Reaction time for a given driver is fairly constant, but the distance travelled in this time is directly related to speed. Therefore, stopping distances and distances required for evasive action become greater as speed is increased.

Friction

Friction is the force which opposes the motion of one surface over another, and is the means through which a vehicle may move in a straight line, or may turn or stop. This force is exerted entirely through four small friction areas, also known as, tires. If we assume that the average reaction time is 0.75 seconds than common sense tells us that the faster the car is travelling, the greater the distance it will take to stop. The difference in stopping distance from 40 miles per hour to 70 miles per hour is approximately 3.5 times greater. This means that if you can stop within 100 feet at 40 miles per hour, you will need 350 feet of leeway to stop travelling at 70 miles per hour.

These conditions only occur part of the time, however: should the force of friction be reduced by ice, snow, rain, oil, mud, loose gravel, a rough surface, or poor tires, then stopping distances will increase drastically and evasive maneuvers will become much more difficult, or even impossible. Because stopping distance increases more rapidly than speed, it is important to allow a greater distance between your car and the car in front as your speed increases.

Inertia and Centrifugal Force

If at any time the frictional force, or traction, between the four small areas of the tire and road surface are lost, control is lost as well, and one or both of the following physical forces may determine the situation: inertia, the tendency of a moving body to keep moving in a straight line unless an outside force acts to change its direction of motion; and centrifugal force, the tendency of a moving body turning about a center to fly away from that center. Centrifugal force can be demonstrated by placing a weight on the end of a string and swinging it in a circular motion. If the string is release or breaks, the weight will leave the circular path and continue in a straight line.

Obviously, a similar effect can happen to a turning vehicle. A car driving around a curve must overcome the centrifugal force in order to make the turn. If the centrifugal force is greater than the friction between the tires and the road, the car will not be able to turn, but will skid off the highway. The key point is that the friction increases with speed, but the centrifugal force increases even more rapidly. Therefore, the faster your speed, or the sharper the turn, the greater is the chance that you will be unable to get around safely. If you remember this principle, you will realize that you must slow down before entering a curve, especially if the road is slightly slippery

Brakes should never be applied after entering a curve, as this has a tendency to reduce the friction between the wheels and the road. Remember, friction enables you to move your car, control it, and stop it. When you consider that for each tire the area touching the road surface is about equal to the size of your hand, it is understandable that many factors can cause loss of friction, and resultant loss of control. The greater the speed, the greater the possibility this may happen - and the greater the consequences. Speed must always be adjusted to suit road conditions.

As well as the speed of the car, another factor determining whether or not you will be able to make a turn safely is the angle at which the road is banked through the curve. The easiest is a banked turn (similar to a race track); the second, a flat road surface; and the third, a crowned surface. The flat road surface is dangerous at high speed, and in comparison, in a turn, the crowned surface can only be negotiated at low speeds because the car is tilted against the direction of the curve. On entering sharp curves, there is usually an advisory speed sign posted, telling you the speed at which the curve may be safely taken. One who ignores these signs is indeed a very foolish driver.

Kinetic Energy and the Force of Impact

If control of a car is lost, the usual result is collision, either with another car or with a fixed object. The all important variable in this situation is the force of impact. The force of impact itself is a function of the speed and the weight of the car. If you double the speed of a car before a collision, the force of impact is four times as great. If you triple the speed of the car before collision, the force of impact is multiplied nine times! Weight also has a part to play here; if the weight of the vehicle doubles, the force of impact doubles too. The total result of doubling the speed and the weight of the vehicle would be to increase the force of impact eight times. Therefore, any collision would necessarily be eight times as damaging. In effect, the impact of hitting a solid object at 30 miles per hour is like driving off a three story building.

Highway engineers use several techniques to reduce the force of impact in cases of unavoidable contact with surrounding objects. Smooth metal guard rails allow a car to glance off rather than hit solidly. Wide road shoulders, free of obstacles such as trees, culverts, and bridge abutments, help to reduce the hazard. Where light and sign standards are essential, these poles are designed to sheer or break off easily on contact. The best way to make sure that the force of impact does not act upon your car is to drive at all times in a manner which will avoid collision with any and all objects!

The Force of Gravity

Gravity - the force which attracts objects downwards towards the center of the earth - will cause cars to lose speed going up hills, thereby decreasing their stopping distances; and to accelerate going down hills, thereby increasing their stopping distances.

A good driver will cut his speed when descending a hill; on steep grades, he should put his gear selector into low, so that the engine of the car will act as a brake. Hills are potential driving hazards for other reasons also. They limit visibility; the driver should not pass on or approaching a hill, no matter how slowly the vehicles in front are moving, unless there is a passing lane. At the crest of a hill, the driver must be alert for approaching cars not in their proper lane, or for obstacles in the road ahead, such as a car stopped while waiting to make a left turn. Remember that you must be able to stop your vehicle in the distance you can see ahead either day or night.

Simple Guide on Selecting GPS Navigation System for Your Car

Parking lots are convenient, but they are also dangerous -- accidents waiting to happen. Grocery store lots are especially dangerous when people are getting off work and rushing to buy food for dinner.
Unpredictable drivers also contribute to parking lot accidents and you have seen them all.

Cross country drivers -- the ones who drive diagonally across the rows -- are one danger. They often drive across several rows before coming to a stop. Some are so intent on getting the space they want they reverse directions. You can hardly tell where they are headed next.

The "ignore the lines" drivers are not much better. These drivers park across the white lines and take up two, sometimes three, parking spaces. Park next to these drivers and you take a chance that your car will be dinged.

Then there are the "ignore the rules" folks. Though they are not handicapped these drivers make a bee-line for handicapped spaces. What's more, they are not the least bit embarrassed about it. Ignore the rules drivers think they are entitled to these spaces.

"Not looking behind" drivers are really dangerous. They are in such a hurry they forget to look behind them before backing out. Collisions and near-misses are part of their day. Unfortunately, they endanger careful drivers like you and me.

I was only in the grocery store for 20 minutes. In that time a driver hit my car door. The dent was small, and it was also costly, $500 to be exact. When I reported the accident to my insurance company the agent said, "We hear this story all the time." How can you steer clear of parking lot accidents?

1. Use your defensive driving skills. Drive as if everyone else is crazy.

2. Turn on your car lights for safety.

3. Circle the lot first and and look for empty spaces.

4. Drive slowly.

5. Watch for rolling carts, running kids, and parents with strollers.

6. Obey all stop, one way, and yield signs.

7. Park at the rear of the lot where there are usually fewer cars.

8. Choose a spot that is far from tent sales, garden sales, and high school car washes.

9. Park beneath a light.

10. Center your car between the white lines.

11. Before you back out look behind you and in both directions.

12. Go forward to the next row so you do not have to back out.

Share these tips with teenage drivers. The tips do not guarantee that you and your teens will be accident-free, but they stack the odds in your favor.

Online Driving Maps - What Are the Most Popular Ones?

There are many fast and easy ways to get driving directions. If you are a person who plans your travel before leaving home, you probably make sure that you have proper directions before leaving your home. However, some people find that they need to get to a location with no idea of how to get to the location.

When you are going to a meeting, the stress of being lost can make getting to the location even harder. There are a few simple steps you can take to make sure you get to every location on time and with a minimum of false starts. When you are scheduling an appointment by telephone, it is always a good idea to get the major cross street for the location.

Knowing the major cross streets will greatly reduce the amount of driving you must do to try to find an address. This will also save time if you are traveling to an area for the first time. There are many resources available to assure that people do not get lost. Having a device in your vehicle that allows you to program in addresses and leads you to the location with verbal commands is convenient.

These devices are available in different price ranges and have different features and functions, depending on the type of device that you select. Some vehicles come with on-board directional devices. These systems are connected to the same satellite that reports your location via GPS if you are in an accident.

The main difference between the built-in devices and those that are purchased from electronics sources is that they tell you the names of the streets that you should turn on, or are passing as you are moving toward your target location. Another feature of some systems is the ability to get assistance if you are lost.

These systems give you the ability to get more specific directions if you are lost. You can also make several choices based on how you want to get to your location. You may choose the shortest route, avoid highways, make stops at other locations on your way to the location, or much more.

When you are choosing a device for your vehicle, it will be important that you are able to get regular updates easily. Roads and routes can change and being able to update your device using your computer will keep your device current. The device you select should also have an emergency beacon so that if you are lost in an isolated area, you can send out a locator signal and get help. This feature has proven invaluable for people who have been on vacation in isolated areas or areas where they were stranded due to weather or a breakdown.

The best driving directions devices will have a 24-hour customer service line where you can get information if you have questions or issues with your device. The representatives will be able to provide technical advice if you have difficult setting up your system or using it when you are out of your normal traveling area.

Career Icebreaker: Finding Your Hidden Talents and Resources

Whether you are searching for directions to the next town or across country, you can go online to download free driving directions. You can search by quickest route or shortest mileage, depending on which is most important to you. These maps will also tell how many miles you will travel and approximately how long it will take you to get there.

Such sites as Expedia.com and Mapquest will allow you to find directions to just about any destination. When you go on the sites, you might have to maneuver a bit to get to the driving directions. For instance, on Expedia.com you have to click on maps and then click on get driving directions.

You will be prompted to put in your departure address and arrival address. We have found that all the sites that provide free directions work well for the most part. However, if your departure or arrival address is in a very rural area, new neighborhood or small town, you might not get the correct driving directions. Your directions will probably end by saying something like "take local roads". If you get that response, you are better off contacting a business in the area to get them to give you directions.

In addition to driving directions, you can download free maps of different cities. You will find this to be true more for larger cities than small towns or rural communities. Free State maps arm you with Interstate and Highway information.

If you are traveling a long distance, you should consider downloading a map of the area in case you run into road construction and detours. For long distance travel, purchasing a map or atlas, such as a Rand McNally map is probably in your best interest. It is always a good idea to keep an atlas in your car of the state in which you live and other states that you frequent just in case you get lost or want to take an alternate, more scenic route.

For free driving directions, the internet is your best place to start. Most of the directions are easy to read, even for the most map challenged people. If you have any questions about the maps you download, it is best to check with someone in your destination city to be sure you know where you are going. These directions also provide you with helpful information about how many miles you will be traveling and approximately how long it will take you to arrive at your destination. This information allows you to plan for the appropriate amount of travel time and to decide where you might want to stop on your way to your destination to spend the night or just stretch your legs.
