Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Exit Number shopping experience:

1. Compare - without doubt the biggest advantage that the Exit Number offers shoppers today is the ability to compare thousands of Exit Number at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.

2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about

3. Testimonials - don't know anybody that has bought a Exit Number? Wrong! If the Exit Number is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.

4. Questions - Got a question about Exit Number then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....

5. Reputation - Never heard of the company selling Exit Number? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Exit Number and build up a picture of their reputation for sales, returns, customer service, delivery etc.

6. Returns - still worried that even after all of the above your Exit Number wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.

7. Feedback - happy with your Exit Number then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.

8. Security - check for the yellow padlock on the Exit Number site before you buy, and the s after http:/ /i.e. https:// = a secure site

9. Contact - got a question about Exit Number, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.

10. Payment - ready to pay for your Exit Number, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.

in Volusia County, Florida. In this case, mile-based exits 111A and 111B had been sequential exits 53CA and 53CB, as the 'OLD 53CA' tab shows. sign) matches a nearby mile or kilometer marker.An exit number is a number assigned to a road junction, usually an exit from a freeway. It is usually marked on the same sign as the destinations of the exit, as well as a sign in the gore (road).

Exit numbers typically reset at political borders such as U.S. state lines. In some areas, such as New Jersey (and its New Jersey Turnpike), the numbers are a part of popular culture; a clichéd greeting is "what exit?"

Some non-freeways use exit numbers. Typically these are rural roads built to expressway standards, and either only the actual exits are numbered, or the at-grade intersections are also numbered. An extreme case of this is in New York City, where the Grand Boulevard and Concourse and Linden Boulevard were given sequential numbers, one per intersection. A milder version of this has been recently used on the West Side Highway, also in New York, where only the major intersections are numbered (possibly to match the planned exits on the cancelled Westway (New York) freeway). Another case is the Nanaimo Parkway in Nanaimo, British Columbia carrying British Columbia Highway 19, where all exits are numbered though all except one are at-grade intersections. Some other intersections on Highway 19 outside Nanaimo are also given numbers.

As a means of educating motorists, some state highway maps include a brief explanation of the exit numbering system on an inset. Iowa Department of Transportation maps from the 1980s and 1990s included a picture or drawing of a milepost and briefly described how Iowa had included milepost references near interchanges on the map.

Sequential numbers , with its unusual exit signage, displaying exit 8. This interchange was opened in 1951.The first exit numbers were sequential. This type of exit numbers usually begins with exit 1 at the beginning of the road; each subsequent exit is given the next number. The first implementations gave each ramp its own number, even when two ramps existed for two directions of a road; later implementations used directional suffixes, as in 15N/15S or 15E/15W, and current United States and Canada practice is to use 15A/15B. In France and Japan, decimals are used, as in 15.1 and 15.2.

Toll roads, especially those using tickets, lend themselves nicely to sequential numbering, as each toll plaza gets its own number. Problems arise when exits are added. For instance, an exit between 15 and 16 would typically be 15A. On the New York State Thruway, an exit was added between 21 and 21A, leading to the sequence 21 - 21B - 21A - 22. In Florida, some new exits got the suffix C, so that if it had or acquired separate exits for the two directions, they would be 15CA and 15CB rather than 15AA and 15AB. There are also occurrences of this happening on the New Jersey Turnpike as well, with the original interchanges opening in 1951, with some new ones opening in the 1970s and 1982.

Occasionally sequential exits are renumbered due to added exits. For instance, the Hutchinson River Parkway in New York was renumbered so that its northernmost exit, 27, became 30. However, the Merritt Parkway, which continued its exit numbers in Connecticut, was not renumbered, and the sequence now jumps from 30 down to 27 (the interchange on the state line had two exit 27s, and now has exits 30 and 27).

The Atlantic City-Brigantine Connector in Atlantic City, New Jersey uses letters without numbers for its exits; it has many exits in a short distance, and the South Jersey Transportation Authority may have wanted to avoid sequential numbers.

==Distance-based numbers== in Quebec in QuebecAs more highways were built, the limitations of sequential numbering became clear, and states began to experiment with distance-based (mile-based) exit numbers. The first mile-based system known was implemented on the Garden State Parkway in New Jersey in the late 1950s. Michigan also implemented mile-based junction numbers on Interstate 94 in the 1960s. In this system, the number of miles from the beginning of the highway to the exit is used for the exit number. If two exits would end up with the same number, the numbers are sometimes modified slightly; this is often impossible and exits are given sequential or directional suffixes, just as with sequential numbers.

An exit can be numbered by where the exit in the direction of increased mileage leaves the freeway, or by where the road that the exit serves crosses the freeway (which is occasionally ambiguous). From this number, the integer exit number can be determined by rounding up, rounding down, or rounding to the nearest integer. Many jurisdictions prefer to avoid an exit 0. To this end, the numbers are either rounded up to get the exit number, or any exit that would get the number 0 is instead numbered 1. Examples of highways with an exit 0 are British Columbia Highway 1 on the mainland, Interstate 70 in Wheeling, West Virginia along the West Virginia-Ohio border, and Interstate 65 in two locations: at its terminus with Interstate 10 in Mobile, Alabama, and just north of the Ohio River in Jeffersonville, Indiana.

In areas that use the metric system, distance-based numbers are by kilometer rather than mile. A few highways, such as Delaware Route 1 and Interstate 19, have been renumbered from miles to kilometers, even in areas that typically use miles.

Distance-based numbers have several advantages. They match the mileposts along the road; it is thus easy to calculate how far one has to go. Additionally, most new exits don't need letter suffixes, as in a sequential system.

On the other hand, there are some disadvantages to changing from a sequential system. Businesses and motorists have to adapt to the changes, and it costs money to replace the signs (as well as for temporary "old exit" tabs to ease the transition). Additionally, some argue that it is pointless to change to mile-based numbers, as the numbers would have to be replaced again if the United States switches to the metric system. Ontario's Highway 401 (Ontario) changed to a mile-based system from a sequential system of exit numbers, then had to switch again to a kilometre-based system when Canada metrification in 1977.

Exit numbers by country United States Canada Of all the provinces in Canada, only two use sequential numbers: Nova Scotia and Newfoundland and Labrador. The territories of Yukon Territory, Nunavut, and Northwest Territories use no exit numbers, as there are no freeways or expressways in the territories. Prince Edward Island has no exit numbers either, since it only has a few short freeway segments. Nova Scotia also numbers level junctions on designated express highways.

New Brunswick, Quebec, Ontario, Alberta and British Columbia used kilometre-based exit numbers on most expressways in those provinces.

• Saskatchewan does not really use exit numbers, but on a section of Saskatchewan Highway 11 from Regina, Saskatchewan to Lumsden, Saskatchewan, letters "A", "B", and "C" are used as "exit letters".

• Ontario has the oldest exit number system, having started posting exit numbers sequentially in the 1960s along Highway 401 (Ontario). Most short freeways do not have exit numbers, and until about 2000 (with Highways Highway 11 (Ontario) and Highway 69 (Ontario)/Highway 400 (Ontario)), incomplete freeways also did not have exit numbers.

• Quebec has the second oldest system, and the only junction numbering system to use mile-based junction numbering before the Canadian metric conversion in the mid-1970s.

• Manitoba has the fewest posted exit numbers. The province started posting exit numbers on the Perimeter Highway in 2001.

• Alberta has the newest exit number system. The province started posting exit numbers on Alberta Highway 2 in 2004, and has since extended the system to Alberta Highway 1.

Taiwan Taiwan uses distance-based exit numbers in kilometers. If two exits are located within the same kilometer mark, the Roman letters are appended to differentiate the exits. Taiwan did experiment with sequential exit numbers with National Freeway No. 1 for a couple of years, but abandoned the experiment in 2004.

Prior to 2006, Taiwan exit signs were generally near replicas of their US counterparts. However, the exit signs now not only indicate the distance number, but they also display the Chinese code-name for the interchange.

Hong Kong Exit numbers were introduced to major Hong Kong routes in 2004, in conjunction with the re-organization of the route numbers. A sequential numbering scheme is used.

New Zealand New Zealand began introducing exit numbers in 2005. It uses a distance-based numbering system. The distance to the exit is measured from the origin of the highway. That is:

• State Highway 1 (Northern motorway) measured from the origin of SH1 at Cape Reinga
• State Highway 16 (Northwestern Motorway) measured from the origin at the Port
• State Highway 20 (Southwestern Motorway) measured from the origin at SH1

There is no exit zero. If there is an exit within 1.499 km of the origin, Exit 1 is used. Exit 2 would be between 1.500 and 2.499 km of the origin. Subsequent 'exit zones' are at 1km intervals.

Letter suffixes are added at multi-exit interchanges, or where two or more exits exist within the same exit zone. For example, State Highway 1 (Southern Motorway) has an Exit 429A (Symonds St), Exit 429B (Wellesley St) and Exit 429C (Port).

Instead of replacing existing ramp and link signs, the exit numbers were added as supplementary information. Thus drivers can navigate either by exit number or name.

Exit numbers are only used for exits that may be used by all vehicle types. Bus- or emergency vehicle-only exits would not be numbered.

The Philippines Metric distance based numbers are used on the tollways radiating from Manila. Supplemental "A" and "B" designations are appended to signage at the ends of slip roads. Freeway signage, exit tabs, and kilometer-posts are nearly identical in appearance to American freeway signage.

Japan The main expressway system uses sequential numbering; Metropolitan Expressway systems also use sequential junction numbeing, usually appended with the expressway number expressed thusly: 5-1; 5-2, etc. There are multiple toll expressways not operated by the major national syndicates or the Metropolitan Expressway Authorities that have no junction numbering scheme.

Australia Uses distance based numbering on a section of the M1 (Pacific Motorway) south of Brisbane.

South Africa Uses distance based numbering (in kilometers) on main motorways. Exit numbers are reset on the borders of the provinces as they were until 1994. This means that exit numbering may change completely in the middle of a province.

Great Britain and Continental Europe Most European countries use sequential numbering schemes. Spain uses distance based numbering on its Autovias, but not on its Autopistas. Austria and the Czech Republic use distance-based schemes. A number of European countries (including the Netherlands, Belgium and France) do not number motorway intersections, apparently because one cannot "exit" the motorway there. Countries like Germany and Switzerland have attributed numbers to their exit, but instead of the usual exit symbol, they are given a specific interchange symbol.

Italy only uses (sequential) numbering on the ring roads of a couple of cities, including the ring road of Rome (GRA) and Milan (Tangenziali). At one time, it referred to junctions on the Autostrada Del Sole by number, and published same on toll tickets; though these may not have been posted on signs.
