Online services for calculating kilometric road distances with free road maps, motorway routes and GPS satellite navigation.
Traffic information and road maps
There are many traffic information services available to motorists able to notify in real time the amount of vehicles on the roads and highways with indications on the possible degree of congestion in the presence of queues, providing an idea of the time needed to reach a determined destination with reduced travel speed in a certain stretch or by suggesting alternative routes to avoid the queues.
As an alternative to the proposed connections, in addition to traditional geographic and road maps in paper form, we can resort to the now widespread satellite navigators.
These handy electronic instruments are used to indicate your position with a margin of error reduced to a few meters and to indicate, after setting the destination to be reached, the best road and motorway route according to the parameters set and any alternative route.
GPS, an abbreviated form of the terms 'Global Position System', is a positioning system based on an American satellite system. The GPS system is made up of a series of 24 satellites in orbit located at a distance of about 20,000 kilometers, which take 12 hours to travel an entire tour around the earth.
These satellites transmit data relating to their position, their identification and the orbit of each of them with hourly data at regular intervals.
The receiving device inside the portable navigators receives these data, processing them to serve the user the answer based on the parameters set, indicating with extreme precision the distance of the receiver from each satellite.
This distance is obtained starting from the comparison of the time transmitted by the satellite with the local one, from which the time taken by the signal to reach the receiver is obtained; this value is then multiplied by the speed of light with the result of obtaining the exact distance between the two devices.
Each satellite navigator, equipped with stored road maps that can be expanded and updated, assists the driver with graphic and vocal indications.
The GPS technology is used, as well as in the road sector, also for trekking excursions in the mountains and for boating with satellite navigators specifically designed for these uses.
