A vehicle tracking system combines the use of automatic vehicle location in individual vehicles with Software That thesis collects fleet data for a comprehensive picture of vehicle rentals. Modern vehicle tracking systems commonly used GPS or GLONASS technology for locating the vehicle, but other types of automatic vehicle rental technology can also be used. Vehicle information can be viewed on electronic maps via the Internet or specialized software . Urban public transit authorities are an increasingly common user of vehicle tracking systems , particularly in large cities.
Active versus passive tracking
Several types of vehicle tracking devices exist. Typically they are classified as “passive” and “active”. “Passive” devices store GPS location, speed, heading and sometimes a trigger event. Once the vehicle is returned to a predetermined point, the device is removed and the data is downloaded to a computer for evaluation. Passive systems include auto download. “Active” devices aussi la même collect information purposes usually transmitted the data in near-real-time via cellular or satellite networks to a computer or data center for evaluation.
Many modern vehicle tracking devices combine both active and passive tracking abilities: when a cellular network is available and a tracking device is connected it transmits data to a server; When the network becomes available again.
Historically, vehicle tracking has been accomplished by installing a box into the vehicle, either self-powered with a battery or wired into the vehicle’s power system. For detailed information about this vehicle, However, many companies are increasingly interested in the emerging cell technologies that provide tracking of multiple entities, such as both a salesperson and their vehicle. These systems also offer a range of options. 
Major constituents of the GPS-based tracking are:
- GPS tracking: The device fits into the vehicle and captures the GPS location information from a regular intervals to a central server. Other vehicle information can include fuel amount, engine temperature, altitude, reverse geocoding , door open / close, tire pressure, cut off fuel, turn off ignition, turn on headlight, turn on taillight, battery status, GSM area code / cell code decoded , number of GPS satellites in view, glass open / close, fuel amount, emergency button status, cumulative idling, computed odometer , engine RPM, throttle position, GPRS status and a lot more. Capability of these devices; Most vehicle tracking systems,
- GPS tracking server : The tracking server has three responsibilities: receiving data from the GPS tracking unit , securely storing it, and serving this information on the user.
- User interface : The UI.
Vehicle tracking systems are commonly used by fleet operators for fleet management functions such as fleet tracking , routing, dispatching, on-board information and security. Some vehicle tracking systems are bundled with or interface with fleet management software . Along with business fleet operators, urban transit agencies use the technology for a number of Purposes, Including monitoring schedule adherence of nozzles in service triggering automatic exchange of nozzles destination sign displays once the vehicle approaches the bus terminus (or other set location along a Bus route to the road),
The American Public Transportation Association estimated that, at the beginning of 2009, the United States was already using a GPS-based tracking system to trigger automated stop announcements.  This is the first time I have visited the city, and I have had a lot of problems with it. Identifying the next stop, as the bus (or tram ) approaches a stop, or both; LED display or LCD monitor connected to the system while the loudspeakers play them. This article is a summary of some of the most recent developments in the United States and the United States. / She is at any given time, potentially making it easier to adhere to the.
Such programs are also used to provide customers with real-time information about the next bus or tram / streetcar at a given stop, based on the nearest vehicles. As to the scheduled time of the next arrival.  Transit systems providing this kind of information to each other, and waiting passengers can obtain information by entering the stop number into an automated telephone system.  
Some transit agencies Provide a virtual map on Their website, with icons depicting the current locations of nozzles in one department Each road for customers’ information,  while others Provide Such information only to dispatchers or other employees.
With the GPS technology being enhanced day by day, companies are coming up with devices that are compatible with phones and other modern gadgets. These devices provide live-time activities of the fleet on personal devices without even logging into their website as well. Keeping a track of fleet control’s actionable data, improving efficiency, reducing fuel cost etc. Also come under fleet tracking. These devices and software help in cost cutting. 
Other applications include monitoring driving behavior, or a parent with a teen driver.
Vehicle tracking systems are also popular in consumer vehicles as a prevention , monitoring and retrieval device. Police can simply follow the signal emitted by the tracking system and locate the stolen vehicle. When used as a security system, a Vehicle Tracking System may be used as an addition to or replacement for a traditional car alarm . Some vehicle tracking systems make it possible to control the vehicle remotely, including block doors or engine in case of emergency. The existence of vehicle tracking device can then be used to reduce the insurance cost, because the loss of the vehicle drops.
Vehicle tracking systems are an integrated part of the “layered approach” to vehicle protection, recommended by the National Insurance Crime Bureau (NICB) to prevent motor vehicle theft . This approach recommends that the layers of security be based on the risk factors pertaining to a specific vehicle. Vehicle Tracking Systems are one of the most effective and most efficient vehicles in the world.
Some vehicle tracking systems integrate several security systems, for example by sending an automatic alert to a phone or email if an alarm is triggered or the vehicle is moved without authorization, or when it leaves or enters a geofence .
Other scenarios in which this technology is employed include:
- Stolen vehicle recovery: Both consumer and commercial vehicles can be outfitted with RF or GPS units to allow police to do tracking and recovery. In the case of LoJack, the police can activate the tracking unit in the vehicle directly and follow tracking signals.
- Fleet management: When managing a fleet of vehicles, knowing the real-time rental of all drivers allows to meet customer needs more efficiently. Whether it is delivery, service or other multi-vehicle enterprises, drivers now only need a mobile phone with telephony or internet connection to be inexpensively tracked by and dispatched efficiently.
- Asset tracking: Asset tracking: Asset tracking: Asset tracking.
- Field service management: Companies with a field service workforce for services such as repair or maintenance, must be able to plan Vehicle tracking allows companies to quickly locate a field engineer and dispatch the closest one to meet a new customer request or provide site arrival information.
- Field sales: Mobile sales professionals can access real-time rentals. For example, in unfamiliar areas, they can locate themselves as well as customers and prospects, get driving directions and add last-minute appointments to itineraries. Benefits include increased productivity, reduced driving time and increased time spent with customers and prospects.
- Trailer tracking: Haulage and Logistics. The part of the vehicle that drives the load is known as the trailer. There are different types of trailer used for different applications, eg, flat bed, refrigerated, curtain sider, box container.
- Surveillance : A tracker may be placed on a vehicle to follow the vehicle’s movements. 
- Transit tracking: temporary tracking of assets or cargoes from one point to another. U-Turn in order to ensure the security of the assets.
- Fuel Monitoring: Fuel Monitoring.
- Distance Calculation: calculate the distance traveled by the fleet.
- OBD II – Plug and play interface which provides most engine diagnostics information.
Vehicle tracking systems are widely used worldwide. Components of GPS technology and GSM services. Additionally, these systems may also feature short range data communication systems such as WiFi . While most will offer real-time tracking, others record real time data and store it to be read, in a fashion similar to data loggers. Systems like these track and record and allow reports after certain points have been solved.
Industries not traditionally known to use vehicle tracking systems (logistics and transportation industries are the ones that have traditionally incorporated vehicle tracking system into their operations) have started to use it in creative ways to improve their processes or businesses.
The hospitality industry has caught on to this technology to improve customer service. For example, a hotel in Singapore has access to the VIPs when they reach the hotel.
Vehicle tracking systems used in food delivery vans may alert if the temperature of the refrigerated compartment moves outside of the range of safe food storage temperatures. Car rental companies are also using their fleets.
