Automatic vehicle location

This vehicular network diagram example was drawn on the base of picture illustrating the article "Automatic Vehicle Location: Rural Transit" from the website of the Research and Innovative Technology Administration (RITA), U.S. Department of Transportation (US DOT).
"Automatic Vehicle Location (AVL) systems calculate the real-time location of any vehicle equipped with a Global Positioning Satellite (GPS) receiver. Data are then transmitted to the transit center with use of radio or cellular communications and can be used immediately for daily operations as well as archived for further analysis.
As a stand-alone technology, an AVL system can be used to monitor on-time performance. When combined with other technologies, AVL can deliver many benefits in the areas of fleet management, service planning, safety and security, traveler information, fare payment, vehicle component monitoring, and data collection. Since the greatest benefits from AVL are achieved by combining it with other Intelligent Transportation System (ITS) technologies, AVL is most appropriate for large rural agencies with more than 30 vehicles that plan to implement a comprehensive ITS."

"Driving is the controlled operation and movement of a vehicle, such as a car, carriage, truck or bus. ...
Driving as a physical skill.
A driver must have physical skills to be able to control direction, acceleration, and deceleration. For motor vehicles, the detailed tasks include:
(1) Starting the vehicle's engine with the starting system.
(2) Setting the transmission to the correct gear.
(3) Depressing the pedals with one's feet to accelerate, slow, and stop the vehicle, and if the vehicle is equipped with a manual transmission, to modulate the clutch.
(4) Steering the vehicle's direction with the steering wheel.
(5) Operating other important ancillary devices such as the indicators, headlights, and windshield wipers.
(6) Observing the environment for hazards." [Driving. Wikipedia]

"Vehicular Ad Hoc Networks (VANETs) are created by applying the principles of mobile ad hoc networks (MANETs) - the spontaneous creation of a wireless network for data exchange - to the domain of vehicles. They are a key component of intelligent transportation systems (ITS).
While, in the early 2000s, VANETs were seen as a mere one-to-one application of MANET principles, they have since then developed into a field of research in their own right. By 2015, the term VANET became mostly synonymous with the more generic term inter-vehicle communication (IVC), although the focus remains on the aspect of spontaneous networking, much less on the use of infrastructure like Road Side Units (RSUs) or cellular networks."

This vehicular network diagram sample was drawn on the base of picture illustrating the post "Intelligent transportation system" from the blog "Technology New Here".
"Intelligent transportation systems are projects that aim to integrate modern communication and information technology into existing transportation management systems in order to optimize vehicle life, fuel efficiency, safety, and traffic in urbanized cities.
The need for intelligent transportation systems stems from the fact that traffic congestion has been increasing all around the world because of increasing population, increasing amount of transportation vehicles and increasing urbanization."

The vector stencils library "Transport map" contains 96 signs and pictograms for drawing road and transit maps.
"A transit map is a topological map in the form of a schematic diagram used to illustrate the routes and stations within a public transport system - whether this be bus lines, tramways, rapid transit, commuter rail or ferry routes. The main components are color coded lines to indicate each line or service, with named icons to indicate stations or stops.
Transit maps can be found in the transit vehicles, at the platforms or in printed timetables. Their primary function is to help users to efficiently use the public transport system, including which stations function as interchange between lines. Unlike conventional maps, transit maps are usually not geographically accurate - instead they use straight lines and fixed angles, and often illustrate a fixed distance between stations, compressing those in the outer area of the system and expanding those close to the center."
