A few systems integrate (or communicate) with mobile phones for hands-free talking and SMS messaging (i.e., using Bluetooth or Wi-Fi). Automotive navigation systems can include personal information management for meetings, which can be combined with a traffic and public transport information system.
Direction indicator lights [23] or turn signals, [11] informally known as directional signals, directionals, blinkers, or indicators, are blinking lights mounted near the left and right front and rear corners of a vehicle, and sometimes on the sides or on the side mirrors of a vehicle (where they are called repeaters [50]).
The final complete system came in 1927 when Berlin-based Max Ruhl and Ernst Neuman combined internal illumination and solenoid operation: (but see Gladstone Adams). The shape of the trafficator arm is closely based upon the shape of the semaphore signal arm used by the Royal Bavarian State Railways beginning in 1890.
Vehicular communication systems are computer networks in which vehicles and roadside units are the communicating nodes, providing each other with information, such as safety warnings and traffic information. They can be effective in avoiding accidents and traffic congestion.
Richard Bowie Spikes (October 2, 1878 – January 22, 1963) was an African-American inventor who held several United States patents. He is credited with developing and improving inventions such as a beer tap, a modification of an automatic gear shift mechanism for motor vehicles, and a safety braking system for trucks and buses.
The modern systems are called goniometers by analogy to WW II directional circuits used to measure direction by comparing the differences in two or more matched reference antennas' received signals, used in old signals intelligence (SIGINT).
A navigation system is a computing system that aids in navigation. Navigation systems may be entirely on board the vehicle or vessel that the system is controlling (for example, on the ship's bridge) or located elsewhere, making use of radio or other signal transmission to control the vehicle or vessel. In some cases, a combination of these ...
The development of automobiles encouraged more complex signage systems using more than just text-based notices. One of the first modern-day road sign systems was devised by the Italian Touring Club in 1895. By 1900, a Congress of the International League of Touring Organizations in Paris was considering proposals for standardization of road ...
