Transportation in Los Angeles – Wikipedia

complex multimodal regional, national and international hub for passenger and freight traffic

Los Angeles has a complex multimodal transportation infrastructure, which serves as a regional, national and international hub for passenger and freight traffic. The system includes the United States’ largest port complex; an extensive freight and passenger rail infrastructure, including light rail lines and subway lines; numerous airports and bus lines; Transportation Network Companies; and an extensive freeway and road system. People in Los Angeles rely on cars as the dominant mode of transportation,[1] but since 1990 Los Angeles Metro Rail has built over one hundred miles (160 km) of light and heavy rail serving more and more parts of Los Angeles.

Police car – Wikipedia

A police car (also called a police cruiser, police interceptor, patrol car, cop car, prowler, squad car, radio car, or radio motor patrol (RMP) ) is a ground vehicle used by police for transportation during patrols and to enable them to respond to incidents and chases. Typical uses of a police car include transporting officers so they can reach the scene of an incident quickly, transporting and temporarily detaining suspects in the back seats, as a location to use their police radio or laptop or to patrol an area, all while providing a visible deterrent to crime. Some police cars are specially adapted for certain locations (e.g. traffic duty on busy roads) or for certain operations (e.g. to transport police dogs or bomb squads). Police cars typically have rooftop flashing lights, a siren,

Vehicle leasing – Wikipedia

Vehicle leasing or car leasing is the leasing (or the use) of a motor vehicle for a fixed period of time at an agreed amount of money for the lease. It is commonly offered by dealers as an alternative to vehicle purchase but is widely used by businesses as a method of acquiring (or having the use of) vehicles for business, without the usually needed cash outlay. The key difference in a lease is that after the primary term (usually 2, 3 or 4 years) the vehicle has to either be returned to the leasing company or purchased for the residual value.

Rationale[edit]

Vehicle leasing offers advantages to both buyers and sellers. For the buyer, lease payments will usually be lower than payments on a car loan would be. Any sales tax is due only on each monthly payment, rather than immediately on the entire purchase price

Alternator (automotive) – Wikipedia

Alternator (silver) mounted on a V8 engine

Alternators are used in modern automobiles to charge the battery and to power the electrical system when its engine is running.

Until the 1960s, automobiles used DC dynamo generators with commutators. With the availability of affordable silicon diode rectifiers, alternators were used instead. This was encouraged by the increasing electrical power required for cars in this period, with increasing loads from larger headlamps, electric wipers, heated rear windows and other accessories.

History[edit]

The modern type of vehicle alternators were first used by the military from WWII, to power radio equipment on specialist vehicles.[i] Post-war, other vehicles with high electrical demands, such as ambulances and radio taxis, could also be fitted with optional alternators.[1]

Alternators were first introduced as standard equipment on a production car by the Chrysler Corporation on the Valiant in 1960, several years ahead of Ford

Service (motor vehicle) – Wikipedia

Periodic maintenance of a motor vehicle

A motor vehicle service or tune-up is a series of maintenance procedures carried out at a set time interval or after the vehicle has traveled a certain distance. The service intervals are specified by the vehicle manufacturer in a service schedule and some modern cars display the due date for the next service electronically on the instrument panel. A tune-up should not be confused with engine tuning, which is the modifying of an engine to perform better than the original specification, rather than using maintenance to keep the engine running as it should.

The completed services are usually recorded in a service book upon completion of each service. A complete service history usually adds to the resale value of a vehicle.

Scheduling[edit]

The actual schedule of car maintenance varies depending on the year, make, and model of a car, its driving

Automotive design – Wikipedia

Automotive design is the process of developing the appearance, and to some extent the ergonomics, of motor vehicles, including automobiles, motorcycles, trucks, buses, coaches, and vans.

The functional design and development of a modern motor vehicle is typically done by a large team from many different disciplines included within automotive engineering, however, design roles are not associated with requirements for Professional or Chartered-Engineer qualifications. Automotive design in this context is primarily concerned with developing the visual appearance or aesthetics of the vehicle, though it is also involved in the creation of the product concept. Automotive design as a professional vocation[1] is practiced by designers who may have an art background and a degree in industrial design or transportation design.
Terminology used in the field is found in the glossary of automotive design.

Bicycle Race – Wikipedia

Bicycle Race” is a single by the British rock band Queen. It was released on their 1978 album Jazz and written by Queen’s lead singer Freddie Mercury. It was released as a double A-side single together with the song “Fat Bottomed Girls”. The song is notable for its video featuring a bicycle race with nude women at Wimbledon Stadium, which was controversial at the time, with the video being edited or even banned in several countries.

Composition[edit]

The song was written by Freddie Mercury and was inspired by watching the 18th stage of the 1978 Tour de France passing Montreux, where the band were recording Jazz in the Mountain Studios.[2][3] It starts with a chorus unaccompanied by instruments. The chorus is followed by two verses connected with a bridge, both followed by a chorus. Around the middle of the song is a solo

Hybrid bicycle – Wikipedia

Hybrid bicycles blend characteristics from more specialized road bikes, touring bikes and mountain bikes.[1] The resulting “hybrid” is a general-purpose bike that can tolerate a wide range of riding conditions and applications. Their stability, comfort and ease of use make them popular with novice cyclists, casual riders, commuters, and children.

Hybrids typically borrow the flat, straight handlebars and upright seating posture of a mountain bike, which many bicyclists find comfortable and intuitive. Hybrids also employ the lighter weight, thinner wheels and smooth tires of road bikes, allowing for greater speed and less exertion when riding on the road. Hybrid bikes often have places to mount racks and bags for transporting belongings, much like a touring bike.

Hybrid bikes have spawned numerous sub-categories satisfying diverse ridership. They are classified by their design priorities, such as those optimized for comfort or fitness — and those offered as city, cross or commuter

A moped-style e-bike: an A2B Bicycles Ultramotor metro/octave

An electric bicycle also known as an e-bike is a bicycle with an integrated electric motor which can be used for propulsion. Many kinds of e-bikes are available worldwide, from e-bikes that only have a small motor to assist the rider’s pedal-power (i.e. pedelecs) to more powerful e-bikes which are closer to moped-style functionality. All retain the ability to be pedalled by the rider and are therefore not electric motorcycles.

E-bikes use rechargeable batteries and the lighter ones can travel up to 25 to 32 km/h (16 to 20 mph), depending on local laws, while the more high-powered varieties can often do more than 45 km/h (28 mph). In some markets, such as Germany as of 2013, they are gaining

Public transport – Simple English Wikipedia, the free encyclopedia

Public transport (public transportation in the United States) is the transport of passengers. Passengers don’t need their own cars or other vehicles. Most public transport lets many people travel at the same time.

Ships have carried passengers since prehistoric times. Early public transport by land became important in some places in western Europe in the early 19th century. Around 1826 horsedrawn omnibuses operated in Nantes, France. Omnibuses were carts with seats for passengers to sit. About the same time, railroads began carrying passengers between towns in England. Ferries (public boats) also became bigger and more numerous then.

The main vehicles for public transport are buses, trolleybuses, trams and trains. Trams were first used in the late 1860s and used to be pulled by horses. Now trams are electric and run on a line of cable. Buses drive on the road, like cars do. Trolleybuses are like buses, but they
