A process trailer, also known as insert trailer and low loader, is a trailer towed by a tracking vehicle for the purpose of being used as a moving camera platform. [1] They are generally very low to the ground to give a realistic perspective of height and can be expanded in width to allow the camera to achieve a wider shot. Process trailers are most often used to shoot dialogue scenes inside cars or other vehicles while reducing risk for actors who would otherwise drive while delivering lines.
The trailer is composed of a wheeled platform, low to the ground, with the vehicle secured on top. The vehicle on the platform is known as a "picture car". The platform itself is then towed by another vehicle with crew members and camera equipment to film the actors in the vehicle. [2] Although process trailers are safer for actors, there is still a significant risk to the driver and passengers of the towing vehicle - for this reason, process trailers are often led by a police vehicles to prevent traffic accidents. In Australia, process trailers must be accompanied by police and may only be used with a permit. [3]
A beacon is an intentionally conspicuous device designed to attract attention to a specific location. A common example is the lighthouse, which draws attention to a fixed point that can be used to navigate around obstacles or into port. More modern examples include a variety of radio beacons that can be read on radio direction finders in all weather, and radar transponders that appear on radar displays.
A semi-trailer truck is the combination of a tractor unit and one or more semi-trailers to carry freight. A semi-trailer attaches to the tractor with a type of hitch called a fifth wheel.
In cinematography, a tracking shot is any shot where the camera follows backward, forward or moves alongside the subject being recorded. Mostly the camera’s position is parallel to the character, creating a sideway motion, tracking the character. Tracking shots differ in motion from dolly shots, where the camera follows behind or before the character resulting in either an inward or an outward movement. Often the camera is mounted on a camera dolly which rides on rails similar to a railroad track; in this case, the shot is referred to as a dolly shot. A handheld steadycam or gimbal may also be used for smaller scale productions. The camera is then pushed along the track while the scene is being filmed, or moved manually when using a handheld rig. The effect can be used to create a sense of movement, to follow a character or object, or a sense of immersion to draw the viewer into the action.
A stunt is an unusual, difficult, dramatic physical feat that may require a special skill, performed for artistic purposes usually for a public audience, as on television or in theaters or cinema. Stunts are a feature of many action films. Before computer-generated imagery special effects, these depictions were limited to the use of models, false perspective and other in-camera effects, unless the creator could find someone willing to carry them out, even such dangerous acts as jumping from car to car in motion or hanging from the edge of a skyscraper: the stunt performer or stunt double.
A recreational vehicle, often abbreviated as RV, is a motor vehicle or trailer that includes living quarters designed for accommodation. Types of RVs include motorhomes, campervans, coaches, caravans, fifth-wheel trailers, popup campers, and truck campers.
The Ford Explorer is a range of SUVs manufactured by Ford Motor Company since the 1991 model year. The first five-door SUV produced by Ford, the Explorer was introduced as a replacement for the three-door Bronco II. As with the Ford Ranger, the model line derives its name from a trim package previously offered on Ford F-Series pickup trucks. As of 2020, the Explorer became the best-selling SUV of all time in the American market.
A trailer is an unpowered vehicle towed by a powered vehicle. It is commonly used for the transport of goods and materials.
The Ford Expedition is a full-size three-row SUV, manufactured and marketed by Ford over four generations since model year 1997, deriving directly from Ford's concurrent generations of its F-150 pickup truck—and marketed since 2007 in regular and extended lengths, the latter replacing the Ford Excursion. Since 1997, Ford's Lincoln brand has marketed a rebadged variant of the Expedition, as the Lincoln Navigator.
A car chase or vehicle pursuit is the vehicular overland chase of one party by another, involving at least one automobile or other wheeled motor vehicle, commonly hot pursuit of suspects by law enforcement. The rise of the automotive industry in the 20th century increased car ownership, leading to a growing number of criminals attempting to evade police in their own vehicle or a stolen car. Car chases may also involve other parties in pursuit of a criminal suspect or intended victim, or simply in an attempt to make contact with a moving person for non-conflict reasons.
The Jeep Grand Cherokee is a range of mid-size SUVs produced by the American manufacturer Jeep. At its introduction, while most SUVs were still manufactured with body-on-frame construction, the Grand Cherokee has used a unibody chassis from the start.
A tow truck is a truck used to move disabled, improperly parked, impounded, or otherwise indisposed motor vehicles. This may involve recovering a vehicle damaged in an accident, returning one to a drivable surface in a mishap or inclement weather, or towing or transporting one via flatbed to a repair shop or other location.
A police car is a ground vehicle used by police and law enforcement for transportation during patrols and responses to calls for service. A type of emergency vehicle, police cars are used by police officers to patrol a beat, quickly reach incident scenes, and transport and temporarily detain suspects, all while establishing a police presence and providing visible crime deterrence.
An automated guided vehicle (AGV), different from an autonomous mobile robot (AMR), is a portable robot that follows along marked long lines or wires on the floor, or uses radio waves, vision cameras, magnets, or lasers for navigation. They are most often used in industrial applications to transport heavy materials around a large industrial building, such as a factory or warehouse. Application of the automatic guided vehicle broadened during the late 20th century.
Road speed limit enforcement in Australia constitutes the actions taken by the authorities to force road users to comply with the speed limits in force on Australia's roads. Speed limit enforcement equipment such as speed cameras and other technologies such as radar and LIDAR are widely used by the authorities. In some regions, aircraft equipped with VASCAR devices are also used.
Towing is coupling two or more objects together so that they may be pulled by a designated power source or sources. The towing source may be a motorized land vehicle, vessel, animal, or human, and the load being anything that can be pulled. These may be joined by a chain, rope, bar, hitch, three-point, fifth wheel, coupling, drawbar, integrated platform, or other means of keeping the objects together while in motion.
A flatbed truck is a type of truck the bodywork of which is just an entirely flat, level 'bed' with no sides or roof. This allows for quick and easy loading of goods, and consequently they are used to transport heavy loads that are not delicate or vulnerable to rain, and also for abnormal loads that require more space than is available on a closed body. Flatbed trucks can be either articulated or rigid.
A motorcycle trailer is either a trailer used to carry motorcycles or one to be pulled by a motorcycle in order to carry additional gear.
Vehicle impoundment is the legal process of placing a vehicle into an impoundment lot or tow yard, which is a holding place for cars until they are placed back in the control of the owner, recycled for their metal, stripped of their parts at a wrecking yard or auctioned off for the benefit of the impounding agency.
Vehicle recovery is the recovery of any vehicle to another place, generally speaking with a commercial vehicle known as a recovery vehicle, tow truck or spectacle lift.
Smart cities seek to implement information and communication technologies (ICT) to improve the efficiency and sustainability of urban spaces while reducing costs and resource consumption. In the context of surveillance, smart cities monitor citizens through strategically placed sensors around the urban landscape, which collect data regarding many different factors of urban living. From these sensors, data is transmitted, aggregated, and analyzed by governments and other local authorities to extrapolate information about the challenges the city faces in sectors such as crime prevention, traffic management, energy use and waste reduction. This serves to facilitate better urban planning and allows governments to tailor their services to the local population.
