The invention relates to transport systems that use a dedicated transport route, placed above the ground.

A known system of cable transport in which vehicles are driven by stationary power units, providing the motion of the actuators, which are mounted on a vehicle having wheel base /Berkman, M. B. "chairlift" engineering, 1984/.

Such systems allow to overcome steep grades, but their placement is only possible on the straights, and the engine power must be sufficient to move and the vehicle is long and heavy, carrying the traction rope.

Closest to the proposed is the road transport system, including road highlighted path with a variable slope, a driving device, a power plant and wheeled vehicles.

In such a system on selected routes with variables, including large, slope, moving wheeled carriages special design that allows to overcome the large gradients in the horizontal position of the crew. While these wheeled vehicles moving along the path through installed on them, Electromechanical actuator, which operates from either catenary or placed n� vehicle propulsion /Patent RF №2332311, CL B60F 1/00, publ. 27.08.2007./.

The closest is the transport system, which includes mounted on the rack rails with alternating short long shallow climbs and descents and ability to move the vehicle down a slope not less than 0.3% by the gravitational force, and a driving device with a stationary source of food placed on short ascents /US 7527000 D2 (Gerad Adam), 05/05/2009/.

The disadvantage of such systems is the need for expensive contact network or stand-alone power unit and the actuator, which is placed on a wheeled vehicle, which increases its mass, and therefore leads to additional energy consumption for the movement. In addition, the transport system, the principle of using gravity, not adapted for rubber-tired vehicles that do not provide the possibility of their maneuver, messages with street cars and handling outside the ways, have a significant share of the crews, which requires the construction of flyovers with high load capacity.

The technical challenge is to reduce energy consumption in the operation of wheeled vehicles and the reduction of costs for the construction of the road transport system by reducing the mass of wheeled vehicles.

Post�run the problem is solved so in the road transport system, comprising mounted on the overpass highlighted path with alternating rises and gentle slopes to move the vehicle down a slope under gravity, the driving device from stationary power sources and vehicles, according to the invention mounted on the overpass dedicated road route from alternating areas with lifts that have a bias 18-75%, and slopes that have a gradient of not more than 6%, this traffic system is equipped located in areas with gentle slope outside of dedicated lines and United with them terminals for entry and exit of wheeled vehicles from the system on a street road. In addition, a wheeled vehicle may be equipped with mounting brackets for connection with a lifting driving device. When mounted on the track section with the steep rise of the lifting driving device can be performed with a mechanical actuator mounted on the section of track with a steep climb of the lifting driving device can be performed with electromagnetic drive. Moreover, the terminals for entry and exit of wheeled vehicles can be connected to the terminals of the storage of wheeled vehicles and/or terminals for loading and unloading. Besides lifting� the driving device on a plot with a steep climb can be made in the form of platform mounted with the possibility of loading it wheeled vehicle.

The proposed traffic system differs from the known fact that the rack mounted dedicated road route from alternating areas with lifts that have a bias 18-75%, and slopes that have a gradient of not more than 6%, with road and transport system is provided located in areas with gentle slope outside of dedicated lines and United with them terminals for entry and exit of wheeled vehicles from the system on a street road.

This traffic system is designed to transport wheeled vehicles small mass of both people and goods. In the proposed system wheeled vehicles can move only on marked paths, and can leave the system and move through the streets, if they have their own drive and control mechanism. As wheeled vehicles can be used a wheeled platform, electric cars and pedal cars of special design, as well as ordinary individual vehicle.

The parameters of the gradient ascent is selected from the condition of horizontal orientation of the vehicle during its movement up the gradient should not exceed the coefficient of friction between the material of the wheels t�ansporting funds and travel selected routes. Options gentle descent selected from the condition of the coefficient of friction of the wheel of the vehicle and the road surface and speed limit, which amounts to 6%.

Spans of trestle are made of steel or composite (steel-concrete, fiber reinforced concrete, fiberglass, carbon fiber, etc.) and beam frame or combined system and expect loads from light wheeled vehicles.

The technical result is that the movement in the system is due to the rise of wheeled vehicles on the rise of the external driving device with its subsequent movement of the trigger with the possibility of maneuver due to gravity. This allows you to arrange on the overpass of a contact network, which reduces its cost. When driving on a downhill is not required to expend energy, and that means a wheeled vehicle may not be powerful, and consequently, heavy engine with the drive and not carry energy in the form of batteries, having a greater weight and cost. Relief vehicle allows to reduce the consumption of energy to overcome friction forces. The low weight of the vehicle reduces the load on the flyover, which in turn reduces the consumption of materials for its construction.

This embodiment of the system expansion�splash zones communication highway between himself and settlements provides optimal traffic organization.

Fig.1 shows a traffic system, side view; Fig.2 and 3 the same as in Fig.1, a top view (run terminal).

The road transport system consists of racks with dedicated routes with areas 1 with a gentle slope and a phase 2 with a steep climb, 3 wheeled vehicles, the driving device 4 mounted on the section 2 racks, and stationary power units 5.

A traffic system according to the invention includes at least one multi-span viaduct with areas 1 and 2 respectively, with a gentle slope with a gradient of 6% and a steep climb with gradients 18-75%, which allows wheeled vehicles 3 to move along the plot of 1 downhill due to gravity at an estimated rate of 2-12 m/s. In the case of the application of additional thrust wheeled vehicle can move faster. The length of the section 1 of the overpass is hundreds of meters, she can pass over different obstacles and requires minimal land acquisition to accommodate the supports. Phase 2 of the overpass has a small length. Section 2 of the overpass wheeled vehicle 3 is delivered to the upper point of phase 1 of the overpass at the expense of moving along the overpass 2 lifting driving device 4, which may be with the tavern�electric or electromagnetic drive.

For lifting the driving device is used as a stationary power installation 5, which is located near the overpass at site 2. Stationary power unit may be an electric, mains-or offline, including consisting of devices for energy generation and energy storage. When climbing the flyover phase 2 wheeled vehicle 3 is transferred to potential energy, which it uses when driving down the steep hill to overcome friction and air resistance. Therefore, it is not necessary to provide a powerful engine and transmission, which can significantly reduce the weight of the wheeled vehicle.

If 3 wheeled vehicle can only move in the proposed system, then they do not have their own drive and are automatically operated, transporting passengers or cargo from point of loading to point of discharge. For Parking unused 3 wheeled vehicles in the road transport system provides terminals, storage devices 6 that are located outside the primary path that is used for movement, and are connected with dedicated paths trestle section 1.

If 3 wheeled vehicle must move as in the proposed system, and on normal roads, then they are supplied with additional property�military drive and control mechanism for the driver and the road transport system is complemented by the terminals 7 and 8, respectively - ways for entry and exit must be positioned on the approach to stations 2 overpasses (see Fig.3/.

The road transport system for different types of vehicles can be combined on the same trestle sections 1 and 2, including the location in several levels.

Wheeled vehicle 3 enters the path of the road transport system from the terminal storage device 6, from the point of loading 9 or comes back through the terminal entry 8. Next wheeled vehicle is connected with the lifting driving device 4, which moves it by section 2 of the overpass with a steep climb to the top and leaves him there to advance the trigger on a plot of 1 trestle with a gentle slope. This movement occurs uniformly under the action of gravity and friction and resistance of air. Depending on the desired rate is selected, the slope of the plot of 1 overpass and additional traction force. Having moved down from the plot of 1 ramps, wheeled vehicle may continue to rise in the next section 2 trestles with a lifting driving device 4, to enter the terminal loading and unloading 9 or in the terminal storage 6 or leave the system through the terminal, exit 7. The choice is determined by voditeleml program the management movement.
