Engineering - transportation

2- Background Art: -

Most road service and emergency vehicles are big trucks and occupy a lane to complete its duty, there are many kinds of road services needed daily to ensure road safety and good performance example road cleaning vehicles, ambulance, firefighting trucks, police cars, roads and lighting poles maintenance vehicles and etc. some of this vehicle examples (road cleaning vehicles) travel with speed lower than the premised road speed to complete its task.

Also, some road services vehicles example vehicle used for street lighting and road signs maintenance to complete its work it must stop on road consuming a lane, that Led to decrease in the road capacity and efficiency to transport the traffic flow required.

Also, during road accidents with injuries or fire on the road, most of this accident leads to traffic jam or complete closure of the road that hinders sometimes prevents ambulances and firefighting vehicles from reaching the accident area at the speed required to transport the injured or to extinguish the fire.

Therefore, there is a need to invent a new method of transportation that does not required to use the road lanes to perform the necessary services, such as cleaning the roads without affecting the road capacity, as well as for transporting the injured and fire extinguishing inaccidents, even in cases of severe traffic congestion or in rush hours.

Therefore, a small means of transportation was invented that uses the road concrete barriers as a track as these barriers already extended along the road’s length (beside its original function as a barrier between road directions and a bumper for drifted cars) to be used in emergency specially in cases where the ordinary emergency trucks cannot reach and also can be used for different road daily services without affecting the road capacity and efficiency.

2-1 The problem or deficiency in previous art:

In the previous art, the roads need to be served by ambulances, firefighting trucks, waste collection and other maintenance services that required to be carried out using large trucks and vehicles:

1- During the waste collection services the waste collection and road cleaning vehicle travel with speed lower than the road speed to complete its task that led to reduction in the road capacity and efficiency.

2- In the case of road and light poles maintenance the vehicles used required to stop to complete its work consuming lane from the road that led to reduction in road capacity and efficiency during the maintenance period.

3- during road accidents with injuries or fire on the road, most of this accident leads to traffic jam or complete closure of the road that hinders sometimes prevents ambulances and firefighting vehicles from reaching the accident area at the speed required to transport the injured or to extinguish the fire

3- Disclosure of Innovation

3-1 New in the subject of the invention: -

The new in the subject of the invention is designing a new means of transportation that uses the road concrete barriers (beside its original function) that are already extending along the road’s length as a track for the introduced small vehicle that move using the roads concrete barriers as track on both road sides to be used in emergency cases and for road daily service duties.

3-2 Detailed Description: -

Establishing a new small in size means of transportation using the road concrete barriers on both sides as an existing infrastructure that can be as a track for the vehicle wheels on the top of the concrete barrier and also using the vehicle support wheels in horizontal directions to establish balance on the track and also to fit different widths of the concrete barriers as shown in the drawings. the vehicle designed to be compact and to moves over the road concrete barrier , its width is less than the road shoulder width so it is designed to not affect the movement of cars on the roads and does not affect the road capacity and function.

3-3 Method of exploitation: -

The new vehicle designed to be used in different road services during traffic jam time or even during traffic obstruction due to emergency case example in accidents cases when the traditional service and emergency trucks cannot reach and work due to traffic jam or during traffic obstruction.

The new road concrete barrier vehicles can be used as a new transportation way to do different duties and services example can work as a small ambulance or for road cleaning and maintenance or as firefighting vehicle.
