Polution:
Traction is electric.
- No exhaust gases! No polution from the many vehicles themselves.
- The degree of polution is stipulated by the way electricity is supplied out of other energy sources (Green energy or not)
Energy:
- Het guideway cab uses per kilometer much less energy. How much is strongly connected to the comparing system. The welsh system Utra, for instance, uses only a quart of a car in the city.
- The energy usage is limited because a guideway vehicle drives at constant speed and because there are no intermitting stops. And, with several guideway cab systems, energy recovery can take place at slowing down.
- The �law of conservation of travel times and numbers of of displacements� (BReVer) tells us that people are traveling approximately 430 hours in one year. As the travel speeds will increase by faster guideway cabs, the traveled distances will also become larger. If the guideway cab as a result of this still will save energy is an unanswered question at the moment.
- The energy usage of a transport means is generally expressed in the number of kilometres with a quantity of energy. (for instace: 20km with 1liter of fuel). In this respect however, energy usage can be better expressed in the travel time per quantity of energy. (for example 6 minutes by a kiloWatt)
Noise:
The quantity of sound is stipulated by the sound of the engine, the speed and intensity of the traffic, the pavement and how easy the sound can spread itselfs. How is this with guideway cabs?
- The engine sound of guideway cabs is very small, thanks to the small electric motors. This in contrast to the heavy combustion motors of lorry traffic, buses, engines and brommers. Also the number of times to brake and to accelerate is much times hgher than by guideway cabs. Braking and accelerating produces extra noise, which is avoided with guideway cabs.
- All guideway cabs drives at the same speed and their maximum speed is as a result nearly the same as the average speed. At the traffic of road traffic on the other hand, a part of the vehicles drives faster than the everage speed. These vehicles however, causes most of the noise. Also to overcome the waisted time because of traffic lights and so on, a high driving speed is needed to obtain a reasonable average speed. And that speed is what produces most of the noise above the noise at average speed.
- The intensity of guideway traffic can be higher than traffic on ordinary roads. More traffic produces more sound. On the other hand there will be no extra noise caused by speed differences and vehicles passing by.
- The pavement of the guideway is smooth metal or smooth concrete, over which wheels hits with smooth rubber tyres. That ensures very little sound. In contrast to clinker roads, grind asphalt ways or cobblestone ways which cause much more noise a vehicle. Even steel on steel like railways ensures more noise than rubber on steel or on concrete.
- The guideway cab wheels are riding in a more or less closed guideway. The sound is locked up in the guideway and cannot this way easy spread itself into the surroundings. At road- and rail traffic the produced noise is free to spread itsels to all sides.
- The guideway itself can, caused by many wheels, vibrate. This is very depending of the design of the guideway. Probably there will be further and further design proces over a long period. Interesting isn�t it?
Conclusion: Guideway traffic is audiblely quieter than road- and rail traffic.
Light polution:
Light clogging is light that shines at night on places, where it normally must be dark. Examples of this are: slepingrooms, nature reservates and places where man wants to look at stars. Light clogging is caused (among other causings) by traffic. Street bulps, car lamps at front and rear, braking lights, traffic lights and signals. All of this is not used with guideway cabs. Guideway cab, however has other light emitting objects: the stations and the many cabins are lighted. But the shining of light out of the cabins is better to avoid than car lights because the light has no task outside the cabin like car lights.
Depletion of raw materials
The guideway cab needs less use of raw meterials than ardinairy cars. This is mainly because guideway cabs are used by more persons than cars normally do. Multiplied if the cabs has a longer lifecycle.
Other environment items:
Guideway cabs do not splash wet pedestrians and bikers. Guideway traffic don�t ride on roads with padles, they drives along quideways with are harnassed against weather. (at most of the systems)
Empty vehicles is a problem of guideway traffic. Because the vehicles drives themselves to a station, where they are wanted or will be wanted in time. It is a consequence of an uneven partitioning of travellers demand. This phenomenon occurs at all public transport systems. An example is a ski-lift: the barges come empty down. Even at cars occur drive without payload. No ones sees it, because always a diver is neede. Some examples? Drive the car to the garage for repair, going to refuel, drivers lessons, not carpooling only because the retour trip differs from each other, the retour trip when you bring someone home, or the first trip if you get someone from the station. And of course the searching trip to a free parking place. |
