UrbanTwinTrain is suitable for cities that are considering building an underground or LRT or that require a public transport capacity of more than 7,000 people per hour. Unlike the underground, it is quicker to implement and much cheaper, both during construction and operation.
By increasing the frequency of trams, the employment time and the number of congested intersections for other traffic participants will increase, which, in turn, will lead to an increase in congestion and, accordingly, the collapse of the entire transport system.
- Example 1:
reducing the intervals of 45-meter trams with priority passage of intersections from 4 to 3 minutes, will cause an increase in traffic jams at intersections at 70% or more;
- Example 2:
sequential movement of two 45-meter trams with priority passage one after another with an interval of 5 minutes will cause their additional stop at each stop for 42 seconds or more, as well as the duration of the prohibition signal at traffic lights for other traffic participants will increase by 53 seconds, and in case of waiting for travel and oncoming tram - 180 seconds or more, which will also cause a transport collapse.
The minimum interval for trams with a length of 67m, having priority passage of intersections, is 4 minutes. With a further decrease in the interval, the busy time and the number of congested intersections for other traffic participants will increase, which, in turn, will lead to an increase in congestion and, accordingly, a collapse of the transport system. If to make trams without priority travel, traffic jams will be formed at traffic lights because of trams with an unacceptable slowdown in their traffic.
Due to the parallel movement of trams and the possibility of increasing the intervals between groups of trains, the number of congestion at intersections is reduced, and the maximum number of passengers transported is doubled.
At the same time:
- at intersections with non-intensive cross-traffic, oncoming pairs of trams are separated without creating significant obstacles to other transport due to its small number;
- at intersections with heavy cross traffic, trams move in pairs along both tracks, occupying a minimum of space and due to this also creating no obstacles to traffic flow.
UrbanTwinTrain initially focused on the Tram and LRT, as the most popular and convenient types of urban rail transport, which significantly reduce the formation of harmful emissions into the urban atmosphere, since such transport does not have emissions of rubber particles and asphalt coating from the friction of wheels against the road, there is no re-formation of dust suspension when driving. A small amount of steel dust formed during the movement of iron wheels along the rails remains within the roadway and is not spread by the wind.
In view of the rapid reaction to the changing passenger traffic in the cities with different population densities, UrbanTwinTrain is applicable both for modern megacities and for large cities with centers of old development. Especially, UrbanTwinTrain is effective for connecting the suburbs with the city center. In this case, there is no need for intercepting parking for cars, there is no loss of time for transplants, and the environment is improving.
Due to the doubling of trains, UrbanTwinTrain allows to increase the volume of ground passenger traffic by 2 times compared to the classic scheme of urban transport without creating additional traffic jams.
To inform passengers, the platforms of stopping points may additionally be equipped with electronic signs with information indicating .
For example, during rush hours, when traffic is organized in groups, the platforms operate in a two-way mode, which is informed by a text or character indication in the form of an inscription or arrow pointing in both directions, or in another understandable way.
Moreover, this electronic signs with information indicating in which direction the following vehicles will move from this platform. Also, the indicating of the direction of movement are installed in trams.
At other times, such an indication displays information that the platforms are operating in a one-way mode, for example, in the form of an arrow pointing in the corresponding direction of movement.
Due to the trams move in pairs simultaneously on two tracks in each direction with priority passage at intersections, they don’t stand at traffic lights and in traffic jams. It takes less time to pick up and drop off passengers, due to the arrival and departure of trams of both stops simultaneously in each direction.
Re-equipment of the existing infrastructure does not require time-consuming reconstruction, construction of racks, tunnels and additional bypass routes. It is enough to equip the the stopping points with turnout, and in the case of the use of BRT (buses) - to provide near the stopping points the confluence of the tracks that arethe lanes of the roadway.
This option is not possible due to the fact that the length of the train cannot exceed the existing standards for the length of the city tram. In addition, by increasing its length, it would be necessary to reconstruct and extend the platforms of stopping points. A long tram can block several intersections during a stop at the platform or at traffic lights, thereby causing congestion and a complete stop at these intersections. This is especially actual in the centers of old cities with dense development. Many stops and some city blocks are not long enough to accommodate more than one 67-meter transport.
UrbanTwinTrain is much less expensive during the construction phase and has a much higher return for investors with a comparable number of passengers transported and speed. UrbanTwinTrain is convenient for the city budget due to the ease of service, reliability and efficiency. It has a rapid reaction to an increase in passenger traffic during rush hours without worsening the road situation. It significantly saves passengers the total time spent on the trip, since passengers do not need to go underground and crowd at the escalators daily losing up to 30 minutes of time. It has increased security, since all the infrastructure is located on the surface of the earth, and not in deep tunnels. The cost of operating trams UrbanTwinTrain much less than the metro.
A controversial idea. The main problem of two decker transport is its safety, landing time, maneuverability, emergency evacuation difficulties and the general inconvenience of using the second decker. And also the restriction of its height, which is relevant both for the quarters of medieval centers and overpasses of modern megacities. But if in some way anybody solves all these problems and make two decker UrbanTwinTrain, it will be able to transport more than 30,000 passengers per hour without complicating the road situation!
Without requiring much investment at the construction stage and high operating costs, UrbanTwinTrain solves the problems of congestion of land public transport and doubles the volume of land passenger traffic without worsening the road situation. Also, when transferring from private to public transport, the costs of constantly building a huge number of parking spaces are excluded.
Firstly, modern public rail transport is beautiful in itself, secondly, the isolation of tracks from other transport gives the urban landscapes spatial freedom, and thirdly, to re-equip the existing infrastructure requires minimal reconstruction measures, which does not violate the appearance of both the modern center of the metropolis and the narrow parts of medieval centers. Moreover, comfortable salons, panoramic windows and smooth movement make the travel in the car akin to an exciting excursion. In the fourth, the transition from a private car to public transport will significantly improve the environmental situation in the city.
The amount of electricity consumed will be proportional to the number of trams involved in the operation, thanks to the use of the same trains as in the usual ways of traffic organizing.
A large number of private vehicles, even unmanned, on the road is a big problem. Traffic jams from such a decision will only increase, because one tram is able to carry about 460 passengers, which corresponds to an average of 300-350 cars that will have to allocate additional space on the roadway. Thus, the number of transport on the city's roads will increase tenfold and even the use of unmanned systems in the future for faster crossings will not reduce their congestion. In addition, ecology will still be in a deplorable state: it is known that the share of exhaust emissions of modern internal combustion engines equipped with cleaning systems is small in relation to the emissions of harmful rubber particles and dust from the friction of wheels against asphalt. Thus, even by using electric vehicles and eliminating emissions, we will not reduce traffic jams, not improve the environmental situation and not reduce the overall background of urban pollution.
Perfect solution!
UrbanTwinTrain will easily bring passengers to the nearest metro station or station platform, thus connecting the suburbs and the multicenter city into a single transport system.
UrbanTwinTrain is the latest solution to the old transport problems of megacities. The system is currently in the design, improvement and preparation phase for implementation.
