In the utility model in each block the pattern of path intersection can be conventional type formula or preferred (referring to Fig. 5): can only keep straight on and each travel direction can only be turned right when keeping to the right along a direction, when keeping left, can only turn left; Or can not keep straight on (referring to Fig. 6), and can only turn right when keeping to the right, can only turn left when keeping left.
The utlity model has outstanding advantage and effect, motor road of the present utility model system is adopted in the transformation of existing urban road system, and road passage capability can be increased to about four times.This is because the traffic capacity in every track can be brought up to 1800 (when pause in no crossing) from per hour 450 (when need pause in the crossing).If the delay that traffic congestion causes is taken into account, the existing urban road traffic capacity can be lower.
Adopt motor road of the present utility model system, can make on the land area of one unit of city traffic in large supply in the transport need amount, be that traffic is supplied density greater than transport need density, this just can fundamentally eliminate the traffic congestion in bustling urban district, need not to take the restricted driving measure of automobile.
Adopt motor road of the present utility model system, will make the city average speed improve about four times.Automobile runs same distance, and institute's time spent is original 1/4th, and this has just greatly improved the operational paradigm in city.
Adopt motor road of the present utility model system, can make the automobile pollution on every square kilometre of land area improve about four times, so can build up the compact city.This compact city is compared with " the stand large flat bread " in existing city, and the former city floor space is the latter's 1/4th, and the diameter in city reduces half.If take all factors into consideration, average speed is increased to about four times, and the city diameter reduces half, and so, all transfer efficients of the city stream of people, logistics will have great raising.Therefore, with the optimal city size that half an hour, operating range was delimited, will be increased to from 2,000,000 present people more than 2,000 ten thousand people, this development to urban economy is very important.
Adopt motor road of the present utility model system, reduce to original 1/4th as the trip distance of above-mentioned automobile, and can travel continuously.These two combined factors are got up, and the average fuel consumption of automobile will be reduced to original sixth to eight/one, and this energy policy to country is very favourable.
Be not difficult to find out from above analysis, adopt motor road of the present utility model system, in the city, can also form " public traffic in priority " naturally, and can save the investment of public transit system in a large number.
Adopting outstanding effect of motor road system of the present utility model is " bringing order out of chaos ", can pull back the urban highway traffic transformation from a passless the opposite way round.This opposite way round is, only pays attention to the large-engineering of some road constructions and ignores and improve traffic supply capacity on the land area of one unit, ignore the traffic capacity that improves each bar road in the whole road network.Simultaneously, thinking of the present utility model, can correct one is wrong conclusion---" it is impossible blocking up by the transport solution of repairing the roads " that a lot of people accepted.Do not need to build again cost height such as viaduct, big grade separation, occupations of land is many, the traffic capacity is limited means of transportation in the transformation of mature city, avoided building the means of transportation of dismounting possibly in these future.
Adopt motor road of the present utility model system, only transform the intersection, just can excavate the potentiality that are equivalent to about four times of original road passage capabilities, therefore with less investment, the road investment is reduced significantly, is a kind of small investment, easily enforcement, the high technical scheme of repayment.
