XII Status and challenge of the development of solid garage FU CuiYu, GUAN jingtai(Tongji University Mechatronic Institute, Shanghai202092,China) [Abstract ] In thruth,solid garage will propress along with many limit factories although it can remarkably improve the status of parking in China. In this paper ,the chance and frustration of solid garage’s development is analyzed Key words: Number。s demands. of the threedimensional garage With the rapid development of Shanghai, the settlement of the difficult problem of parking of Shanghai has already reached the very urgent stage. In the city center where every inch of land is precious, especially the area which such vehicles as the hotel, market, shopping center location,etc. : concentrate, can only develop to the sky, to underground, so has built and already to a great deal of threedimensional garage parkings reached the essential stage, at the same time there are many adva ntages too in the threedimensional garage parking.. First, economize the space. Generally speaking, its floor space is about 1/2/25 of the level parking area, machinery type Threedimensional The garage can both be installed with the ground underground, the greatest advantage can fully utilize the small area to develop to the high altitude, try one39。t be plete yet either. People should have a course accepted progressively, people have not totally accepted advantage to the threedimensional garage yet, especially to the drivers of some new hands, the required trickcycling of threedimensional garage is higher than garage on the ground, enable some clans owning cars to expect to the threedimensional storehouse that but it is timid to grow. Secondly, citizen longterm consciousness either very difficult to change within short time, have proclaimed in writing to forbid the vacant lot in the roadside to park, but can still see and park in violation of rules and regulations everywhere in the streets and lanes. Because everybody thinks, the street is the public place, it is naturally to park the car above by oneself, why park the car inside the garage, pay the money. Obviously this citizen with the car of part has only emphasized one39。clock, therefore a vicious circle that produces is its immediate cause. The threedimensional garage has not been popularized yet now, the existence of a large number of ground garages makes it not preponderate in price. Maintenance at ordinary times of threedimensional garage is both more costly than the garage parking of road surface with maintaining, so the country will all be relatively high when make the price, the price determines the market, so has caused the long term vacancy of parking stall of threedimensional garage, the management of some largescale threedimensional garage es to make out a bill, investing 224 existing parking stalls of threedimensional garage at 2700 more than ten thousand yuan, probably 200 cars park in one day, average each car park one hour, park 7 per hour, business ine in 3000 yuan about。s investment can not get the corresponding repayment, the great investment enthusiasm of attacking them, the management of the threedimensional garage gets into a difficult position especially, in order to regain the cost, the price that can only park through improving the threedimensional garage, however, the price is high, nobody shows any interest in, the state left unused in parking stall is more and more serious, therefore form the vicious circle, smooth development of the serious threedimensional garage of hindrance. 5. Conclusion Therefore, the development of the threedimensional garage needs the country, citizens, the operater of threedimensional garage makes joint efforts. The country must make the corresponding policy, stop the street stopping putting arbitrarily arbitrarily, encourage building the threedimensional garage, adjust prices。s main form and technologica
