It is difficult to rank these elements in importance or to say which ones, if any, are not needed. However, in combination, these components produce success. A city with great prospects for the future can have its hope shattered by a water shortage. There must be a fully equipped international airport offering flights to major global cities. There must be transport routes that effectively link the city to its hinterland.
Circumferential highways are the preferred system.
In order to attract major world events there must be an enclosed stadium offering comfortable seating in any weather. There must be a center of excellence in several fields of technology. This technology hub must bring together top scientists from academic, government, and private organizations. The city must be wired to accommodate the mushrooming global flow of voice and data communications. There must be an efficient rapid-transit system to serve all elements of the population.
