　　托福写作素材模板：智慧城市的兴起

　　素材段落

　　With the widespread application of sophisticated information and communication technologies, the concept of creating a ‘smart city’ has been proposed as the ultimate goal that large cities would seek in their future development. A ‘smart city’ could largely improve the quality of life and the performance of urban services. For example, it has brought local residents a more efficacious and user-friendly public transportation system. In Barcelona, a new bus network has been designed to utilize vertical, horizontal and diagonal routes with a number of interchanges, based on the analysis of the most common traffic flows. Also, when smart traffic lights are set up and traffic management software is installed, the number of green lights on each street has been optimized to avoid traffic congestion as well as to allow ambulances to reach incidents without any delay.
