This paper assesses the traditional hutong street system and siheyuan courtyard house as an urban development model in contemporary Beijing by comparing it with the practiced alternative. Official government standards are used as criteria for measuring the performance of the urban form types. Criteria derived from government documents emphasise the efficiency and low-carbon emission of the transportation system and efficiency in land use, via higher densities. Minimum site areas devoted to green space are also specified. We compared the use of land resources in a sample of 9 hutong areas with those of a sample of 22 newly built communities. We collected traffic data and interviewed residents in these areas. We also examined transportation as a user of urban land, as well as the implications for land resources if the 2002 conservation plan is fully implemented. It was found that the hutong development models underperform with regard to building density depending on form type, but achieve much higher population densities than suburban housing. Motor traffic infrastructure in contemporary development takes up 3 times as much of the development area as the hutong do in their development area. The hutong outperform the rest of the urban fabric with regard to sustainable transport with 0.17 of the car mode proportion for all of Beijing. There is heavy dependency on three-wheeled vehicles for goods transport and high levels of walking. Moving the remaining population of the hutong as planned would require about 1800 ha of new residential land more than 30 km from the city centre. [ABSTRACT FROM AUTHOR]
