In 1920s, the result of adopting exclusive zoning ordinances by the U.S. has accelerated suburbanization and made what we call automobile dependent city, which in turn expands urban area, consumes more energy, and deteriorates air quality. Later, many planners and researchers believe that promotion of mixing land uses (part of diversity) is strongly associated with reduction of travels and helps for urban sustainability. In Taiwan, although the subject of “mixed land uses” has been studied for determining land-use compatibility, residential environmental quality, and mode used for travel, very few researches were able to look into the composition of mixing land uses. Through field surveying, interviewing and questionnaire survey of the residents in Beitou district in Taipei and Geographic Information Systems for laying out the businesses and services, this research aims to expose the underlying mixture/diversity of neighborhood activities in terms of places.
The statistical analyses based on 5 local market places and 17 neighborhoods unveil that the more the diversity of the neighborhood, the shorter the travel distance exclusive working trip. The Market Oriented Businesses or Services such as grocery stores, restaurants, bakeries, Chinese herb stores, healthy food stores, shoe’s shops, real estate agents, internet service centers, cartoon and video rental stores, kindergartens, photo shops, clinics, and post offices are close to the local market places and they are essential to resident daily life. The more the diversity of market oriented businesses or services, the more the shorter the travel trips. If planners are able to re-arrange the land use plan with the incentive and zoning ordinance support, it is very likely that the shift of promotion of cycling or pedestrian trips substituted for automobile usages will reduce energy consumption, which in turn results in urban sustainability.
