Traffic generated from residential land uses and traffic attracted to employment zones contributes the most to person kilometers of travel. The fundamental importance of the average length of commuting trips as a measure of sustainability is widely recognized by researchers. The urban consolidation, proportion wasteful and travel performance efficiency index have been defined as a performance indicator based on the relationship between the actual mean journey-to-work trip length, minimum and maximum trip length given the spatial distribution of homes and workplaces. These indexes are tested with data for Sapporo, Asahikawa, Hakodate and Kushiro in Hokkaido.
