Analysis on Characteristic Indexes and Classification of Residential Districts Based on 30minute Accessible Commute Range

Abstract:

Based on the commute survey data of 15 residential districts, this paper determined a reasonable budget value of single commute travel time was 30 minutes. Then 30minute accessible commute range of respectively using car, railway and bus based on secondarydeveloped electronic map API(application programming interface) and geographic information system(GIS) technology was depicted. From the traffic system configuration in 30minute accessible commute range, the reason for the difference of accessible commute range was analyzed. Correlation among density of various facilities providing working post, the proportion of respondent workplace and the ratio of using car for commute in 30minute accessible commute range was specially analyzed. Finally, traffic improvement strategy of classified residential districts was proposed.
