SPATIO-TEMPORAL ASSESSMENT OF MIXED LAND-USE IMPACT ON TRAVEL DEMAND

Abstract

Urban mobility pattern studies are one of the interesting issues in GIScience which provide appropriate means for urban transportation planning and management. Mobility across the city has a direct relation with the land-use pattern. This paper investigates the spatio-temporal effect of the land-use mix at street level on urban movement. Taxi pick up and drop-off data in Manhattan was chosen as the sample data in this study. Trips are classified into two parts (weekdays and weekends trips) and then the correlation between mixed land-use and number of trips occurred in different time windows in each street segment, is calculated. Results indicate positive impact and moderate correlation between mixed land-use and number of trips. In streets with high Entropy, homogeneous distribution of the number of trips at each time window for the weekend and non-homogeneous trip distribution for employment and commercial and residential areas for weekday trips was observed. Also, in streets with low Entropy, non-homogeneous trip distribution at different time windows for both weekday and weekend were observed upon to dominant land-use.
