Abstract
Visualization and Analysis of Urban Taxi Demand Survey Data Track: Education Author(s): Kentaro Taguchi, Sadohara Satoru This paper analyzes taxi demand in Sendai, Japan, where there is an oversupply of taxis. As the first step for developing an urban taxi management system, taxi demand data was collected using car-mounted wireless GPS units and surveys written by drivers. Taxi demand is expressed in terms of customer population, average travel time, and purpose of travel. Taxi demand is then compared to regional data such as distances from train stations, building densities, and population densities. Taxi demand is estimated for different times of the day and days of the week using regression analysis. Supply and demand balance of the taxi market is also analyzed for different city zones.
