| Popis: | 104 Taipei City public bike system, YouBike, was founded in 2009. It was free of charge for the first 30 minutes, and started to charge NT$5 since April, 2015. This research used data of 3,315,691 trips in March and June, 2015, to analyze trip characteristics before and after the fare adjustment. The original data include origins, destinations, and duration of individual trips. We further expended such data as travel cost, distance, speed, and socio-economic attributes around the bike stations. By using descriptive statistics and data mining, we find（1）Trips dropped about 43% on weekends, 14% on weekdays, and 26% on average after the fare adjustment. The peak periods on weekdays occurred in the morning and evening commuting hours. （2）The turnover rate decreased from 9.6 to 7.3 times per day per bike; this improved bike availability during the peak periods. （3）No significant differences were found regarding riding-time, distance and speed. Most trips were within 2 kilometers and over 70% trips were in 30 minutes. The average speed was 6.3 kilometers per hour. （4）The average travel cost was upgraded from NT$3.3 to NT$9.1. （5）The price elasticity on weekends was higher than that on weekdays, and long-time trip was also higher than short-time trip. （6）About 48% of the trips had one end at the MRT stations, and most trips occurred at the MRT stations or schools. （7）Areas around 200 meters by YouBike stations had greater demand given high population and high income. This research suggests a higher rate for over 60-minute trips in peak periods to avoid bike insufficiency, and bike supply adjustment according to socio-economic attributes around stations. |
