In case you hadn't noticed, Chengdu's transportation system has been suffering from some growing pains recently.
Chengdu's public transportation department says that while the core areas of the city within the so-called 2.5-ring road demarcation are already relatively well serviced, the areas outside that demarcation need optimization.
From the end of this year through the first quarter of 2012, at least 500 buses will be added to serve four outlying regions: the south Hi-Tech Zone, Longtan Industrial Park, Tianhui Town and Yingxing Garden, and the Jiaozi Flyover.
These four areas, all of which lie close to the Third Ring Road, have been identified as fast-growing residential and commercial districts where passenger demand has already surpassed public-transportation capacity. Some outlying neighborhoods are served by only one or two bus lines, making transportation difficult.
In the case of the south Hi-Tech Zone, where coverage is already high, there are still key lines missing, such as a line that connects Tianfu Dadao, Yizhou Dadao, and Jiannan Dadao with Huayang. Intervals between buses setting off from the Huayang and Shuangliu bus stations are deemed too long.
The Chengdu City Traffic and Transportation Committee and the Chengdu City Public Transportation Group welcomed input from Chengdu residents via their telephone hotline and their online portals.
Transport optimization is guided by two fundamental principles: Eliminating redundancy in bus lines (while maintaining a reasonable number of maximum transfers) and increasing rate efficiency so that buses are running at optimal capacity (defined as at least 100 passengers per line per hour).
One hundred twenty-eight bus lines, more than 7,000 public buses, and 500 stops serve a daily average of 3.7 million passengers within the 2.5 ring road.
Nonetheless, the transportation department says it will continue to optimize transit lines on small and medium-sized streets within the city's central areas.
