Kinglong BRT bus for Xiamen city
Nowadays, BRT has been in batch use in Beijing, Hangzhou, Xiamen, Kunming and other nine cities. Most BRT models used in Beijing are 18-meter-long bus named Giant, the capacity of which is high and can speed up to 30 kilometers, but the cost is three times of an ordinary bus. While in other cities like Xiamen, Hangzhou and Kunming, most BRT buses choose 12 meters due to the cost and operation conditions.
"Compared to 18 meters BRT, 12-meter bus can accommodate more than an ordinary passenger bus and also greatly ease the pressure on public transport." , the market researcher Mr. Ding from Xiamen Kinglong said, "But the price of 12 meters BRT bus is much cheaper. The market price of 12 meters bus is only around 500,000 Yuan, while 18 meters more than one million. Moreover, 12 meters bus will be more stable, which is essential to the rapid transit system. In addition, although the capacity of 12 meters is lower than 18 meters, its flexibility and non-spatial characteristics of off-road can also greatly ease traffic pressure after increasing the number of flights in peak times."
