Abstract：Many cities are recently gearing up for developing streetcar system and many vehicle manufacturers are developing low-floor vehicles in China. This paper first introduces the researches in different types of low-floor vehicles. Then the paper elaborates the technology characteristics of low-floor streetcars in several aspects: modular design, low-floor design, vibration and noise reduction, consistency with urban roadway design, streetcar bogies with independent wheels, brake system, power supply, and safety design. Finally, the paper points out the diversity design will increase the level of difficulties in vehicle operation and maintenance. Because of that, the industry in China should quickly standardize the low-floor streetcar manufacturing process.
