To analyze the speed and reliability characteristics of trams under manual driving conditions in sections， wheel odometer data was used to calculate the characteristic indexes in acceleration， cruise， braking and intersection section， and influence mechanism of manual driving decision on each index was proposed. Multi-factor regression model and probability distribution model of section running speed are established. The results indicate that driver can not achieve full acceleration and deceleration due to the fuzzy control of manual driving； the contribution of terminal speed and braking coefficient to section running speed accounts for 57%， which is important for driving behavior optimization； the section running speed conforms to Gaussian mixture distribution（GMM） with high deviation rate to the common green wave bandwidth，resulting in low time reliability of tram lines.
