| Abstract: | By deriving the incomplete transition curve parallel arc length formula, the paper educed the road plane curve parallel arc length general formula and revealed the inherent contacts among straight line,transition curve and circle line, some helpful conclusions are also be given. Then the paper gived the methond of transition curve parallel coordinate calculation and area calculation between transition curve and its parallel with parallel arc length. |
