form based on distance domain is designed and the mapping relationship between vehicle speed and road slope is

established. Then the approximate dynamic programming algorithm with asynchronous parallel network is adopted

to rapidly calculate the economic cruising speed with concurrent considerations of safety and traffic efficiency. Final‐⁃
