Query: Speed trajectory planning at signalized intersections using sequential
  convex optimization   An algorithm is developed to optimize vehicle speed trajectory over multiple
signalized intersections with known traffic signal information to minimize fuel
consumption and travel time, and to meet ride comfort requirements using
sequential convex optimization method. A comparison between the proposed method
and dynamic programming is carried out to verify its optimality. In addition,
vehicle motion during turning is studied because of its significant effect on
fuel consumption and travel time.
