Traffic network planning method capable of decreasing ineffective traffic

The invention provides a traffic network planning method capable of decreasing ineffective traffic. The method comprises steps of determining traffic network nodes in a planned area; acquiring the weight allocation of different traffic modes according to acquired traffic demand information; and planning a traffic mode among the traffic network nodes in the planned area according to the weight allocation. The traffic network planning method capable of decreasing ineffective traffic plans the traffic network in virtue of seamless connection, comprehensively considers different traffic modes according to traffic demands with the purpose of a decrease in ineffective traffic, keeps the number of transfer times and walking distance to a minimum, increases transport efficiency, greatly decreases ineffective traffic, achieves seamless connection of passengers and freights among different transport modes, shortens operation time, coordinates various transport modes, prevents the independent and dispersive disadvantage of a conventional transport mode, plans a road network scheme with multiple objectives, and really optimizes the planning scheme.
