Abstract: To make TIA (traffic impact analysis) of logistics implants (LI) efficient,a procedure was proposed by making full use of the research achievements.Logistics volume was taken as the criterion to evaluate the necessity of TIA.The concept and calculation method of traffic impact degree,instead of traffic service level,was used for TIA to express the influences of a LI on existing traffic.Measures to decrease traffic impact were proposed,including improvement of the traffic management at crossings,careful design of the entrances and exits of a LI, and clear layout of the signs and symbols of roads.
