Open publisher page 0 citations

Abstract

With the theory of road network generalized capability,the influence of road construction on it was explored.Firstly,the traffic characteristics in work zones were analyzed.According to the characteristics,several key factors of work zone which affect the capacity were proposed.Then the influence was separated into two sectors.One was the impact on effective operation area of road network;the other was the impact on effective operation time.The specific calculation method of the related correction coefficients was set after that.Finally,a comparative analysis of road network capacity was taken in Wuhan Municipality's urban zone.It is found out that the capacity under the road construction reduces a lot.
