Design and Comparison of Three-bifurcation T-shaped Junction Interchange Scheme
Junction interchange should meet the functional needs of traffic flow conversion between expressways.Therefore,according to its traffic function in the road network,combined with traffic volume,topographic conditions,technical indicators,project scale,service level and other controlling factors,multi-scheme design should be compared and selected.Taking the design scheme of system inter-change scheme between S44 Kanglue Expressway and G8513 Pingmian Expressway in Gansu Province as an example,this paper analy-zes the advantages and disadvantages of scheme 1(T-shaped inner intersection)and scheme 2(T-shaped left turn ramp roundabout)from multiple perspectives such as project function positioning,construction necessity and traffic volume prediction,etc.It shows that scheme one has more overall advantages.
