ANALISA LENGKUNG HORISONTAL JALAN PADA JALUR JALAN AJIBARANG- PRUPUK

Sari

Path of Ajibarang - Prupuk with length 35.760 km ( SK. PU No. 236 A/KPTS/1997), is traffic path with high density so that traffic trouble often happened. One of the cause is planning of geometry walke at tortous area and superelevasi road; street. Of perception result, amount of curvatures walke there is 173, with R > 200 = 58, R < 200 > 50 = 95 and R < 50 = 20, competent tortous amount there 160 curves, and which do not up to standard geometry there 13 curve. Of calculation result got that 1. Require to be performed by change of sloping and tortous radius superelevasi with R minimum 112 m of superelevasi below/under 0,1 2. Curve which do not enable to be performed by change can overcome with changing speed of high plan so that smaller superelevasi With change of planning expected joint streets of Ajibarang - Prupuk growth hereinafter can serve requirement of fluency, traffic current freshment and security relateed at planning of used by road;street geometry government.
