Empirical Capacity Modelling of Roundabouts for Mid-Sized Cities

plays an essential role in terms of its ability to deal with the present traffic scenario. The changing geometrics of roundabout cause Measurement of Performance of existing roundabout vast variation in the entry capacity of the roundabout. A of weaving section, Width of non-, length of weaving, weaving section, section, Width and traffic characteristics. was very precise of approach way study was conducted to gather data from roundabouts with varying geometric parameters which are Central, Entry width, width found to be significant relationship Five geometric parameter with c island diameter capacity but Width of approach way does not fit So using empirical analysis based on five geometric to be significant for figuring the capacity. Every parameter used in this equation has a multiplicative relation with the parameter a model was developed which appropriate for Indian traffic scenario authenticated entry flow
