Traffic Study of Interchange at Noida Toll Road & Ring Road

Duration:: June 2004 to October 2004
Central Road Research Institute, New Delhi (R, I)

Findings/ Conclusions
As an endeavor to unburden the traffic load from NH- 2 (Mathura road) as well as to increase the capacity of Mathura Road Corridor, the Public Works Department (PWD), Govt. of National Capital Territory Delhi is constructing a new link along the River Yamuna from Kalindi Kunj to Ring Road and DND flyway intersection. This conversion of the existing 3 arm interchange into 4 arm interchange requires geometric design modifications. This study was taken to assess the change in travel pattern in the base year i.e., 2004 and also the horizon year i.e., 2011 due to this new link and also to critically examine the feasible layout of the interchange with 4 arms, since different plans were suggested by PWD (NCTD) and NTBCL, and also to advise Govt. of Delhi to take appropriate decision.

(i) The present total traffic handled by the intersection was observed to be 1, 44,587 vehicles per day. The total number of      vehicles approaching the intersection from Ashram, Sarai kale Khan, and NOIDA side are 67,235, 50, 813, and 26,534      respectively.
(ii) The overall traffic composition at the intersection is 48 % cars, 32% two wheelers and 8% three wheelers.
(iii) The two usual peaks were observed for the total traffic at the intersection, with a morning daily peak comprised of 9.5%       of the total daily traffic between 9-10 hrs. and evening daily peak with7.5% of the total daily traffic between 18-19 hrs.
(iv) The direction wise percentages of morning peak and evening peak traffic to the total daily traffic as observed at the       intersection were calculated and used to estimate the morning and evening peak hour traffic on different arms in the base       year ( 2004) as well as the horizon year (2011).
(v) The origin destination survey formed the basis of preparing the O-D matrix of the flows through the interchange when the       proposed connection of the Kalindi bye pass is realized. Thus, the turning movements from all the four arms were        estimated.
(vi) For the purpose of evaluation of the two alternative design layouts, the maximum peak hour flows were considered.

The critical flows of traffic on each of the element of PWD design and NTBCL design were determined by comparing the morning and evening peak flows.

The analysis of traffic flows expected in the future provides adequate ground to evaluate the performance or adequacy of the proposed designs of NTBCL and PWD, NCT Delhi. A critical evaluation suggested that the design proposed by PWD, NCT Delhi is better than the design proposed by NTBCL. In the proposal of PWD, no immediate expansion of structure is needed, physically easy for construction, least disruption to traffic, and presently widening of carriageway is not required.
