The second phase of the odd even rule in Delhi received a thoroughly lukewarm response from the city's residents. The two week-long second outing of the odd even rule in Delhi came into effect on 15 April, 2016 and ended on 30 April. However, this time the traffic situation seemed to have only worsened. A Delhi government panel's report stated that the traffic crawled during the second phase of the traffic rationing scheme because of lakhs of private and CNG vehicles that were not present during the first phase.
The report further claims that in addition to these vehicles plying on the city's roads, functioning schools also supplemented the traffic woes. The report asserts that the Delhi Odd Even Rule was "largely successful" since car owners voluntarily complied, and goes on to pinpoint to nine additional factors that resulted in the congestion.
The report presented to Gopal Rai, Delhi Transport Minister, stated, "There was an additional volume of 3,88,886 cars (including private cars, car pooling and around 30,000 additional CNG additional vehicles), 1,34,598 two-wheelers and 8,000 buses, which was not there during the first phase." The committee headed by Special Commissioner Transport K K Dahiya identified major construction activities, ongoing dismantling of the BRT corridor, and negligible reduction of traffic entering from Noida and Gurgaon as key factors behind clogged roads between April 15-30.
Based on a sample survey carried out in six schools, the report said that a "very high percentage" of students used cars and other private vehicles to reach the institutes. It goes on to conclude thus a large volume of vehicles on roads in and around schools led to congestion in a radius extending up to five to six kilometres.
The report also found that the construction activity at Bhairon Marg, Rao Tula Ram Marg, and dismantling of BRT corridor acted as the major bottleneck that adversely affected the flow of traffic during the odd even rule in Delhi.
