Answer
The important factors are :
(ii) The rate at which the vehicles arrive in the four different roads, because using this we can alter the amount of waiting time on each of the four different roads.
(iii) The proportion of slow-moving vehicles like cycles and rickshaws and fast moving vehicles like cars and motorcycles.
Here, price of petrol is not an important factor as it has nothing to do with the waiting time of vehicles at the traffic junction.
