However, the numbers of accident casualties during the period has increased, the minister informed the Legislative Council.
He was replying to a query by Congress MLC Sanjay Dutt on safety on Mumbai-Pune Expressway.
Patil conceded that the expressway is of international standards, but safety measures are not up to the international standard.
The government has taken several steps in order to improve safety measures, Patil said.
As several members wanted to ask questions, House chairman Shivajirao Deshmukh said the issue was a serious one and there would be an hour-long debate on it tomorrow.
