NSE NIFTY trading volume includes intraday?

NSE provides historical data for NIFTY. This includes daily turnover data. Does this daily turnover data include intraday volume, or does it only include the delivery based trade volume?

Trading volume is the number of shares that were traded during a particular period of time. It doesn’t matter whether the trade was squared off intraday or carried forward. Similar to this turnover is “the total value” of shares traded during a particular period of time and obviously it doesn’t matter whether the trade was intraday or positional.
I hope it solves your confusion.

Yes.
