Need for nighttime traffic police

The other night I was on my way home to Sir Syed Road, Mohammadpur with my ailing mother after having visited her doctor at Ibn Sina Hospital, Kallyanpur. It took us more than an hour to go to the hospital, whereas it should not take more than 15 minutes. But while returning, the situation even worsened. It was after 11 pm and we were stuck in severe traffic jam as the heavy vehicles like lories and trucks were making their way into the city. In Dhaka after 11 pm, there is no traffic police in city roads to control the traffic. May I humbly request the traffic police chief to seriously consider the matter and deploy traffic police 24/7 on Dhaka roads?
