Most HDB multi-storey carparks (MSCPs) are designed with vehicular ramps sited next to each other, as it allows optimum use of our limited land space ("Take steps to tackle gridlock in multi-storey carparks" by Mr Louis Peh; July 31).

An MSCP with spiral vehicular ramps on opposite ends of the carpark, or with dual traffic lanes, will need more land space, which could be put to better use for greenery and precinct facilities that residents can enjoy.

For the three carparks mentioned by Mr Peh, there is high demand for short-term parking, as they are located near HDB town/ neighbourhood centres and malls.

While there are sufficient parking spaces to meet the needs of motorists, we have observed that many motorists often choose to wait for an available parking space at the lower deck, instead of moving to upper decks where there are ample parking spaces.

This practice obstructs traffic flow and causes congestion within the MSCPs.

To alleviate the situation, we have deployed our service providers to regulate the traffic flow on site during peak periods.

We also seek motorists' cooperation to move on to the upper decks, when the lower decks are full. Their consideration will help to ease the congestion in these popular carparks.
