Some observations:

Has the LTA considered building flyovers and tunnels for cars and light vehicles - with height restrictions - to get faster-moving vehicles off the road more quickly?

Just as roundabout junctions are inefficient in today's traffic conditions, so too cross junctions with traffic lights can cut traffic speed by half.

Much streamlining can be done on existing roads. We find bus stops in the middle of filter lanes at a number of junctions along Bukit Timah and Dunearn roads. These clog the filter lanes and may subsequently affect the main roads.

The effectiveness of fly-overs is thereby reduced.

We also find private cars and taxis stopping in the outermost lanes in the city area to pick up or drop off passengers - for example along Cecil Street or Robinson Road.

There are openings in the fencing along Orchard Road to 'promote' jaywalking and this does not promote traffic flow.

The roads may be wide, but with such practices, traffic congestion is made worse.

Unless we provide recesses along roads and sheltered paths to lead to sheltered five-foot ways, we will see more traffic infringement despite all the zigzag yellow lines on the road.

Fines may discourage, but in the end, it is shielding pedestrians against rain or shine that will make for a more permanent solution.

We need better entrances to buildings and standardised carpark gantries to allow cars to get quickly into buildings and off the roads.

In buildings adjacent to wide roads, the carpark gantry must be made deeper into the building to allow some 'accumulator' effect and get cars off the main road.

This may require changes to building codes but will improve the traffic situation.

We should sort these more immediate issues progressively and re-evaluate more specialised tunnels and flyovers.
