We thank Mr Ronald Chan for his suggestions to improve traffic flow on expressways , including ramp metering. (Today ,28 Jun)
The ramp meter works much like a traffic light and uses traffic signals to control traffic entering the expressway. The system, as pointed out by Mr Chan, is used in some countries but for it to work well, it requires long slip roads entering expressways. This is to provide room to hold queuing traffic so that they do not in turn cause congestion on other roads. Given our compact road network in land scarce Singapore, most of the slip roads entering expressways are not very long.
On expressways, we manage traffic flows with Electronic Road Pricing during peak periods, so that with general traffic moving at optimal speeds, buses too will enjoy good travel experience.
We agree , however, that dedicated bus lanes is one way to enhance bus commuting experience. This is why we have stepped up the number of bus lanes around the island. Currently, there is a total of 203km of bus lanes, including 23km of full-day bus lanes.
These enhancements are part of a slew of bus priority measures aimed at improving overall reliability and speeds of buses en-route, so that commuters can experience smoother journeys and more regular waiting times. They complement the ongoing Bus Service Enhancement Programme (BSEP), where additional buses will continue to be added to serve new areas and shorten overall bus journey time to make public transport journeys more pleasant.
