Bus lanes are useful only if they are fully utilised and move more passengers on the buses to their destinations faster in a jam.
However, i notice there are bus lanes which remain empty during peak hours when the adjacent lanes are jammed with cars queueing for more than 1km daily!!
Example: during evening peak hour along Teloh Blangah Rd under the viaduct towards VivoCity from Alexandra Rd junction all the way to VivoCity. Most of the time the buslane is empty except for a few buses. The >1km car queue affect many drivers + their passengers while the few buses which use the empty bus lane only benefit bus passengers who are out-numbered by the drivers / car-passengers.
Our road system should be utilised to benefit the larger group, in this case (ie for this stretch of the road mentioned), the drivers / car-passengers. (Not counting the passengers in the vans / lorries who are also trapped in the jam.)
Have you noticed other such situation else where?
