Transport Department says tolls should remain flexible because queues amid some peak periods still spill onto connecting roads, non-tunnel lanes
“Total traffic volume across the three harbour crossings has already exceeded the peak level recorded before the implementation of time-varying tolls,” the paper said.
It also said that while overall peak-hour conditions remained better than before the scheme was introduced, congestion at certain times continued to affect connecting routes and non-cross-harbour traffic.
“Adjustments to the time-varying toll structure may therefore be required in the future to respond to changing times,” it added.
The department also warned that the behavioural impact of the initial toll levels would gradually diminish amid economic growth and inflation, reducing their effectiveness in managing traffic.
