The real-time traffic information of Journey Time Indication System can be obtained from the Road Traffic Information on the Transport Department's Homepage.

The Journey Time Indication System on Hong Kong Island was commissioned in 2003 and expanded to Kowloon in 2010 to provide the estimated journey time to exit of respective tunnels from Hong Kong Island to Kowloon and vice versa. The journey time indicators provide the journey time information of different cross harbour routes and assist motorists to make an informed route choice to cross the harbour before arriving at the critical diversion points.

The displayed digits on the journey time indicators are shown in three colours for different traffic conditions: Red represents congested traffic, Amber represents slow traffic and Green represents smooth traffic. The JTIS operates on a 24-hour basis and the displayed times are refreshed every two minutes. 

There are 10 sets of journey time indicators installed at:
