Mr Murali Pillai asked the Minister for Transport whether the Ministry has annual data from 2019 to 2023 on (i) the average speed of vehicles on Singapore’s expressways during peak hours (ii) which expressways are significantly more congested than others and (iii) which are the three most accident-prone expressways.

Reply by Minister for Transport Chee Hong Tat:

1.     From 2019 to 2023, the average speed on Singapore’s expressways during peak hours was about 60km/h. Ayer Rajah Expressway (AYE), Central Expressway (CTE), and Pan Island Expressway (PIE) experienced heavier traffic during the peak hours. On a per lane-kilometre basis, Bukit Timah Expressway (BKE), CTE, and Seletar Expressway (SLE) had the highest traffic accident rates involving injuries or deaths.
