DATA ON AVERAGE SPEED OF VEHICLES ON EXPRESSWAYS DURING PEAK HOURS FROM 2019 TO 2023

I reached out to the Minister for Transport for annual data from 2019 to 2023 on three key aspects of Singapore’s expressways: the average speed of vehicles during peak hours, comparative congestion levels across different expressways, and identification of the three most accident-prone expressways. This information is crucial for understanding traffic flow and considering appropriate safety measures for our roads. My parliamentary question and Minister Chee’s response are set out below.

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.

Mr Chee Hong Tat: 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.
