Road incidents in Singapore: 3,260 alerts in ten days, and where they happened

PantauSivik has been keeping a record of road incident alerts since 17 October. We now have ten full days, from Sunday 18 to Tuesday 27 October 2026, with 3,260 alerts in them. This post looks at what kinds of incidents they were, what time of day they were logged, which roads they named, and how weekdays differ from weekends. It follows our earlier look at MRT station crowds and lightning, and uses the same kind of records.

How we counted

An alert here is one road incident notice from LTA's traffic data, such as "Vehicle Breakdown on AYE (towards Tuas) after Jurong Port Rd". We keep one record for each incident and count it once, at the time we first logged it. In the samples we checked, that was 3 to 5 minutes after the time written in the alert. The days are Singapore time, and we left out Saturday 17 October and today because they are not full days.

These are alerts, not crashes. One crash can lead to a notice about the accident and a second one about the heavy traffic behind it. LTA's feed mostly covers expressways and major roads, so quiet streets are not in it. About 84% of the alerts (2,723 of 3,260) name one of nine expressways.

What the alerts were about

• Roadworks, 1,261 (39%). The biggest group, and the one least tied to the day of the week.
• Vehicle breakdowns, 1,083 (33%). About 108 a day. Together with roadworks, they are nearly three quarters of everything.
• Accidents, 430 (13%). About 43 a day.
• Heavy traffic, 373 (11%). Far more concentrated in time than any other type.
• Other, 113 (3%). Obstacles (58), miscellaneous (39), unattended vehicles (10) and road blocks (6).

What time of day

Accidents have two peaks. The morning one is bigger: 28 alerts at 7am, 45 at 8am and 38 at 9am, which is 111 of the 430 (26%). A second, lower peak runs from 4pm to 8pm with 120 (28%). They do not stop overnight, either. There were 7 accident alerts in the hour from 1am and 7 in the hour from 4am.

Heavy traffic is the type most tied to rush hour. The hours from 7am and 8am held 128 alerts (34%) and the hours from 5pm and 6pm held 136 (36%), so those four hours account for about 71% of all heavy traffic alerts. The single busiest hour was 6pm, with 82. Between 9am and 4pm it was mostly under 15 an hour.

Breakdowns do not follow rush hour much. From 7am to 8pm, every hour had between 46 and 77 alerts, with the highest at 3pm. Overnight is much quieter, apart from the hour after midnight (32).

Roadworks have two humps. The larger is late at night: 10pm to 1am had 486 alerts, 39% of the type, with 188 in the hour from 12am alone. The other comes at 9am and 10am, with 147 and 137. We can't tell why from these records, and the time is when the notice reached us, not when the work started. But if you drive at night, expect works notices.

Day by day

Tuesday 27 October was the busiest day, with 415 alerts. It had the most heavy traffic alerts (64) of the ten days and the most accident alerts too (59). Wednesday 21 was second with 380. The quietest days were the weekend of 24 and 25 October, with 263 and 254. Sunday 25 had only 5 heavy traffic alerts all day.

Roadworks hardly moved. The daily count stayed between 100 and 154, and Sunday 25 had 130, more than Monday 26 (100).

Weekdays and weekends

We have seven weekdays and three weekend days. On a weekday we averaged 48 accident alerts and 49 heavy traffic alerts a day. On a weekend day it was 30 and 11. Heavy traffic nearly disappears at weekends, which fits it being a commuter thing. Breakdowns dropped from about 120 to 82 a day. Roadworks were slightly higher on weekends, at 130 against 124. With only ten days, treat the weekend figures as a first look, not a pattern.

Which roads

The PIE was named in 819 alerts, 25% of the total and more than twice the AYE (382). It led for breakdowns (323, 30% of all breakdowns) and accidents (105, 24% of accidents) as well as roadworks (268). The PIE is the longest of the expressways, so more alerts on it is no surprise, but it is a long way ahead even so.

• Accidents: PIE 105, SLE 56, BKE 50, TPE 37, CTE 35, AYE 31.
• Breakdowns: PIE 323, AYE 133, SLE 125, BKE 115, TPE 96, CTE 90.
• Heavy traffic: PIE 101, CTE 56, AYE 44, BKE 35, TPE 24, SLE 20.
• Roadworks: PIE 268, AYE 159, TPE 152, ECP 97, BKE 94, KJE 81.

The ECP and the KJE look different from the rest. They had many roadwork alerts (97 and 81) but very few accidents (8 and 9).

Spots that came up again and again

Some places show up many times in ten days. This table gives the ones with the most alerts of each type. The road and direction are as written in the alert.

For roadworks, a high count most likely means the same job showing up again on different days, not 28 different jobs. A count here says how often a place was in the news, not how risky it is. For accidents, no single spot had more than eight alerts, so they were spread out.

What this does not tell us

• It is ten days, and one of them, Tuesday 27 October, was the busiest of the ten. A longer record will say more about what is typical.
• We know when an alert was first logged, not when the incident cleared, so we can say nothing about how long incidents lasted.
• Alerts depend on what LTA reports. An incident that was never reported is not here, and a big one may be reported more than once.
• Busier roads will have more incidents. We have not adjusted for traffic volume or road length.

How to use this

• If you drive in the morning, the hours from 7am to 9am have the most accident and heavy traffic alerts. In the evening, plan for 5pm to 7pm.
• Check expressway travel times and traffic cameras before you set off, and the incident layer on the Map for what is on your route.
• Roadworks alerts go up late at night. If you drive then, look at the alert before you leave.
• You can get public alerts on your phone for the sectors you choose.

Common questions

How many road incidents did PantauSivik log from 18 to 27 October 2026?

3,260 alerts. Of those, 1,261 were roadworks, 1,083 vehicle breakdowns, 430 accidents and 373 heavy traffic, with 113 other alerts. This is a count of alerts, not an official count of crashes.

Which expressway had the most incidents?

The PIE was named in 819 alerts, about one in four. The AYE had 382, the TPE 317, the BKE 303 and the SLE 274. The PIE is also the longest expressway, so this does not mean it is the most dangerous per kilometre.

When do accidents happen most on Singapore expressways?

In our ten days the busiest hour for accident alerts was 8am, with 45. Late afternoon was the second peak, with 120 alerts between 4pm and 8pm. Accidents were logged at every hour of the day.

Is traffic worse on weekdays?

For accidents and heavy traffic, yes. Weekdays averaged 48 accident alerts and 49 heavy traffic alerts a day. Weekend days averaged 30 and 11. Roadwork alerts were about the same on weekdays and weekends.

Where does this data come from?

PantauSivik records the road incident alerts in LTA traffic data. Each incident is counted once, by the time we first logged it in Singapore time. It mostly covers expressways and major roads.

Sources: PantauSivik records of road incident alerts in LTA traffic data, first logged from 18 to 27 October 2026 in Singapore time. Each incident counted once. Roads are as named in the alerts. Percentages are rounded.
