This terrible incident caused between 12 to 18 casualties over a few days period due to excessive heat and lack of resources while stranded, and because ambulances couldn't get to these people in time.
An even worse incident happened in Indonesia at the East Brebes Toll . This is similar to what happened in China. A large population of the country was en route to celebrate a national holiday when massive amounts of traffic caused a huge congestion that some say lasted for 35 hours.
While this traffic is always bad during the holiday season, since so many are traveling at the same time, the toll booths made it catastrophic because they weren’t capable of handling that volume of motorists all at once.
