Police were called to Ongar Road just before 3pm with a number of vehicles involved.
The 48-year-old man died at the scene.
Detective Sergeant Adam High, of the Serious Collision Investigation Unit, said: “We are in the early stages of trying to establish the circumstances surrounding this tragic incident.
“We have spoken to a number of witnesses and are still looking to trace the drivers of a Citroen C4 Cactus and either a Honda Jazz or a Kia Picanto, which were in the area at the time.
“I urge them to get in touch as soon as possible. Both cars will have damage to their bodywork.
“We have been told there were drivers who were in the area at the time of the collision, and left before we arrived.
“I am keen to hear from anyone else who was in Ongar Road but has yet to speak to us, and anyone with dash cam or CCTV footage.”
Essex Police believe road will remain closed throughout today and until this evening’s rush hour so that they can complete their forensic examinations of the scene.
Anyone with information is asked to contact the Serious Collision Investigation Unit on 01245 240590 or email CollisionAppeal@essex.pnn.police.uk
