Francis S. Marte, 29, of New Brunswick was pronounced dead at the scene of the crash in Middlesex County, according to Trooper Charles Marchan.
At 3:07 a.m., Marte had been involved in a two-car collision before exiting his vehicle, Marchan said.
Marte's vehicle had rear-ended another vehicle in the northbound lanes at mile-marker 84.1 in Edison, Marchan said.
After Marte exited his vehicle on the lefthand shoulder of the NJ Turnpike, he tried to cross the northbound lanes and was struck by a Chrysler Voyager, Marchan said.
The driver of the Voyager minivan, 45, of Maryland, was not ticketed.
No other people were hurt in the separate crashes, Marchan said.
The fatal crash remains under investigation.
Several lanes of the turnpike were closed during the investigation.
