Meanwhile, the passenger remained standing in the unlit Isabel offramp area near the creek crossing. A second man who is currently unidentified and apparently unrelated to the Uber ride was also a pedestrian in the area, according to Hahn.
Both men ended up in the offramp lanes rather than the shoulder and were struck by a Honda Civic and then by a big-rig, according to Hahn.
The man who had been the Uber passenger died at the scene, Hahn said. His identity has not yet been revealed publicly by the Alameda County Coroner's Bureau.
The second pedestrian was transported to an area hospital in critical condition. Authorities have not yet confirmed his identity or what he was doing on the offramp. "Our big question is: Where'd that other pedestrian come from?" Hahn said.
The circumstances of the collisions remain under investigation. Neither drugs nor alcohol were suspected as factors for the Civic or big-rig drivers, according to Hahn.
Anyone who may have witnessed any aspect of the situation can contact the CHP-Dublin office at 925-828-0466.

* The city of Dublin has recently increased its efforts to inform the public of the correct electric scooter road laws.
Via brochure handouts, social media and online posts, city staff have restated the legal guidelines for e-scooter riders given their rise in popularity. City staff have said the clarification of rules was brought on by a large number of riders neglecting to follow them.
"We had become aware of some incidents throughout Dublin in which teens and pre-teens had been riding electric scooters unsafely, and often without a driver's license," said Shari Jackman, communications manager for the city.
"There had been some near-misses with electric scooters coming too close to hitting pedestrians on sidewalks or in crosswalks, or passing intersections and driveways without observing other motor vehicles," Jackman added.
In a social media post, the city listed out a set of laws specific to e-scooters operators and addressed the reasoning behind the post.
"Electric scooters have become quite popular as a mode of transportation, especially for teenagers," city officials said. "Unfortunately, many electric scooter drivers neglect to follow the proper rules of the road, which can result in accidents and injury."
Main rules for riders include wearing a helmet at all times. Scooters that are intended for one person at a time must be used by one person at a time.
"Users must carry a valid driver's license, ride at a maximum speed of 15 miles per hour (and) dismount and walk for left turns," the official release said. "Do not ride on sidewalks, abide by crosswalk regulations (and) follow all rules that apply to motor vehicles."
