More details have been released following the death of a 61-year-old man on the A27 at Chichester.
The accident also involved a white Ford Focus on the eastbound carriageway between the Stockbridge roundabout and the Whyke roundabout on Friday, January 20 at 5.30pm.
Sussex Police said the man died from his injuries. The driver of the car, a woman aged 42, from Bognor Regis was uninjured.
Police said they were currently looking to find the man’s next of kin.
This is the third death on this stretch of the A27 since Friday, December 2 December, 2011.
Sergeant Melanie Doyle of the roads policing unit said: “Following the first two fatal collisions Sussex Police officers visited the area and provided people who are living near to the road with high visibility jackets. We would encourage anyone walking in the area at night to wear these jackets to help prevent another tragedy.
“The area where these three deaths have taken place is very dark at night, making it very dangerous. All pedestrians should try to use the pedestrian crossings along the A27. This may add a few minutes to your journey, but it could save your life.
“Officers have been in the area talking to local residents and giving advice on how to keep safe while walking near to roads at night. Police have also been monitoring the road during the hours of darkness to ensure that drivers are complying with the speed limit.
“We have also been talking to the district council and the Highways Agency to see if there are any measures that can be put in place to prevent any further tragic deaths.”
Anyone with information about what happened should call 101 quoting Operation Anagram.
