Pedestrians accounted for 20 per cent of road deaths in WA this year and almost half of them were more than 50 years old.
Police figures show 121 people had died on WA roads by yesterday, including 24 pedestrians. Of those, 47 per cent were aged over 50 and almost 30 per cent were over 70.
"This is a Statewide problem," Assistant Commissioner Gary Budge said. "There are as many older pedestrians killed in the country as there are on the busy roads in metropolitan Perth.
"These are tragic and preventable fatalities."
Mr Budge said inattention was the main cause of older pedestrians being killed. Many simply "stepped out into the traffic".
"Their age can make them more susceptible to serious injury and more likely to succumb to these injuries," he said.
"Pedestrians were not at fault in all the incidents, but our analysis concerning those 'most at risk of becoming a casualty' is consistent with trends from previous years."
The toll included 81-year-old great-grandmother Beryl Dunn, who was hit by a car as she crossed about 50m from traffic lights on Canning Highway near Stock Road in Palmyra on August 21.
Ms Dunn was a "fit and bright" mother to five, grandmother to 15 and great-grandmother to one, and her youngest son, who did not wish to be named, said his family's thoughts went to the 18-year-old man who was driving that day.
"The real tragedy is the young bloke, he has to live with this for the rest of his life," the son said.
"Elderly people not only need to look after themselves but if they are involved in these accidents, it's hurting other people, which no old person wants to do."
Ms Dunn's son also said his family believed older people may be reluctant to cross at controlled intersections because traffic signals changed too fast for them to cross.
Major crash investigators are asking for the public's help as they piece together a crash in Henley Brook which has left a 71-year-old pedestrian in a critical condition.
The man sustained life-threatening injuries after he tried to cross West Swan Road from the westbound to the eastbound lane about 9.25pm on Saturday.
