Dunedin City Council data revealed 45 pedestrians older than 65 were injured by vehicles when crossing a Dunedin road between 2008 and 2012, Mr Shepherd said.
The injuries included 23 minor, 21 serious and a fatality, he said.
Most of the older pedestrians were struck on the near side of the road on fine weekdays between noon and 3pm.
The time of injury could be because more senior citizens were in town before the free travel on buses finished at 3pm.
Some pedestrians were getting older and slower and vehicles were getting faster, quieter and more numerous. Age Concern Canterbury research revealed that Christchurch pedestrians who were older than 60 had accounted for 60% of pedestrian deaths in the past 18 months.
The most dangerous time for a senior pedestrian in Christchurch was on Wednesdays, Fridays and Saturdays in winter, between 4pm and 8pm, on the far side of the road.
''They are probably taking a little longer to get across the road. Maybe, they are walking a little bit slower and their perception of time and distance and speed comes into play,'' Mr Shepherd said.
''The road can be clear as you start to cross ... but by the time you get to cross to the second half, a lot of time has elapsed.''
He was unsure why senior pedestrians in Dunedin were being struck on the near side of the road.
''Whether it's people ducking out between parked cars, or not looking or assuming that people will give way to them, I don't know.''
Reduce the risk
• Cross at traffic lights or zebra crossing.
• Do not cross between parked vehicles.

• Watch for turning vehicles at intersections.
• Be vigilant when crossing near a curve or hill crest.
