NSW Ambulance has reminded drivers and pedestrians to be mindful of each other while out socialising after hours to avoid collision and injury.

A review of responses for the eight months to April in the Sydney Metropolitan Region (8pm to 5am) show paramedics attended at least 189 collisions between pedestrians and vehicles. Included in the figures were people who had been hit by taxis or had fallen out of taxis.

NSW Ambulance Inspector James Porter said while not all these cases could be linked to drugs and/or alcohol they often a factor.

"More and more people are jaywalking and more and more people are taking risks," he said.

Inspector Porter said another concern was the increasing number of people who were walking while they talked or texted on their mobile phones.
