The Number 38 bus service threads a north-south path through Edinburgh, far from the picture postcard version of Scotland’s capital.
It serves a college, retail park and two hospitals, but the amount of time it takes to travel this route is getting longer.
Scotland’s bus industry has warned that the growing number of vehicles on the road, congestion at peak times and not enough priority measures for buses is making its services less attractive.
The average speed for a bus in Scotland is now 11.3mph, down from 14.9mph two years ago, according to industry data.
Lothian Buses’ 38 crosses eight of Edinburgh’s major roads and is one of the services worst affected by congestion in a city known for its reliable bus service.
It is the waiting at these traffic pinch points which can cause stress for shop worker – and number 38 regular – Nico Reverie.
“You can obviously see what the hold ups are, but there’s not a lot you can do about it,” he said.
“It is frustrating when there are delays as I need to make a connecting bus so you’re sometimes not sure if it is going to happen.
“I need to allow more time to get to work so I’m not late.
“It is just the traffic really, otherwise it is a decent service.”
Research commissioned by trade body CPT Scotland shows there has been a significant increase in running times of the Number 38 service over the last 20 years – with rising traffic volumes, a reduction in speed limits and cycle lanes all contributing to this.
