The family of a cyclist killed on Cambridge's guided busway are calling for the speed limit to be lowered to avoid future acidents.

Steve Moir was killed when he was hit by a bus on the guided busway in Trumpington on September 13 and his son Liam, 19, has shared his story in a bid to change the speed limit.

Father-of-three Steve, 50, who worked at nearby Cambridge Assessment, was on his way home when he was struck by a bus at around 4.50pm.

A petition has been set up by his friend Carrie Warren, calling for the speed limit for guided buses to be reduced from 30mph to 20mph between the Railway Station and Long Road railway bridge.

Liam Moir is calling for a lower speed limit on the guided busway

In the description, she says: "We believe this step is necessary to make the section of the busway safer for pedestrians and cyclists who are in close proximity to buses with no safety markings, fence or other protection from the fast-moving vehicles.

"If the speed is reduced then the drivers have a chance of reacting to people or other obstacles in the busway in time, which may avoid or reduce the severity of any injuries."

Liam, who lives at home with his mum Elaine and two brothers, Callum, 22 and Owen, 17, wants people to understand just how important this change would be to his family.

Steve Moir sadly died in the crash on the busway

"Someone my dad knew set up the page and me and my family have just been getting behind it and raising awareness for the cause," he said.

"The petition means a lot to me and my family as buses fly down the busway and it’s very dangerous for people walking and cycling along there.

"My whole family wants to raise awareness because we don't want anything as horrible as what happened to us, to happen to anyone else.

"It's amazing to see how many people share the same views as us. I didn't realise it was going to do this well and get that many people signing and sharing it, it's amazing.

The petition is to reduce the speed on the guided busway

"It shows that after what's happened, people do want to help us and make a difference.

"Me and my dad were really close and shared a love of football and he took me to all my football matches. People should feel safe walking along the busway and maybe if the buses went slower then the bus could have stopped in time."

Steve Moir was a coach at Sawston United Football Club and Liam, who works at Premier Sport, has followed in his dad's footsteps, coaching the under 10s team.

Liam doesn't want another family to go through the same thing

The petition has more than 3,200 signatures so far and if you want to get involved you can sign it here.

This is what people who have signed the petition have said

"A family, a community and a city was changed forever in a moment with the tragic death of Steve Moir on the busway. He was a champion to his friends, colleagues, acquaintances and to the many young people he mentored. To his family he was everything. Slow things down at this point on the busway is the least that should happen. Ideally an entirely separate safe bicycle/walking route needs to be made. I am fearful of my kids cycling down it and am aware that there have been many other worrying situations that have occurred on this stretch at times where pedestrians, cyclists, buggies and buses are in such close proximity."

"I fear for my safety cycling down this path. Since the tragic death of a colleague I no longer cycle home this way as I am too scared to be that close to the buses."

"I use this path by foot everyday, the buses go so fast it's scary. It's terrible that someone had to lose their life for something to be done about it."

" Such a tragic waste of a young life, a family man, a community man. Always kind and calm and a pleasure to be around. It's a shame such a tragedy, as this, has given us cause to re-evaluate. I hope no one else has to go through what this family have been through."

In June a pedestrian was struck by a bus wing mirror as he stood close to the busway.

Cambridgeshire County Council and Cambridgeshire Police were unable to comment on the petition as the incident is under investigation.
