Councillor Emily Kerr, who represents Oxford’s Bartlemas division, said she is “honoured” to take on the role.
She said: “As a local resident in the vibrant city of Oxford, I am proud to have great experience in walking and cycling in urban areas, and I am eager to learn more about what matters most for those travelling throughout our beautiful county and in our most rural areas.
“I’m a huge supporter of making improvements to help us all get around more easily without needing to rely on driving a car.
“I’d love people to get in touch with me to share their thoughts for the best active travel opportunities.”
Councillor Kerr’s role includes taking part in regular road safety working groups and workshops in both rural and urban areas.
She succeeds Damian Haywood in the post, which has previously been held by Councillor Dan Levy and Councillor Andrew Gant.
Councillor Gant, Oxfordshire County Council’s cabinet member for transport management, said: “I’d like to thank Damian Haywood for all the valuable work he did while in this post, and I am looking forward to working with Councillor Kerr in the future.
“Her enthusiasm, knowledge, and passion for the issues shine through and I am sure she will be holding our feet to the fire on all matters related to active travel.”
