Road incidents caused by blocked drain ans speeding traffic

Hello, could I arrange to talk to someone about the speed limit outside Tickledown, OX10 8DY? It is currently a 50, but traffic used to drive past consistently at 60-70. The speed of the traffic has increased noticeably in the last few months since reducing the speed limit in North Stoke to 20. Traffic is now driving at 70mph+. It is the site of a fatal RTA, a significant number of accidents, both a hidden dip and a blind bend, driveways exiting directly on to the road, pedestrians walking in the road, animals in the road (deer and pheasants), a damaged drain and culvert and a permanently flooded road. I would like to discuss if any of these could be addressed. I look forward to hearing from you.
