Traffic exiting from Doncaster North Services

As previously reported. I often use the Doncaster North Services, on entering the roundabout from the services to take the M180 lane the traffic lights do not allow sufficient time to enter the roundabout in a safe manner. Traffic exiting the services has around 6 seconds to emerge onto the roundabout before another wave of traffic approaches from traffic lights controlling M180 / M18 traffic. this 6 second gap only allows at best I lorry or 2 cars to enter the roundabout. It is obvious from the amount of debris littered on the verges of the roundabout that there has been multi accidents in that area. I do believe that this dangerous time gap needs addressing before a major accident happens.
