The South East Busway in Brisbane experiences significant congestion during morning and evening peak periods. The 16.5km busway operates 55 bus services between Eight Mile Plains and Queensland Bus Station, though travel times have risen to 27 minutes due to issues like bus bunching at crowded stations. Population growth and added services have exacerbated the problem. Proposed solutions include increasing park-and-ride facilities, better timetabling using passenger data, merging with other transit modes, rerouting via Legacy Way Tunnel during peaks, and reducing dwell times at stations through announced loading zones and encouraging go card use.
