Minimum transition length to merge from three lanes to two lanes dual carriageway
Minimum transition length to merge from three lanes to two lanes dual carriageway
(OP)
Am designing a three lane dual carriage road (two lanes for private cars one lane for Buses only on each side). At a certain point along the road where the traffic is low we are merging the three lanes to two lanes. What is the recommended transition length required to merge? I will also appreciate if I get a reference standard. The design speed is 60km/hr and lane width is 3.5m.
Thanks
Thanks
