This work presents a theoretical analysis of tidal traffic flow that is based on the Kinematic Wave Theory (KWT). Also it provides a number of insights on the effectiveness of tidal flow lane management in terms of motorway capacity, throughput maximisation, and total time spent. The main question this work addresses is: If inflows and outflows are balanced to maintain the bi-directional traffic in a steady-state for a fixed total number of desired bi-directional trips, what is the distribution of densities that maximises the bi-directional total outflow. How the infrastructure should be managed to accommodate this distribution? For the analysis of tidal traffic flow a simple kinematic wave model is employed that is based on a generic or a triangular fundamental diagram (FD). Two location-dependent concave FDs one for each direction of traffic are employed to discuss the kinematic wave solutions of the prevailing traffic.
