The complexity of traffic flow phenomena on curved road with slope is investigated and a new lattice model is presented with the addition of driver’s anticipation effect for two lane system. The condition under which the free flow turns into the jammed one, is obtained theoretically by using stability analysis. The results obtained through linear analysis indicates that the stable region increases (decreases) corresponding to uphill (downhill) case due to increasing slope angle for fixed anticipation parameter. It is found that when the vehicular density becomes higher than a critical value, traffic jam appears in the form of kink antikink density waves. Analytically, the kink antikink density waves are described by the solution of mKdV equation obtained from non linear analysis. In addition, the theoretical results has been verified through numerical simulation, which confirm that the slope on a curved highway significantly influence the traffic dynamics and traffic jam can be suppressed efficiently by considering the anticipation parameter in a two lane lattice model when lane changing is allowed. •A lattice model for curved road with slope in a two lane system is proposed.•The effect of slope on traffic flow in curved road is examined by stability analysis.•Jamming transitions are analyzed through MKdV equation.•The effect of slope on traffic dynamics is investigated via simulation.
