Calculating travel time in urban arterials with or without traffic lights is a fundamental task for all transport planners in order to adapt the system settings in all conditions. In order to have reliable and exact values, we propose the use of the variational theory (VT) applied to the Lighthill-Witham-Richards (LWR) first order traffic model and in the particular case of a triangular fundamental diagram. Research confirm that this method provides exact travel time values at the boundaries of an arterial and with the use of a minimum number of nodes and edges (Sufficient Variational Graph – SVG) and taking into account traffic signal settings. The output of the method are the accurate macroscopic fundamental diagram (MFD) and travel time distribution able to be applied for all dynamic traffic conditions.
