Long-term traffic regulations with the reduction of the vehicle travel space, such as regulations for update of the aging infrastructure and bus exclusive lane regulations, are widely introduced all over the world. Due to such long-term traffic regulations, drivers take the corresponding behaviors, and the corresponding behaviors as well as the capacity reduction due to the traffic regulation will have an influence on the transportation network. This paper evaluates the impact of bus exclusive lane regulation onto both drivers’ behavior and the traffic network using a transportation network analysis framework. As a result, it was confirmed that the uncertainty that drivers perceived about the road congestion was increasing immediately after the introduction of the bus exclusive lane. It was also confirmed that the network capacity after the introduction of the regulation is drastically reduced.
