there is a lot of traffic in the east road section when
measures are not taken against road disruptions. On
the other hand, there is a lot of traffic in the eastern
road sections in without case. In Fig. 10, the leading
road network between the northern and the southern
part of the city is cut off by inundation. Hence, the
traffic volume of the network in the eastern part of
the city has been increased.
Additionally, the traffic volume of eastern
road sections is about 24,400 vehicles in "with" case.
In "without" case, the traffic volume on the same

section has decreased about 1,600 vehicles. This

Thus, it was found that implementing the

volume, it could be clarified the road section, which
has high traffic volume and is vulnerable to
inundation. Therefore, it is possible to implement
measures preferentially.

4. Results
4.1 Simulation
We simulated the scenario of the baseline
and the scenario of implement adaptation measure as
follows. For minimizing the effects of floods, the
adaptation measures are proposed in the existing
studies which are classified into hard and soft (e.g.,
Stamos et al. (2015), Madan, et al. (2015)). From Fig. 10 Result of simulation (without case)
these existing studies, we selected the elevated
arterial road for alleviating the flood damages on the
road network. The reason for choosing this measure
is that The Elevated arterial road was implemented
the eastern belt highway (National Highway No. 9)
in the Bangkok metropolitan area after an urban
flood in 2011 for alleviating effects on the transport
