A new paper by Michael Benedict Virtucio, Bingyu Zhao, Masahiko Iwama, and Kenichi Soga, titled “Quantifying inter-agency coordination impacts on highway network recovery after disruptions,” has been published in Transportation Research Part D: Transport and Environment.
The study investigates how different levels of coordination between infrastructure operators affect the recovery of large-scale highway networks after earthquakes. Using Tokyo as a case study, the authors develop a semi-dynamic agent-based traffic model and evaluate recovery under different coordination levels and recovery strategies. The work shows that stronger inter-agency coordination can accelerate recovery and reduce congestion spillovers.
The findings emphasize the importance of institutional collaboration in post-disaster transportation resilience, particularly for large urban regions where highway systems are managed by multiple agencies.
