GHISOLFI, V.; TAVASSZY, L.A.; CORREIA, G.H.d.A.; CHAVES, G.d.L.D.; RIBEIRO, G.M. Freight Transport Decarbonization: A Systematic Literature Review of System Dynamics Models. Sustainability 2022, 14, 3625.
Resumo: Freight transport decarbonization is currently an urgent challenge. Decarbonization strategies have a specific time to take effect, and it is essential to consider their time dependence. The system dynamics approach is well suited to represent feedback, lagged responses, and the time dependence of decarbonization strategies. We carried out a systematic literature review of system dynamics models in relation to strategies for freight decarbonization to identify the treatment of relevant dynamics of the system within the models. The 50 studies that fulfilled our search criteria were categorized by decarbonization strategies, the external factors needed to support them, and simulated policy instruments. The results show that no model presented a broad view of the system, addressing a limited combination of strategies. Most importantly, system dynamics models do not clarify how time-dependent behavior is determined, which indicates a significant research gap that can be critical for understanding the policy’s urgency and impacts.

BALTAR, Marina; RIBEIRO, Glaydston; SANTOS, Rafael. Exploratory analysis of incidents in an urban area focused on broken-down vehicles: The case of Rio de Janeiro, Transport Policy, Volume 10, Issue 1, 2022.
Resumo: This paper proposes a methodology to perform an exploratory analysis of incidents focused on broken-down vehicles using the city of Rio de Janeiro as a case study. We analysis the incidents that most impact the road traffic and try to understand the causes of these occurrences. The method used is based on historical data of the incident responses and on traffic flows. Our database was provided by the Traffic Engineering Company of Rio de Janeiro which has more than 204,000 incidents occurred between 2015 and 2017. Using statistical tools, the profile of the most frequent incidents is analyzed and policies are discussed to reduce its number and the response time.
