Simulation and comparison of two fusion methods for macroscopic fundamental diagram estimation [PDF]
Archives of Transport, 2019 Accurate estimation of macroscopic fundamental diagram (MFD) is the precondition of MFD’s application. At present, there are two traditional estimation methods of road network’s MFD, such as the loop detector data (LDD) estimation method and the floating

The price of anarchy in transportation networks by estimating user cost functions from actual traffic data [PDF]
, 2016 We have considered a large-scale road network in Eastern Massachusetts. Using real traffic data in the form of spatial average speeds and the flow capacity for each road segment of the network, we converted the speed data to flow data and estimated the ...

Measuring urban road network vulnerability to extreme events: An application for urban floods [PDF]
Transportation Research Part D: Transport and Environment, 2019 Designing and maintaining resilient transportation systems rely on identifying potential vulnerabilities and inefficiencies before crises occur. However, given the complexity of transportation networks, as well as the diversity of ways in which systems ...

The Baltic Journal of Road and Bridge Engineering, 2020 Deficiency or inadequate allocation of road maintenance and development funds leads to total road network degradation. In order to ensure proper condition of road pavement with a limited budget, we need road maintenance optimisation for the entire road ...
