Semi-dynamic traffic assignment with residual demand for SimCenter R2D

Features

• Quasi-equilibrium traffic assignment
• Efficient routing for millions of trips using contraction hierarchy and priority-queue based Dijkstra algorithm sp
• Temporal dynamics with residual demand, with time step of a few minutes
• Compatible with road network retrieved from OSMnx

Use cases

• Calculating network traffic flow for small and large road networks (10 to 1,000,000 links) at sub-hourly time steps
• Visualizing traffic congestion dynamics throughout the day
• Assessing regional mobility and resilience with disruptions (e.g., road closure, seismic damages)

Input Data

• Road Network
  • nodes.csv
  • edges.csv
  • closed_edges.csv (designed for disruptive events)
• Demand
• OD.csv

Output Data

• Travel time
• Travel route
