Decision Support for Service Placement under Changing Transport Accessibility

My thesis investigates how to support decisions about the placement of essential services when transport accessibility changes with seasons, weather, and network configuration. It connects the locations of people and services with road and public transport networks, travel-time limits, and service capacity.
Methods and case studies
- Network-based assessment of seasonal accessibility, including rainfall-related deterioration of unpaved roads and temperature-driven reconfiguration of Arctic transport connections.
- Genetic algorithms and public transport route generation to explore service placement alongside changes to transport connectivity.
- Comparison of new services, road connections, and public transport routes in an urban redevelopment case in St. Petersburg.
Findings and further questions
The studies show that environmental conditions can redistribute flows and change which services people can reach. Improving transport connections can complement new facilities and, under the modeled conditions, reduce the number of additional facilities needed.
Building on initial heat-stress experiments, I am interested in integrating environmental variability with joint network-and-service optimization. A further hypothesis is that historically formed urban structures may set limits on the effectiveness of particular accessibility interventions.
