Article Synopsis
- Quantifying disruptions on rapid transit resilience is essential for effective transport planning.
- A composite resilience score is proposed, based on four indicators and a weighted network model that considers station structures, line capacities, and travel demand.
- Analysis of Singapore's rapid transit system shows how our method assesses future line impacts and identifies resilience tipping points under varying demand, indicating that demand redistribution can unintentionally harm resilience.
Article Synopsis
- The radiation model is a key tool for predicting human migration, focusing on location attractiveness influenced by distance and neighboring areas.
- The model traditionally uses population as a measure of attractiveness, but this approach may overlook non-economic factors, especially in developing countries.
- By extending the radiation model to include amenities, the improved model shows a 10.3% increase in prediction accuracy and suggests that amenities can effectively encapsulate the economic opportunities typically represented by population data.
A general framework for probing the dynamic evolution of spatial networks comprised of nodes applying force amongst each other is presented. Aside from the already reported magnitude of forces and elongation thresholds, we show that preservation of links in a network is also crucially dependent on how nodes are connected and how edges are directed. We demonstrate that the time it takes for the networks to reach its equilibrium network structure follows a robust power law relationship consistent with Basquin's law with an exponent that can be tuned by changing only the force directions.
