概要	Transit-oriented development (TOD) analysis evaluates how well the land around public-transport stations supports compact, mixed-use, walkable development that feeds and is fed by transit. Its analytical backbone is Luca Bertolini's 1999 node–place model, which scores every station area on two axes — its value as a transport node and its value as a place of activity — and diagnoses whether the two are in balance. Combined with the classic density, diversity, and design dimensions and with network measures of access to stations, the approach identifies which station areas are under-developed, over-stressed, or ripe for intensification.	Accessibility analysis measures how easily opportunities — jobs, shops, clinics, parks — can be reached from a given location, combining the attractiveness (size) of destinations with the cost of travelling to them. The gravity-based formulation introduced by Walter Hansen in 1959 sums the opportunities at all destinations, each discounted by a distance-decay function of travel cost, producing a single accessibility score per origin that has become a foundational concept in transport geography and urban planning.
