Network analysis

Use Aino to analyze street networks and identify strategic locations (for example, top crossroads for a new business) using OSM street graphs and network-analysis algorithms.

When to use

• To find the busiest or most connected intersections (based on graph centrality, connectivity or assumed pedestrian flow).

• To calculate catchment areas based on network distance.

• To rank crossroads by a simple accessibility metric (pedestrian friendliness, connectivity, walkscore-like proxy).

Steps to run a network analysis

1. Select area of interest — draw a polygon manually or select one of the pre-defined small-city areas (up to 25 km²).

1. Run the network analysis using a prompt. Example prompts:

Perform a network analysis in Area_51 and identify the top 5 crossroads for locating a new business based on assumed pedestrian throughput.

Perform a network centrality analysis in polygon "Downtown" and return the top 10 intersections by betweenness centrality.

1. What Aino does (technical outline)

• Extracts the OSM street graph for the selected area and builds a routable network (nodes and edges).

• Computes edge weights according to the selected mode (pedestrian, bicycle, car). Weights can be distance, estimated travel time, or custom scores that reflect pedestrian-friendliness (e.g., presence of sidewalks, speed limit proxies).

• Runs routing or graph algorithms (shortest paths, betweenness centrality, degree centrality, driving distance) using server-side spatial libraries.
