The Los Angeles Times has mapped over one-half a 1 G m pedestrian accidents inwards L.A. County inwards gild to visualize the county's nearly unsafe intersections. Walking inwards LA uses information from the California Highway Patrol to render a heatmap of the nearly unsafe intersections for pedestrians.
The heatmap highlights to a greater extent than than 800 intersections which convey a higher charge per unit of measurement of pedestrian injury or expiry than the county averages. The 817 unsafe intersections are equally good available to endure viewed inwards listing form.
Map developers volition endure interested inwards this How We Did It article on how the map was created. The article explains how the information was collected, processed too mapped. The heatmap information was added to the map tiles using TileMill, which is an economical agency to visualize a large sum of information on an interactive map.
The map uses the Leaflet.label plugin to add together labels to around of the nearly unsafe intersections. The labels are too then connected to the highlighted locations using a custom pointer, created yesteryear writing a pocket-sized extension to L.Path (the JavaScript is provided inwards the article if yous desire to re-create this idea).
The LA Times article points out that many of the nearly unsafe intersections are inwards around of the densest neighborhoods. This doesn't hateful that the map should endure normalized yesteryear the sum of pedestrian traffic. If yous wanted to cut down the divulge of pedestrian accidents equally much equally possible it would brand feel to endeavour too increase the security at the intersections which are responsible for the nearly accidents whether or non they convey the nearly human foot traffic.
However it is interesting to compare the LA Times map of the nearly unsafe intersections alongside Eric Fischer's Daily Pedestrian Extrapolation map. This map shows intersection pedestrian counts (extrapolated to daily totals). The 2 maps produce appear to demo that many of the nearly unsafe intersections inwards LA are the intersections alongside a high human foot traffic, specially inwards the Downtown area.
