13% more people on 40% of the land

From Wikipedia, a comparison of the relative efficiencies of high speed rail vs freeways.  The critical information being that trains move 13% more people while requiring 40% of the land.  Now to find a cost comparison.  From Wikipedia:

Moreover, train tracks permit a far higher throughput of passengers per hour than a road the same width. A high speed rail needs just a double track railway, one track for each direction. A typical capacity is 15 trains per hour and 800 passengers per train (as for the Eurostar sets), which implies a capacity of 12,000 passengers per hour in each direction. By way of contrast, the Highway Capacity Manual gives a maximum capacity for a single lane of highway of 2,250 passenger cars per hour (excluding trucks or RVs). Assuming an average vehicle occupancy of 1.57 people,[29] a standard twin track railway has a typical capacity 13% greater than a 6-lane highway (3 lanes each way), while requiring only 40% of the land (1.0/3.0 versus 2.5/7.5 hectares per kilometer of direct/indirect land consumption). This means that typical passenger rail carries 2.83 times as many passengers per hour per meter (width) as a road. Some passenger rail systems, such as the Tokaido Shinkansen line in Japan, have much higher ratios (with as many as 20,000 passengers per hour per direction). Congested roadways tend to be commuter – these carry fewer than 1.57 persons per vehicle (Washington State Department of Transportation, for instance, uses 1.2 persons per vehicle) during commute times. Congestion also causes the maximum throughput of a lane to decrease.
