In the end I expect that any technically feasible improvement to the cell phone position accuracy is miniscule to the actual effort and expenditures it requires. I don't have any studies, per se, but we get enough "the house next to XXXXX Any Street" calls as it is that the "technically feasible improvement" is an improvement. In San Antonio, people "give directions" by intersections, and leave it up to the recipient to actually figure out where the destination is. "281 and Bitters" represents a ~10 square mile area to most locals, and similar scenarios pop up all over. I-10 runs "east and west" from El Paso to Houston through downtown. I-35 runs "north and south" from Dallas to Laredo. Loop 410 is a 54-mile loop around the city. Loop 1604 is a 110-mile loop around the city. Getting cell phone calls from a tourist (of which we have plenty) reporting a wreck at I-10&410 narrows it down, but still leaves ~27 miles of inaccuracy. Add in 4-8 exit ramps, 10 square miles of surrounding area, and a language barrier, and you end up with some combination of delayed response, parallel response to each possibility, and increased risk to rescuers and innocent citizens. So yeah, I'd like better locations whenever possible. pt
