Researchers say their examine findings point out a necessity for contemplating security, not simply effectivity, in GPS route-finding.


A brand new examine from Texas A&M researchers finds that taking a route with an 8% discount in journey time might improve the danger of being in a crash by 23%, stories Texas A&M At present.

The researchers in contrast routes between 5 metropolitan areas and located navigation techniques typically information drivers to take paths that carry a higher threat of crashes. Particularly, the staff evaluated each the most secure and shortest routes between 5 metropolitan areas in Texas — Dallas-Fort Price, Waco, Austin, Houston, and Bryan-School Station — together with greater than 29,000 highway segments.

Finally, they concluded that shortcuts is likely to be lengthy on saving time, however brief on making certain motorists’ security.

Whereas a GPS system is designed to supply probably the most environment friendly route, it would not at all times take all key elements that may result in a collision into consideration. For instance, GPS instruments do not essentially consider poor geometric designs, drainage issues, lack of lighting, and the next threat of wildlife-vehicle collisions.

Within the case of Texas A&M, the researchers gathered and mixed highway and site visitors traits, together with geometry design, variety of lanes, lane width, lighting and common every day site visitors, climate circumstances and historic crash knowledge to investigate and develop statistical fashions for predicting the danger of being concerned in crashes.

The findings revealed inconsistencies within the shortest and most secure routes. In clear climate, taking the shortest route as an alternative of the most secure between Dallas-Fort Price and Bryan-School Station will scale back the journey time by 8% — but the chance of a crash will increase to twenty%. The evaluation means that taking the longest route between Austin and Houston with an 11% improve in journey time ends in a 1% lower within the every day chance of crashes.

The researchers observe that navigation based mostly on security, reasonably than journey time, can lead to stopping crashes and selling general security on the highway community and finally save lives. The truth is, the staff has proposed a system structure for protected route-finding and highlighted the necessities for and obstacles in incorporating security in future navigation apps.
