An article from the Chicago Sun-Times, republished on Airport Business, says that an Airport Surface Detection Equipment-X (ASDE-X) system may be installed by 2010 at Chicago's Midway Airport. ASDE-X systems are radars aimed at preventing runway incursions "by immediately notifying pilots and air traffic controllers of potential collisions with other aircraft and vehicles on runways and taxiways."In 2006, there was one runway incursion at Midway, compared to 10 at Chicago's O'Hare Airport. It was announced earlier that the ASDE-X system will be installed at O'Hare this summer.
In addition to ASDE-X, Midway will get arrestor beds -- crushable concrete at the ends of four runways to slow planes that overshoot their landings -- installed later this year.
