Japanese aerial survey firm Pasco Corp. will soon begin selling software that shows on a computer screen the safest route home from a person’s workplace as well as the distance he will have to travel on foot when transportation service is disrupted due to a major earthquake.

The software, which covers the 23 wards of Tokyo, will also indicate the degrees of danger for various areas using different colors and point out the locations of emergency evacuation points, convenience stores, hospitals and public facilities that distribute water and offer other help.
