(Continuation from yesterday)

Firstly, I traced routes of transportation from the home to an examination school with a highlighter. After I decided a main route temporally, I tried to simulate some accidents resulting in injury or death, on the map.

I discarded the case of more than two accident simultaneously because of the low probability. I could not make a strategy.

The problem was a time lag from the accident to giving me the precise information. If I missed an initial action, I could not expect the arrival on time by the alternative route.

However, empirically, I know that railroad companies cannot give us a precise report just after the accident, and they cannot open an alternative route immediately.

Though Twitter is good as a real-time information resource, it was not useful in this case because of the time of early morning. Youngers didn't use the smartphone in that time.

"No use. It is difficult for me to judge the whole situation, riding on trains"

I thought that I had to grape the whole situation from the outside as a third person.

In addition, even if I could observe the situation from the outside, I had to use a car in order to escape from the accident.

Generally speaking, the answer was using a taxi. But many examiner and the guardians came to pour to taxi stop. To begin with, the case became to worse, because I could not predict the time of both the departure and arrival.

"How about my private car?"

Secondly, I traced routes of main roads from the home to the examination school with a highlighter.

However, thinking about accidents and traffic jams, it became to be worse than using trains. Because there were no alternative way against the accidents, like flat tire.

I was troubled for two days.

Finally, I could reach a conclusion, while scowling at the map, opened on a floor.

"I will make a dual system"
