1. A walking information provision system for providing information on walking to a pedestrian, the walking information provision system comprising:
an information acquisition unit configured to acquire at least information of a surrounding situation of the pedestrian;
a notification determination unit configured to determine, based on the at least information acquired by the information acquisition unit, whether there is information on walking to be notified to the pedestrian;
an attribute setting unit configured to, in response to the notification determination unit determining that there is the information on walking to be notified to the pedestrian, obtain an attribute of the information on walking to be notified to the pedestrian according to an urgency degree and an importance degree, wherein
the urgency degree is based on a physical time until the pedestrian encounters a risk in walking, and
the importance degree is a degree of influence brought about by a result when the pedestrian has encountered the risk in walking; and

an information notification state decision unit configured to,
based on the attribute of the information on walking to be notified to the pedestrian that has been obtained by the attribute setting unit, decide a notification state of the information on walking to be notified to the pedestrian,
decide a vibration physical characteristic of a device carried by the pedestrian, and
in response to the notification state including a repetition of a vibration ON period and a vibration OFF period, decide, according to the attribute of the information on walking, at least one of (i) an intermittent time being a sum of the one vibration ON period and the one vibration OFF period, or (ii) a duty ratio being a ratio of the one vibration ON period to the intermittent time, as the vibration physical characteristic of the device, wherein

the intermittent time is set to be shorter as the urgency degree of the attribute of the information on walking is higher, and
the duty ratio is set to be larger as the importance degree of the attribute of the information on walking is higher.
