1. A vehicular drive assist system comprising at least one processor that is programmed to:
- perform drive assist for a vehicle traveling in each predetermined area while receiving a feedback on evaluation relating to ease of travel on a road in each of the areas, as a result of the evaluation relating to ease of travel being represented by a value in a range of values indicating a degree of ease of travel on the road in each of the areas, wherein;
a variation width of the evaluation relating to ease of travel, which is to be fed back, is restricted based on static factors of road environment for each of the areas;
the variation width is a width of the range of values within which the value representing the evaluation changes by taking into account a disturbance factor of the road;
information relating to the static factors of road environment is constituted by (i) information relating to static factors of road environment which are included in map information and (ii) information relating to static factors of road environment which are not included in map information;
the value of the evaluation relating to ease of travel is provisionally determined based on the information relating to static factors of road environment which are included in map information; and
the provisionally determined value of the evaluation is corrected based on the information relating to static factors of road environment which are not included in map information.

Abstract
A vehicular drive assist system performs drive assist for a vehicle traveling in each predetermined area while receiving a feedback on evaluation relating to ease of travel on a road in each of the areas. In the system, a management center performs evaluation of ease of travel on a road for each of the areas on the basis of information obtained from the vehicle and feeds back the evaluation result to the vehicle. In this case, a variation width of the evaluation relating to ease of travel is restricted on a basis of static factors of road environment for each of the areas.
