* The travel website TripAdvisor has introduced a new review feature to provide travellers with access to safety information about the businesses it promotes, the company has announced. TripAdvisor, which has 456m visitors a month, allows users to search for accommodation and other hospitality sites, which are ranked by user reviews. The first feature the company is introducing is a new ‘traveller safety review’ filter. The feature will allow people to search reviews that contain reports of safety-related incidents at hotels and businesses, and will be available in all 28 languages in which TripAdvisor is available.
