Despite the established fact that female travelers face more safety risks when on a business trip, corporate travel policies have been found lacking and not built with women in mind.

Women account for nearly 40 percent of business travelers based in the U.S., according to new research from the Global Business Travel Association and WWStay polling travel managers and buyers.

According to the research, while 69 percent agreed that women face greater risk than men on the road, only 18 percent of policies specifically address the safety and security of female business travelers and only 21 percent have revisited their travel program due to these concerns.

“While this research revealed travel buyers are concerned about female business traveler safety, only 18 percent of travel policies specifically address female safety,” said Christle Johnson, president of the Global Business Travel Association, in a statement. “As an industry, we need to do more to ensure the safety of our female road warriors, especially as women make up an ever-increasing amount of our business traveler population.”

Lodging is a concern when it comes to female safety on the road; 63 percent of travel managers said the location of lodging accommodations are one of the safety concerns they have, with 54 percent also concerned about the type of lodging.

The survey also found that only half of travel programs advise travelers not to stay at a particular property due to safety concerns, and only 44 percent sometimes or often reject bids during the lodging request for proposal process due to security issues.
