The Tualatin River National Wildlife Refuge is located fifteen miles south of Portland, Oregon, a city known for its abundance of outdoor recreational opportunities and an expansive transportation network of light rail, busses, commuter rail, streetcars, and bike routes. National wildlife refuges provide opportunities for visitors to learn about and interact with the environment, which help to increase public appreciation of fish and wildlife. In order to develop strategies for increasing visitation and improving visitor experiences on the refuge, staff members are interested in examining likely sources and demographic characteristics of potential visitors. An analysis of transportation accessibility to the refuge was conducted using a multimodal transportation network dataset and custom service area and demographics tools. Access was measured in terms of travel distance and in terms of the amount of time taken to reach the Refuge by driving, riding a bus, biking, and/or walking.
