as steps, which also helps older people, parents with baby carriages, and travellers. Universal design aims to obviate such symbols by creating products and facilities that are accessible to nearly all users from the start. The wheelchair symbol is "International" and therefore not accompanied by Braille in any particular language. Specific uses of the ISA include: Marking a parking space reserved for vehicles used by people with disabilities/blue badge holders Marking a vehicle used by a person with a disability, often for permission to use a space Marking a public lavatory with facilities designed for wheelchair users Indicating a button to activate an automatic door Indicating an accessible transit station or vehicle Indicating a transit route that uses accessible vehicles The ISA is assigned the Unicode code point , showing as ♿︎ A compatible font such as DejaVu Sans must be installed to view the character. Building codes such as the California Building Code, require "a white figure on a blue background. The blue shall be equal to Color No. 15090 in Federal Standard 595B." Modified ISA Some disability activists are advocating for a modified access symbol. Sara Hendren and Brian Glenney co-founded the Accessible Icon project, designing the new icon to display an active, engaged image with focus on the person with disability. Some disability organizations such as Enabling Unit in India are promoting it, This version of the symbol is officially used in the U.S. states of New York and Connecticut. The Modified ISA is in the permanent collection of Museum of Modern Art. According to Emma Teitel of the Toronto Star, critics say that the modified image would still socially stigmatize those who have a disability but do not use a wheelchair. In May 2015, the Federal Highway Administration rejected the new design for use on road signs in the United States, citing the fact that it has not been adopted or endorsed by the U.S. Access Board, the agency responsible for developing the federal criteria for accessible design. The International Organization for Standardization, which established the regular use of the original symbol under ISO 7001, has also rejected the design.
