Section2 Advanced Road Traffic Services

Although guiding blocks are usually used to help the visually-disabled to find their way, they cannot provide information equivalent to what the non-visually disabled can obtain by landmarks and signs.

The Guidance System for the Visually Disabled, which uses not only guiding blocks but also a voice guide with detailed information such as their current position, direction and route to the destination, was therefore introduced on three sections in Sendai City frequently used by the visually-disabled: sidewalk of the National Highway No. 48 in front of the Miyagi Prefectural Government Office, sidewalk in front of the Sendai City Government Office, and the Aoba-dori underground passage below the National Highway No. 4 (1997 to 1999).
