    BBC Midlands Today

    Residents and business owners in Kings Heath, Birmingham, will get their first chance today to react to plans to extend a controversial traffic calming scheme.

    Parts of the area were made a Low Traffic Neighbourhood, funded by money from central government, which prevents cars going through the filters on nine local roads.

    And a pedestrianised area has been created on York Road.

    But some residents said it had turned to annoyance.
