6.9. Intersections in shared streets

Neither pedestrians nor vehicles experience any changes in ground level during the
passage of the crossing.

It is considered an accessible intersection when:

1. Pedestrians can cross the street at any designated crossing point.

2. If a tramline crosses a shared street, it shall not create any unevenness or
irregularity in the crossing, except for the longitudinal opening of railway rails, which
should be the minimum that is allowed by the transport system. At the crossing,
there shall be a clear reflectance contrast of at least 50 LRV points between the
railway tracks and the rest of the pavement 300 mm wide detectable warnings shall
be located at the beginning and at the end.

6.10. Accessible pedestrian signals

In addition to the visual traffic signals, accessible pedestrian signals on the accessible
pedestrian crossing shall have three types of sound signals that fulfil the following
requirements:

1. Activation acoustic signals: it is activated by user demand by touching the area
around the traffic light button or by a mobile application that links the user’s phone
with the traffic light. It identifies the exact location of the transmitter signal and the
location of the pedestrian crossing. This signal informs the user of the activation of
the pedestrian crossing signal in the next passage cycle. It should be of short
duration, with eight tones in two rounds.

2. Pedestrian crossing signals: automatically emitted during the pedestrian crossing
cycle and maintained throughout the cycle. It has a distinctive tone, slow and
intermittent.

3. Pedestrian signals for final crossing: it matches the final flashing green light cycle
and informs of the imminent finishing crossing time. It has a distinctive tone, fast and
intermittent.

4. The sound shall be set to ensure the crossing time of the traffic light cycle, taking
into account a maximum pedestrians’ speed of 0,6 m/s. If this requirement cannot be
fulfilled, it is mandatory to provide intermediate islands. These islands shall have
traffic lights with their own systems of visual and acoustic signals.
