Roundabout Properties: Arm: Crosswalk

Pedestrian crossings are often located at roundabout entry/exit points because the traffic is moving slowest here.

Expand an arm and click Crosswalk in the left hand pane. The Crosswalk page is displayed.

Use the Crosswalk checkbox to enable or disable a crossing.

The crossing page is divided into entry crossing, exit crossing and island crossing.

For each of the two lane crossing sections, the Crossing Type may be set to any of the following:

In the UK are also known respectively as:

The Offset from Entry Intersect is measured along the offside (or splitter) definition line from the intersection of that line and the inscribed circle.

The Entry Crossing Width is measured perpendicular to the angle of the crossing.

The Crossing Angle is measured relative to a line perpendicular to the offside definition line. Rotation is positive when the crossing is turned away from the roundabout. In most cases, the angle will be zero since this represents the shortest crossing distance.

You can link the entry and exit crossings by setting the Exit Crossing Type to Synchronise to Entry (Mirrored) or Synchronise to Entry (Projected). In both cases, the entry and exit crossing offsets change when you adjust the entry offset but the handling of the exit crossing angle varies slightly:

Note: In this mode, the exit fields are disabled.

The Island Crossing Type may be Projected, Bridged or Refuge.

A projected crossing has the entry and exit crossings extended until they meet.

A bridged crossing connects the entry and exit crossings at the point at which they intersect the splitter definition lines.

A crossing refuge has staggered entry and exit crossings. You can only set a crossing refuge if the entry and exit are not synchronised.

In all cases the Max and Min values represent the limiting values from the adopted design standard.
