About Rehab Corridor Regions

Rehab corridor regions are used to associate rehab subassemblies to specific chainage ranges along the rehab corridor. Therefore, to assign different rehab subassemblies to sections of the corridor, you create regions.

Generally speaking, rehab and crossfall optimisation subassemblies provide an easier way to perform rehab design and analysis in your rehab corridor optimisation workflows. These subassemblies are designed to help you to determine ideal design lane slope outputs and have additional parameters that other overlay subassemblies don't.

To work with a rehab corridor region, you must first create a rehab corridor in your drawing. Next, edit the existing rehab corridor and pick an existing rehab corridor region or create a new corridor region.

BestPractice: Instead of creating one region for a long rehab corridor, dividing the corridor into multiple, smaller rehab regions typically results in faster processing time for corridor rebuilds and other functions. For example, on a 5,000 metre rehab corridor, create five rehab regions, each of which is about 1,000 metres long. This reduces the processing load when rebuilding the rehab corridor.

There are various ways you can edit rehab corridor regions. You can:

• move the region’s start or end chainages
• add baselines
  Note: You can create a rehab corridor with multiple baselines and manually assign regions to those baselines.
• set or edit subassembly frequencies
• set or edit targets
• change a region subassembly
• split a region into two regions
• merge two regions into one region
• copy rehab corridor regions
• match the parameters of one region to other regions
  Note: Lane parameters can not be copied from region to region.
• add regions
• isolate regions
• hide regions
• delete regions
