9F-1: Introduction to Traffic Mobility and Safety Mitigations

The two major categories of mitigations are:

1.   Mobility Mitigations with Safety Considerations, and

2.   Safety Mitigation with Mobility Considerations.

This section provides tables of mitigations used to address mobility and safety concerns on Traffic Critical Projects (TCP), see Section 9E-1.  These mitigations are intended to be considered early in project and concept development to facilitate minimizing the impacts that construction and maintenance operations have on mobility and safety.  Section 9F-2 contains additional guidance for the application of mitigations for different types of construction and maintenance work.

Mobility Mitigations with Safety Considerations

Mobility mitigation with safety considerations focuses on providing reliable and acceptable travel times with the goal of not adding additional delay from the base condition before traffic is impacted by construction or maintenance activities.  Table 1 presents several mobility mitigations with safety considerations.  Typically, these are included in construction contract documents.

Table 1: Mobility Mitigations with Safety Considerations.

When mobility mitigation with safety considerations is not possible or practical, consideration should be given to providing safety mitigations with mobility considerations.

Safety Mitigation with Mobility Considerations

When mobility impacts are necessary and safety concerns exist, consideration should be given to providing safety mitigation with mobility considerations.  Table 2 presents several safety mitigations with mobility considerations.  Typically, these are included in documents other than the construction contract documents.
