Traffic planning

The initial phase, traffic planning, often begins with the preparation of a transportation master plan for a municipality. That includes research and data collection to permit statistical analysis of traffic data, and the application of computer modelling.

The result is a broad master plan for the major roadway network, pedestrian and bicycle corridors, and public transportation routing.

Traffic impact assessment

We do traffic impact assessments for residential and commercial developments to establish:

• A roadway hierarchy;
• Local access requirements;
• Traffic control and signalization needs;
• Parking requirements;
• An internal circulation pattern;
• Recommended cost sharing for roadway improvements required as a result of the proposed development.

Functional planning

Functional planning is the preparation of preliminary designs based on background and projected traffic volumes. This involves:

• Planning for upgrading of existing roadways;
• Determining vertical and horizontal alignments;
• Planning roadway interchanges;
• Planning the staging of construction.

At this stage, the assessment of environmental impact and public consultation are important.

Design

We prepare detailed engineering designs for the construction of all types of urban and rural roadway infrastructure, including parking layouts, interchanges, bus terminals, highways, local roads, pedestrian crossings, and bicycle and walking paths.

We provide drawings and specifications, including details related to detouring, traffic signing and accommodation of traffic during construction. We carry out the selection of construction contractors through tendering or negotiation, and make recommendations for contract award of the various project components.

Construction

During construction, we provide construction survey layout, inspection for conformity with project requirements, management of contractor's progress payments, and record keeping of the construction process.

We provide as-constructed drawings of the work after completion, and we arrange for the necessary construction completion certification. We also coordinate final approvals of the project after the necessary maintenance period has been completed, and provide final acceptance certification.
