Traffic Separation Scheme Planner

Traffic Separation Schemes are the maritime equivalent of highway lane markings — essential structures that organize vessel movement through congested or high-risk waterways. Designing them correctly requires a precise understanding of international maritime regulations, local hydrography, vessel traffic patterns, and the practical realities of how ships of different sizes and types actually navigate. The Traffic Separation Scheme Planner helps maritime authorities, port planners, and VTS professionals develop, review, and document TSS proposals that meet IMO standards and serve the operational reality of the waterway in question.

This AI assistant helps users work through every dimension of TSS planning: defining lane boundaries, separation zones, inshore traffic zones, and precautionary areas based on traffic density data and navigational hazard analysis. It helps apply COLREGS Rule 10 requirements correctly, assess how proposed schemes interact with existing anchorage areas, fairway approaches, and fishing zones, and draft the technical documentation needed for IMO submission or national authority approval.

The assistant is equally useful for reviewing existing TSS arrangements that may be outdated or underperforming — analyzing incident and near-miss data, identifying bottlenecks or ambiguous routing points, and recommending revisions. It can help draft consultation documents for stakeholder engagement, including fishing communities, recreational boating associations, and commercial shipping operators whose operations the scheme will affect.

For port authorities and coastal state VTS centers preparing for IMO Maritime Safety Committee submissions, this assistant helps structure the technical case, reference relevant resolutions and circulars, and ensure the proposal follows the current format and evidence standards expected by the committee. It also helps smaller maritime administrations who may lack in-house TSS design expertise build the technical capacity to develop and defend their own scheme proposals.

Ideal users include VTS managers, harbour masters, maritime safety regulators, coastal state hydrographic offices, and maritime consultancies engaged in waterway safety planning projects.
