PURPOSE
    Define a formal AI-readable ontology for Transportation Engineering,
    including transport systems, networks, roads, railways, junctions,
    terminals, vehicles, travellers, demand, capacity, traffic flow,
    speed, density, travel time, safety, geometric design, pavements,
    signalling, operations, public transport, freight, accessibility,
    environmental effects, maintenance, provenance, uncertainty,
    confidence and recursive transportation reasoning.

CORE_DEFINITION
    Transportation Engineering is the civil-engineering discipline
    concerned with planning, designing, operating, analysing and
    maintaining transport systems and infrastructure for the movement of
    people and goods with defined levels of safety, capacity,
    accessibility, reliability and service.

    Critical Distinction
        Transportation engineering must distinguish demand from capacity,
        speed from flow, accessibility from mobility and design capacity
        from a safe operating level. Traffic and safety evidence must
        retain network location, transport mode, exposure and time-period
        context.

RECOMMENDED_AI_SUMMARY
    Transportation Engineering plans, designs, operates and maintains
    transport networks for moving people and goods. Reliable reasoning
    preserves transport mode, network and link identity, demand periods,
    traffic measurements, capacity assumptions, geometric and control
    conditions, safety exposure and asset condition while distinguishing
    demand from capacity, speed from flow and infrastructure capacity from
    safe or desirable operating conditions.
