Traffic scenario comparison

Reference data shows harbour visitors, including passing traffic, during the assumed 10:00–12:00 window. Sources: MATSim network and events · hvv timetable. MATSim vehicle counts are expanded from a 10% sample to estimate full traffic; scheduled hvv buses are added for modal split and traffic trend. Boundary crossing times are approximate, and MATSim covers a wider road network.

* Modal split. Share of visiting journeys by vehicle category. Differences and the ±5% range are relative to each category’s reference share.

† Hourly traffic trend. Vehicles inside as a percentage of each series’ total visiting journeys. Total load counts each journey once, including unfinished journeys and those that leave and return.

§ Trip duration distribution. Completed car, van and truck journeys in five-minute ranges. Unfinished journeys and buses are excluded. The % button switches between trip counts and each series’ share of its own completed road journeys; both curves use the same percentage axis.

‡ Daily CO₂ emissions. Simulation projected to 24 hours at the same average rate. Reference: 2018 annual estimates ÷365. Vehicle categories and areas differ; historical context is shown only for the supplied harbour boundary, and missing category references are labelled unavailable. No bus reference. The car ÷ button switches to capture-period kg CO₂ per distinct boundary visitor, including zero-emission visitors, without daily scaling. Empty categories show N/A. Per-vehicle references are synthetic illustrative placeholders: light vehicles 1.5, trucks 4.0, buses 5.0 kg/vehicle, not measured or calibrated values. Source: HPA road traffic report.
