Annual Boardings Linear Trend

how to read… SeaBus Route

Summary(1 of 3)

Number of people who live or work in the vicinity (800m buffer) of the two SeaBus terminals. Population and employment densities are key contributors to ridership.

The Frequent Transit Network (FTN) is a network of corridors where transit service runs at least every 15 minutes in both directions throughout the day and into the evening, every day of the week.

One-way route length (from Waterfront Stn to Lonsdale Quay).

Number of boardings associated with the service. Does not consider transfers between services.

The estimated cost of service per year (Annual Revenue Hours x Average Cost per Service Hour).

Number of hours the SeaBus is ‘in-service’ (including recovery time but excluding deadheading).

The estimated service cost per boarded passenger (Annual Service Cost / Annual Boardings).

Industry standard measure of ridership versus transit supply.

SeaBus cost and performance metrics have been ranked among the equivalent metrics from the bus route summaries. This offers a sense of comparison and represents the order of magnitude between the two service modes.

Number of people who board the service, organized by day type.

How many people are on board a SeaBus vessel on an average trip (the SeaBus has a capacity of 385 passengers).

A ratio of vehicle occupancy versus capacity (Peak Passenger Load / Vehicle Capacity), where a factor of 100% means a full vessel.

Summary of service changes implemented between December 13, 2010, and December 20, 2015. Service changes are implemented to address issues related to route performance.

Summary of special events in 2015 for which additional SeaBus sailings were added (including increased frequency and extended hours of operation).

A visual representation of Annual Boardings from the “Cost and Performance” section. The linear trend is a line of best fit for all points in the chart. The historical linear trend value (%) represents the slope of the line of best fit.

Summary(2 of 3)

The SeaBus experiences strong seasonal variations in ridership due to tourism, recreation, and other special events. In recognition of increased ridership, Sunday daytime frequencies are doubled over the summer.

Due to the seasonal variations in ridership, performance tables are presented for both the Summer and Fall periods. This is a unique feature among all the modes included in the Transit Service Performance Review.

These columns utilize the same data and metrics from the previous page but offer a greater level of detail. The tables illustrate productivity by day type and time period. Colour coding helps to track changes in performance over time and categorize SeaBus performance in quartiles relative to the service’s performance across different day types or times of day.

Unlike the bus route summaries, the quartiles represented through the colour coding are based on SeaBus performance exclusively.

These columns describe the service levels offered during each time period in terms of revenue hours and the average number of trips per hour.

The SeaBus has a capacity of 385 passengers. These figures represent average passenger loads by time period and direction (northbound / southbound). Due to Transport Canada regulations, SeaBus capacity cannot be exceeded and terminal turnstiles will automatically lock once the vessel capacity is reached.

Summary(3 of 3)

Due to the seasonal variations in ridership, hourly passenger volume and capacity charts are presented for both the Summer and Fall periods. This is a unique feature among all the modes included in the Transit Service Performance Review.

Charts demonstrate average hourly passenger volume and capacity by day type for the given season (Summer/Fall). Averages are calculated at the clock hour, for all scheduled sailings within the hour.

Passenger volume and capacity charts are presented for both directions of service (Southbound to Waterfront / Northbound to Lonsdale).

Performance data is displayed for the mainline and for each branch.

The greatest 60-minute passenger volume for the given time band (sum of passenger volume for a train and all following trains arriving in the next 60-minutes). This peak 60-minute interval may occur at any time within the given time band and is independent of any clock hour.

Average number of trips per hour per direction for the given time band.

Colour coding represents what percentage of train capacity is utilized at the peak link, i.e. how full trains are at the busiest point on the given line segment, compared to the train capacity (Average Passengers per Train / Average Train Capacity).

The station pair observed to have the greatest in-train passenger volumes for the given time band. Passenger loads between the two stations listed are the greatest for the given line segment. Order of station pair indicates peak direction.

Average Passengers per Train (Passengers per Hour / Average Trips per Hour). Actual passenger loads are likely to vary and may not represent observed loads.

Charts are provided for each direction of service. Passenger volumes shown are for this direction of travel.

Total (all-day sum) of in-train passenger volumes for trains traveling between the identified station pairs in the given direction.

Only select stations were surveyed in 2015, while in 2011 all stations were surveyed during weekdays. No weekend surveys were conducted in 2011.

Stations were surveyed on different dates, and normal day-to-day variations in ridership may be present.

Disruptions in service or other anomalies that may have affected sampling are described below the chart. Sports events, concerts, and other large events are commonplace and occurred on many survey dates; these may or may not be listed on each station summary.

60-minute sum of in-train passenger volumes/capacity, for each observed train as it departed the station in the given direction.

Only select stations were surveyed in 2015, while in 2011 all stations were surveyed during weekdays. No weekend surveys were conducted in 2011.

Data points on the chart have been plotted on a time scale x-axis. Every point on the chart represents the sum of passenger volumes/capacity for an observed train and all following trains departing in the 60-minutes after that train.
