While this chapter focuses on capacity concepts and analysis methods for vehicles, the capacity concepts and analysis methods related to passenger facilities and throughput presented in Chapter 3 also apply to most ferry services carrying vehicles and walk-on passengers. Quantitative procedures outlined in Chapter 4 include those presented in the discussions of Equation 3: Using AEU to calculate vehicle capacity of the vessel, Equation 4: Estimating vehicles left behind, and Equation 5: Sizing vehicle fare collection facilities.

Optimizing Capacity with Demand Management For vehicle ferry services, vehicle capacity is often reached before passenger capacity. Because of this, shifting riders from their vehicles to walking on the ferry or spreading the peak vehicle demand can help increase the capacity of the system to serve more people without requiring capital investment in new vessels.

Examples of how different vehicle ferry systems manage bicycles are shown in Table 17. Understanding Vessel Capacity and Vehicle Demand The number of vehicles a vehicle ferry can carry depends on several factors, including route specific trends in volume and type of vehicle demand as well as the vessel capacity and design.

Typically on vehicle ferries, crews direct vehicles onto the ferry and assist drivers in parking as close to the vehicle in front as possible (leaving escape route space between every vehicle or few vehicles as designated by the Coast Guard requirements for that vessel) in order to maximize capacity and minimize the vehicle loading time.

Vehicle Terminal Capacity Planning and Minimizing Dwell Time Capacity planning for vehicle ferry terminals focuses on how many vehicles can be held after fare processing, how they are sorted prior to loading, and how quickly they can load and unload the vessel. Habib et al.

Figure 8 illustrates considerations that affect how much terminal space and how many holding lanes are needed, as well as potential uses that may be given designated lanes or priority loading. Expediting Fare Collection and Passenger Counting Fare collection methods and technologies used and the location of fare collection relative to vehicle holding or loading can affect the dwell time and overall capacity of the ferry system.

Tracking and queue monitoring collects queue length data to inform analysis of queue length data would route and terminal capacity planning require dedicated staff time.

For terminals serving multiple routes, additional holding area capacity and fare processing capacity are required to process vehicles arriving at the terminal for different sailings. Equation 5. Sizing vehicle fare collection facilities.
