209 In the current state-of-the-art APM system planning there is a range of modeling tools that are applied during the predesign phase of the work. These tools are all facilitated by computer-based analyses intended to study the operating conditions that the APM system will serve.

Station Activity Analysis When the planning analysis has first predetermined the criteria/goals of the APM system capacity to be provided relative to the peak demand conditions, the simulation modeling tool can then assess the impacts on the passengers waiting in the station, both during the peak demand interval and throughout the day. Figure E-4 shows the results of a simulation model's 24-hour accumulation of station waiting time -- i.e., the time until the passenger was able to board a train.

demand during peak intervals and/or the station having a location that is significantly impacted by operating conditions where some trains arrive completely full, not allowing all passengers to board. Based on the simulated ridership, associated with pedestrian flows and system capacity limitations, models are used to assess the dynamic station operating conditions that result and the related level of service provided within each element of the passenger's travel path -- the passenger experience provided by the APM.

concourse will determine the unique demand patterns by time of day; and • At stations serving specific landside facilities such as rental car facilities, the patterns of mode split with respect to car rentals and returns by time of day, thereby changing the distribution of boarding and alighting demands. Operational Impacts Simulation models have other application aspects that can be very beneficial to analyzing the station facilities, vertical circulation elements, and short-duration ridership demand loads.

System Operations Analysis The final area for which simulation models are often used in the planning phase of study concerns the analysis of the whole system's operations.
