Operations & Capacity Model
(Concept-Level System Design) 

Cosmic Horizons is designed as a continuous, 

high-throughput transport system utilizing

dual load platforms, synchronized dispatch intervals, 

and non-interruptive accessibility integration.

The system is structured to maintain consistent flow, 

high capacity, and operational continuity while supporting

a calm, accessible guest experience across all age groups.

Design Intent

Cosmic Horizons is conceived as a high-capacity,

multigenerational space attraction

designed to balance awe, accessibility,

and long-term operational stability.

The experience is built around the idea that a journey

through the cosmos should be emotionally expansive 

rather than physically intense, allowing guests of all ages

to experience the scale and beauty of the universe together.

High-Capacity Design

Cosmic Horizons is designed from the outset as a 

high-throughput attraction, targeting throughput 

levels that exceed the highest-capacity 

continuous-load attractions currently in operation 

The system utilizes a continuous-moving transport

 architecture with dual alternating boarding platforms,

allowing guests to board from separate load zones

without interrupting the mainline vehicle flow. 

This configuration allows loading

and unloading operations to occur simultaneously

while maintaining consistent vehicle spacing 

and smooth ride pacing.

Vehicles are configured for eight passengers per unit, 

supporting multigenerational groups

while maintaining efficient boarding cycles.

With a projected dispatch interval of

approximately 3.2 seconds, 

the concept-level throughput model indicates

a theoretical capacity of approximately:

~7,650 guests per hour

This represents the target throughput

under optimized dispatch conditions. 

To account for real-world operational variability

including slower guest loading, accessibility boarding,

and natural fluctuations in guest flow—

a conservative operating model is also considered.

Under these conditions,

throughput would remain in the range of:

~6,100 – 6,400 guests per hour

This conservative scenario assumes:

• 4.0 second dispatch interval  

• 8 passengers per vehicle  

• 85% average load factor  

Even under these conservative assumptions, 

Cosmic Horizons would maintain throughput 

comparable to or exceeding—

many of the highest-capacity attractions

currently operating at major theme parks.

Guiding Principles 

From the earliest stages of the concept, 

the attraction was shaped by three principles:

Clarity of experience
The journey remains readable from every seat—

designed to be understood, not decoded.

Operational continuity
The system is built to move steadily,

 supporting high throughput without disrupting comfort.

Enduring design
Every element favors reliability and 

adaptability over short-term spectacle.

Together, these principles allow Cosmic Horizons

to deliver planetary scale and perspective—

while maintaining the calm, accessible

experience required of a truly shared journey.

MERGE BACK TO MAINLINE

Accessibility boarding occurs off the mainline,

allowing additional time without interrupting system flow. 

System Characteristics 

• Dual load symmetry maintains balanced guest flow
• Continuous dispatch ensures consistent ride pacing

• Accessibility is integrated without stopping vehicles

• Mainline merge creates a single controlled

   throughput stream
• System design prioritizes reliability and

   operational continuity 

Dispatch & Boarding Model 

Boarding Window Logic

Boarding time and dispatch interval

 are governed by separate system variables.

Effective boarding time ≈ platform length ÷ vehicle speed

Because the system utilizes dual alternating load platforms,

each vehicle receives extended boarding time

while maintaining a shorter dispatch interval.

The system decouples dispatch interval from 

boarding duration by using extended platform length

and dual alternating load zones.

Dispatch Interval Strategy 

Target Dispatch Interval
~3.2 seconds (optimized operation)

Sustained Operational Range
3.5–4.0 seconds (real-world conditions)

This range reflects typical operational variability

while maintaining high throughput and consistent ride pacing.

Operating Assumptions  

• Dispatch interval: 3.2–4.0 seconds 

• Seats per vehicle: 8 

• Load factor: 85% 

• Boarding system: dual continuous load platforms

• Accessibility: off-mainline spur with merge

Ride Duration & System Scale 

The attraction is designed with a total ride duration

of approximately 8 minutes, balancing forward motion 

with high-throughput operation and strong re-ride value.

Based on the modeled dispatch interval and

system timing, the ride operates with approximately:

•  117–146 vehicles on track 

•  Dispatch interval: 3.2–4.0 seconds 

•  Throughput: ~6,120–7,650 guests per hour 

• The resulting system supports a total track length

   of approximately: 2,100 feet 

This configuration aligns with high-capacity

continuous-load attraction systems 

while maintaining consistent pacing, visual clarity, and

 sustained guest engagement throughout the experience.

Capacity Model

The projected throughput is derived from 

a standard attraction capacity model

used to estimate hourly guest flow

in continuous-load ride systems.

PPH =

(3600 / headway seconds) × seats_per_vehicle × load_factor

Where:

• 3600 = seconds per hour
• headway_seconds = dispatch interval between vehicles
• seats_per_vehicle = passenger capacity of each vehicle
• load_factor = expected percentage of seats filled during

   normal operation

Using the concept model assumptions:

• headway = 3.2 seconds
• seats per vehicle = 8
• load factor = 0.85

PPH = (3600 / 3.2) × 8 × 0.85

PPH ≈ 7,650 guests per hour

This model represents the target operational throughput

under optimized  dispatch conditions.

A conservative operational scenario produces:

PPH ≈ 6,120 guests per hour

This dual-model approach reflects both theoretical system

capacity and practical operating conditions

typical of high-throughput theme park attractions.

Dispatch vs. Boarding Window Clarification

Dispatch headway and guest boarding time

are governed by separate design parameters.

Headway is determined by

vehicle spacing and safety block systems,

while boarding time is determined by

platform length and vehicle speed.

Because Cosmic Horizons utilizes

dual alternating load platforms,

each platform effectively receives

approximately 6.4 seconds of boarding time, 

even while vehicles continue dispatching

at the shorter headway interval.

This separation allows the attraction to maintain

high system throughput while preserving

calm and accessible boarding conditions for guests.

Accessibility Without Stopping the Mainline

Accessibility is integrated directly into the loading architecture.

Rather than stopping the mainline system for

accessibility boarding,

a secondary spur loading position provides

additional boarding time when required. 

Vehicles then merge back into the main transport sequence

without interrupting the overall ride flow.

This approach allows mobility devices, 

multigenerational groups, and guests

requiring additional assistance to board comfortably—

while preserving system throughput and operational rhythm.

Vehicle Design and Sightline Accessibility

Ride vehicles are configured with a raised rear seating row, 

improving sightlines so younger guests 

can clearly see past taller riders seated in front of them.

This configuration supports multigenerational viewing and

ensures that the visual storytelling remains readable 

from every seat position.

Vehicle motion is intentionally limited to

gentle pitch and yaw movements designed to

remain below common motion-stress thresholds. 

This allows the experience to deliver moments of

planetary scale and spatial awe 

while remaining comfortable for guests 

across a wide range of ages and sensitivities.

Scenic Technology Strategy

Large-scale planetary environments are achieved through

a combination of projection environments, 

volumetric lighting, and physical scenic forms—

rather than relying extensively on large LED sphere displays.

A limited LED sphere installation is envisioned 

within the Spaceport environment, 

where the Moon transitions into Mars and

other planetary bodies as part of the arrival sequence.

This selective use of LED technology balances visual impact 

with practical capital cost considerations while maintaining 

the realism and clarity of the attraction’s planetary environments.

Operational Durability 

Cosmic Horizons is designed with 

long-term operational stability as a primary objective.

Show environments are structured so that 

major scenic elements can be maintained or serviced

without interrupting the overall narrative sequence.

If a large scenic component requires maintenance,

the surrounding projection environment can 

temporarily represent the same celestial body

while repairs are completed.

This layered show strategy allows the attraction to

maintain a consistent guest experience 

while minimizing downtime and operational disruption.

The system is designed for high reliability and 

operational continuity over decades of service.

 Spatial Envelope & Building Fit

The attraction is designed to operate within a footprint

comparable to existing large-scale EPCOT attractions, 

utilizing a multi-level track layout to efficiently

distribute approximately 2,100 feet of ride path

within a compact show building.

The system uses a combination of:

• layered track routing 

• controlled scene density 

• expanded volumes for key environments 

to balance spatial efficiency

with moments of large-scale visual impact.

Lower levels support loading, early journey sequences, 

and transition scenes, while upper volumes are

reserved for larger cosmic environments such as 

planetary encounters and deep space sequences.

This approach allows the attraction to maintain

high capacity and narrative clarity

while fitting comfortably within a footprint

similar to the existing Mission: SPACE facility.
