Destination-Based Dispatching (DD) – Smartrise Engineering

Overview

Destination-Based Dispatching (DD) is an advanced elevator passenger routing system that optimizes travel efficiency by grouping passengers based on their desired floor destinations before they enter an elevator car. Rather than calling an elevator with a traditional up/down button, passengers select their destination on a touchscreen or keypad in the hall. The system then determines the best car assignment based on real-time traffic conditions, reducing wait times, improving travel times, and minimizing congestion — especially during peak periods.

How It Works

Passengers use a touchscreen or keypad to enter their desired floor before boarding.
The DD system analyzes traffic and matches each request to the most suitable elevator car based on current car locations, direction, and capacity.
This system continuously analyzes real-time origin and destination data to optimize assignments dynamically and reduce unnecessary stops.
Assignments can consider multiple dispatch algorithms — such as nearest car, time-to-pickup, time-to-destination, or total cost — for smarter, traffic-aware dispatching.

System Configuration Options

Flexible Implementations

Lobby-Only Destination Entry:
Install touchscreens or keypads at the lobby to direct traffic during high-volume periods, while using traditional up/down buttons on other floors.
Full Destination System:
Install destination entry devices on every floor to achieve a complete destination-based system.

Key Benefits

Operational Benefits

Reduced Wait Times: Direct destination selection reduces intermediate stops and speeds up trip assignments.
Better Traffic Handling: Optimizes passenger grouping and dispatching based on real-time conditions.
Improved Travel Efficiency: Fewer stops and smarter assignments improve overall elevator performance.
Lower Operating Costs: More efficient traffic patterns can reduce energy use and long-term wear.

User Experience

Intuitive Interaction: Destination entry at kiosks feels intuitive and personalized for users.
ADA Accessibility: The system can include voice guidance and ADA-friendly interfaces to assist visually impaired passengers.
Flexible Passenger Routing: Suitable for mid- and high-rise office buildings, hotels, residential towers, and other high-traffic environments.

Typical Use Cases

High-Rise Office Buildings: Improve traffic flow during rush hours.
Hotels & Residential Towers: Offer personalized elevator routing for guests and residents.
Mixed-Use Properties: Efficiently manage complex travel patterns across multiple demand peaks.

System Features

While implementations vary by install, common DD features include:

Support for up to 96 floors and multiple kiosks per floor (e.g., up to eight).
Field-adjustable configuration parameters to fine-tune system behavior on site.
Security options such as passcode entry and integration with card readers or third-party security systems.
Advanced traffic handling features like VIP service, split group operation, and hybrid configurations.
ADA accessibility support, including extended door times and guidance annunciations.

Integration & Support

The Destination-Based Dispatching system integrates with Smartrise elevator controllers and can be added as an optional component to new installations or modernizations.
