EMTRAC for Bus Rapid Transit (BRT)

The EMTRAC system enhances the following “essential features that define BRT”^[2]—without requiring additional hardware:

Dedicated Right-of-Way and Busway Alignment: EMTRAC-equipped vehicles are able to automatically open entrance gates to dedicated BRT lanes.

Off-Board Fare Collection: Vehicles may request signal priority at near-side stops (depending on door status) or while approaching far-side stops (depending on stop-request status).

Intersection treatments: In addition to signal priority, precision vehicle detection allows for lane-specific actuated phasing.

Platform-Level Boarding: Account for faster loading times by customizing the conditions under which priority is requested. As a result, signal phases are not altered until necessary.

Transit agencies are also able to monitor real-time BRT activity with the EMTRAC Central Monitor system.

BRT Features

Industry-best satellite and inertial positioning enables vehicles to request signal priority by lane.
Equipped vehicles can automatically open busway and garage entrance gates, without requiring additional onboard hardware.
Route timepoints may be automatically reported by vehicle, with timepoint data saved to detailed activity logs.
Central Monitor software displays vehicle activity in real time on interactive map.
Vehicles are easily configured to allow signal priority only under specified conditions.

BRT Benefits

Timeliness: Vehicles behind schedule may be configured to continue requesting signal priority until they are back on schedule.
Ease of Installation: EMTRAC BRT equipment is the same as used for other EMTRAC applications.
Expandability: Agencies can upgrade their existing EMTRAC system with minimal effort, adding capabilities as schedules and budgets allow.
Flexibility: Install additional components for specific vehicles (or vehicle classes). For example, install EMTRAC Control Heads (to provide driver alerts) only on rapid-transit buses.
Accuracy: The EMTRAC system utilizes the most precise vehicle-position technology to ensure exact location reporting—even in unfavorable urban environments.
Security: Frequency-Hopping Spread Spectrum radio signal has superior range and utilizes AES encryption.
