Urban Traffic Control
While the STREAMS ITS Platform features its own Urban Traffic Control (UTC) system, a unique attribute of STREAMS is its ability to interface with other urban traffic control systems such as SCATS®. As a result, customers can realise the benefits of an integrated ITS platform while still maintaining use of their existing UTC system through a customised interface.
STREAMS’ own UTC system operates in Queensland, Australia and optimises the routes, intersection groups, intersections and movements within a road network to ensure they operate in synergy and enhance traffic flow. It is a dynamic system that automatically responds to changes in current traffic conditions.
Improved level of service at intersections
Reduced exhaust emissions
Reduced stops, delays and queues
Reduced travel times
Increased fuel effiency
The STREAMS UTC is provided as part of the integrated STREAMS ITS Platform, and has a range of features that help optimise routes, intersections and movements within a road network.
Interface to SCATS®
The STREAMS interface to SCATS® adds significant value to SCATS® adaptive traffic control software installations to maximise transport road network efficiency.
STREAMS is an ITS integration platform that interfaces with SCATS® and is also capable of:
- managed motorways: lane use management system (LUMS), ramp management, incident management
- dynamic message signs, schematics, variable speed limit
- vehicle detector
- SCADA integration
- urban traffic control
- parking guidance
- construction site management
- vehicle priority and pre-emption
Features and benefits
The SCATS® interface delivers immediate user benefits, even prior to integrating other ITS devices or systems. It requires minimal setup and provides sophisticated automation of the creation of SCATS® configuration data. With a STREAMS system in place that can meet all of a customer’s ITS requirements, operators can begin to enjoy immediate benefits while engineers migrate legacy equipment such as variable message signs to the new platform.

Emergency Vehicle Pre-emption
In an effort to address the increasing demand for emergency services, the Queensland Government including the Department of Community Safety worked collaboratively with Transmax to develop the EVP solution.
Emergency Vehicle Priority (EVP) tracks the location of ambulance and ﬁre emergency vehicles responding to emergency call outs. It uses computer-aided dispatch, GPS and traffic management technology to determine the location of an emergency vehicle, calculate estimated times of arrival at intersections and send a message to the traffic control system that an emergency vehicle is approaching. The traffic control system then provides a green light in advance of the arrival of the vehicle at the required traffic signal when it is safe to do so.
Transmax developed new STREAMS functionalities speciﬁcally for EVP including dynamic interventions for minimal traffic impact, pedestrian clearance protection, live monitoring at traffic management centres, and user-conﬁgurable recovery algorithms.
Who benefits from EVP?
- Reduces travel time by providing priority for emergency services through traffic signals
- Reduces the number of times an emergency response vehicle (ERV) needs to cross intersections against the lights
- Improves incident clearance rates
- Helps emergency response personnel meet response targets
- Assists ERVs to more efficiently manage increasing traffic demands
- Assissts in safely and effectively responding and attending to emergency incidents
- Reduces noise pollution as EVP allows ERVs to operate in ‘lights only’ mode more frequently
- Provides a safer work environment for front-line officers
- Reduces likelihood of accidents during emergency responses
- Reduces the need to increase the number of front line-officers or ERVs to maintain service levels
- Improves resource efficiency
- No change to front-line officer business procedures required to use the system
- Minimises installation and maintenance costs for road authorities by using existing infrastructure
- Minimises impact on other road traffic
- Allows a policy-based approach to giving priority to special classes of road users (like emergency vehicles)
- EVP can be adapted for other usrers in the future such as buses and heavy vehicles
- Promotes inter-agency collaboration
- Contributes to lives being saved by assisting ERVs to progress to incidents more efficiently
- Improves safety of drivers, pedestrians and other road users
