When an unplanned incident occurs on a road network, it may decrease safety for road users, increase congestion and travel times, and cause secondary incidents. According to National Traffic Incident Management Coalition (NTIMC), 25% of congestion on United States road networks is caused by traffic incidents.
STREAMS SIMS is used by traffic management centres (TMCs) to manage road networks through detection, verification, logging, and response to: unplanned incidents such as accidents; planned events such as roadwork; and equipment faults. It enables road authorities to efficiently detect, respond to, and clear incidents to restore normal traffic conditions as safely and efficiently as possible.
SIMS reduces the impact of incidents and faults by providing:
- Verification and logging of incident details
- Location-based logging
- Device-based fault identification
- Cross-regional and cross-organisational handover of incidents and events
- Flexibility in multiple operator access to managing incidents and events
- Automatic customisation of generic response plans to create tailored response plans for each incident
- Reports that facilitate the review of trends and performance, leading to improved response and cost savings.
Benefits of SIMS
SIMS improves the response to incidents which reduces recovery times. Quick and effective response to incidents is critical because, for every minute an accident remains uncleared, it typically takes an additional four minutes for traffic to recover.
How SIMS works
Operators can use SIMS to quickly and efficiently record all reported incidents and equipment faults. CCTV surveillance cameras can also be managed by STREAMS to assist with incident and fault detection and verification.
Incident logging can be undertaken by many operators at the same time. Operators make use of a shared ‘Handover Manager’ between different traffic management centres to effectively coordinate cross-regional or cross-organisational incidents and events or to effectively transfer control of an incident to the next operator on shift.
Incident response is based on a set of generic response plans predefined for each type of incident. The appropriate generic response plan is automatically customised during the incident logging and verification process.
Response actions include:
- Messages to emergency and other service providers
- Traveller information via variable message signs, SMS and websites
- Diversion routes with signal coordination
- Ramp metering, variable speed limit signs and lane use management
- Vehicle priority and pre-emption.
A traffic management centre incident, fault and call log report can be generated by SIMS for post-incident reviews.
Where it is possible to determine responsibility for damage to equipment as a result of an incident, the system allows the recording of such details, including costs associated with the repair.
SIMS can log all incoming and outgoing telephone calls, which can be used to generate reports on traffic management centre operations. Call logs are a useful tool for both budgeting and risk management.
Current incident information is provided to the public through websites such as the Queensland Government’s 13 19 40 traffic and travel information site.
