Central control
Unitrans’s centralised control tower continuously monitors the movement of vehicles through satellite tracking technologies and GPRS information transfer. It mitigates on-road risk and drives productivity through tracking vehicles against defined planned routes and managing them through live exception-based reporting. The facility also contributes towards increased operational efficiencies and productivity.

The control tower adds value to Unitrans and its customers and can be fully integrated into customers’ supply chains. It assists in managing receiving and dispatch points, and improves supply chain management through visibility, information availability and reporting.

The control tower:

  • monitors vehicles for speeding, driving hours and route adherence against each journey’s management plan;
  • responds to potential accidents through impact alerts and panic alarms;
  • predicts times of arrival, allowing for off-load scheduling and customer planning;
  • assists in mitigating the risk of theft and hijackings of goods in transit; and
    ensures load integrity.

Vehicle technology
New-generation trucks include technology options that significantly
increase the safety of vehicles for all road users.

Collision Avoidance Technology and Automatic Emergency Braking (AEB), using forward-facing integrated radar, detects speed differences between the truck and other objects in its path. It assists in avoiding a collision by warning the driver of a possible collision or by automatically applying the brakes of the vehicle. These two systems help to avoid incidents and reduce the severity of an accident when unavoidable – by reducing the velocity of the vehicle in order to reduce the impact.

Roll Stability Systems (RSS) and Electronic Braking Systems (EBS) prevent vehicles from jackknifing and assist in reducing vehicle rollovers. This is achieved by comparing tyre revolution speed across axles and applying the vehicle’s brakes differentially across the axles, which stabilises and straightens out a vehicle and maximises the possible braking force. This technology is employed on both prime movers and trailed units.

DriveCam is installed in all Unitrans on-road prime movers. The DriveCam system is triggered and immediately generates an in-cab-facing video when any of the specified parameters are exceeded, such as speeding or harsh breaking, and when potential impact is identified. These clips are 12 seconds long – initiating four seconds before the G-force trigger point is reached, and eight seconds afterwards. This video clip is then analysed, reported on
and categorised. DriveCam is used to manage drivers and incidents, and to identify high-risk drivers and risky behaviour that could lead to an incident. It has also been used extensively to understand the causes that led to incidents and accidents. Further developments, which are showing positive results, include proactive fatigue and distraction detection.
