Transit operations decision support systems (TODSS) reduce false and low priority incident reports sent to dispatchers by 60 percent, allowing dispatchers to focus on higher priority incidents.
Based on the evaluation of the TODSS prototype development at Pace Suburban Bus in Northern Illinois.
This evaluation was done by analyzing data from Pace's existing Intelligent Bus System (IBS) before and after the addition of TODSS software. The IBS includes automatic vehicle location (AVL), computer-aided dispatch (CAD) and operations taken by dispatchers. The system was also evaluated with surveys of dispatchers, supervisors and administrators before and after TODSS implementation to assess the impact of TODSS on the work environment.
The introduction of the TODSS system reduced the number of incidents in the dispatchers' queues by over 60 percent because the system design reduced the number of false or less important errors and focused dispatcher efforts on important incidents. Voice communications initiated by drivers sent to dispatchers decreased by 30 percent, allowing drivers to focus more on driving while alerting dispatchers to issues through canned text messages. These canned messages are set up to generate specific responses within the TODSS system and prioritizes them for the dispatchers.
The service development and scheduling groups at Pace access historical data which includes the types of service disruptions and the adjustments made through TODSS. This allows them to be sure to provide appropriate run-times or prove the need for re-routing. The ability of administrators to audit dispatchers based on TODSS is used to measure and improve the level of dispatcher performance. Traveler Services receives more timely and accurate information about service disruptions which, in turn, provides passengers with more accurate real-time information.
