Safety Performance Measures – 673.11(a)(3)
The PTASP Final Rule, 49 CFR Part 673.11(a)(3), requires that all public transportation providers must develop an ASP to include SPTs based on the safety performance measures established under the NSP. The safety performance measures outlined in the NSP were developed to ensure that the measures can be applied to all modes of public transportation and are based on data currently being submitted to the NTD. The safety performance measures included in the NSP are fatalities, injuries, safety events, and system reliability (State of Good Repair as developed and tracked in the TAM Plan).
There are seven (7) SPTs that must be included in each ASP that are based on the four (4) performance measures in the NSP. These SPTs are presented in terms of total numbers reported and rate per Vehicle Revenue Mile (VRM). Each of the seven (7) are required to be reported by mode as presented in Table 4.

Table 5 presents baseline numbers for each of the performance measures. PBT collected the past four (4) years of reported data to develop the rolling averages listed in the table.

While safety has always been a major component of the PBT operation, the adoption of this ASP will result in changes across all aspects of the organization. The SPTs set in Table 6 and Table 7 reflect an acknowledgement that SMS implementation will produce new information that will be needed to accurately set meaningful SPTs. We will set our targets at the current NTD-reported four-year average as we begin the process of fully implementing our SMS and developing our targeted safety improvements. This will ensure that we do no worse than our baseline performance over the last four years.

As part of the annual review of the ASP, PBT will reevaluate our SPTs and determine whether the SPTs need to be refined. As more data is collected as part of the SRM process discussed later in this plan, PBT may begin developing safety performance indicators to help inform management on safety-related investments.
