122 9.1 Overview Data analysis provides insight into how the buses are performing in your service area and if they are being fully utilized. The results can inform operational changes that will allow you to get the most out of your ZEBs, help you understand the true costs and benefits of the deployment, and inform future needs for a ZEB fleet.

Data Monitoring and Evaluation 123 9.2 Key Stakeholder Considerations Project Managers • Develop reports, as requested from executive leadership and transit agency staff, and as required by federal, state, or local funding sources used to support the ZEB deployment. • Coordinate with bus and infrastructure OEMs, electric utility providers, and operations and maintenance staff to establish data collection procedures for ongoing reporting.

124 Guidebook for Deploying Zero-Emission Transit Buses 9.3 Data Collection and Reporting After your ZEB fleet is in revenue service, collecting and analyzing bus data will help you better understand the performance, reliability, durability, and cost of your deployment. Evaluating the performance and limitations of the technology allows you to determine the most effective and efficient use of the buses throughout your service area.

Data Monitoring and Evaluation 127 • Availability (Figure 9-4) : Availability will indicate know how often the ZEB fleet was able to be put into service.

128 Guidebook for Deploying Zero-Emission Transit Buses Your transit agency can define additional categories if helpful, such as "Road Call for Low SOC." Reporting availability monthly will allow you to track maintenance issues that kept buses out of service. ZEB availability may be dependent on charging or fueling infrastructure availability.

From page 129... ...
Data Monitoring and Evaluation 129 • Fleet comparison (Figure 9-5) : Comparing the performance of the ZEB fleet to the diesel, CNG, or hybrid fleets informs relative cost and performance.

130 Guidebook for Deploying Zero-Emission Transit Buses The environmental benefits of ZEBs are a driving force for many transit agencies' deployment projects (Figure 9-6)
|
From page 131... ...
Data Monitoring and Evaluation 131 • Lifetime costs analysis (Figure 9-8 and Figure 9-9) : Compare the actual operating and maintenance costs to the projected costs throughout the service life of the fleet.

132 Guidebook for Deploying Zero-Emission Transit Buses 9.4 Data Sources You may need to collect data from several, disparate sources to support robust data reporting for your ZEB fleet. • Utility bills: Use the total costs from your electricity bills to calculate fuel costs per mile.
|
From page 133... ...
Data Monitoring and Evaluation 133 • Asset management systems and maintenance reporting systems: Your maintenance department will have information on vehicle service needs, parts and labor costs, and reasons for a bus being out of service to inform fleet availability and maintenance costs. • Operations reporting systems (e.g., TransitMaster, Clever Devices, FLEETWATCH, HASTUS)
