Vehicle headway is a measurement of the time interval between two vehicles traveling in the same direction along the same route. A shorter headway corresponds to more frequent service. Vehicle headways are measured in minutes (e.g., every 60 minutes). Indian River County has the same frequency of service standard for all routes, with the only exception being for routes that provide regional or intercity service. All GoLine routes operate on 60 -minute headways. Currently, only one vehicle operates on a GoLine route at any given time. Reducing vehicle headways (i.e. increasing frequencies) would require adding a second vehicle to each affected route. Because increasing frequencies will require increasing the size of the GoLine fleet, it will involve capital costs as well as operating costs. Due to the limited resources available to a transit system operating in a county of only 156,000 residents, it is not financially feasible to reduce headways at this time. In the future, if vehicle headways are reduced, it would be implemented on a group of connected routes with high levels of ridership. On -Time Performance On-time performance is a measure of runs completed as scheduled. This criterion first must define what is considered to be "on time." An acceptable level of performance must be defined (expressed as a percentage). Indian River County strives to continually maintain on-time bus service. Because of the "hub and spoke" design of the GoLine route system, it is critical that buses consistently operate on-time. Every hour, GoLine buses connect with each other at five transfer locations: the Main Transit Hub (seven routes), Indian River Mall (five routes), the North County Hub (four routes), the Intergenerational Center (four routes), and the Gifford Health Center (three routes). Whenever one bus falls behind schedule, it can cause delays on all vehicles that operate on connecting routes. Therefore, County and SRA staff evaluate on-time performance on an ongoing basis and implement service changes to improve performance, as necessary. On-time performance is defined as a bus arriving at a scheduled time point within five minutes of the scheduled arrival. During FY 21/22, GoLine buses arrived on-time 95.7% of the time. Through the first quarter of FY 22/23, on-time performance has remained steady at 95%. Service Availability Service availability is a general measure of the distribution of routes within a transit provider's service area. For example, a transit provider might set a service standard to distribute routes such that a specified percentage of all residents in the service area are within a one-quarter mile walk of bus service or a one-half mile walk of rail service. A standard might also indicate the maximum distance between stops orstations. These measures related to coverage and stop/station distances might also vary by population density. Service availability is a measure of the distance a person must travel to gain access to transit service. Based on an analysis of the GoLine route network using 2020 Census data, it was determined that 47% of Indian River County residents live within % mile of a fixed route and 83% are within 3/ of a fixed route.
