Associated Objectives and Performance Measures

Objective Performance Measure
Annual rate of change in regional average commute travel time will not exceed regional rate of population growth through the year Y. Average commute trip travel time (minutes).
Decrease system-wide signal delay on transit routes by X percent per year. System-wide signalized stop delay on transit routes.
Improve average on-time performance for specified transit routes/facilities by X percent within Y years. On-time performance of transit.
Improve average transit travel time compared to auto in major corridors by X minutes per year for Y years. Transit to auto travel time differential for a given period (daily, hourly, or peak hours), on a given portion of the system (system wide, by facility type, or by corridor).
Improve average travel time during peak periods by X percent by year Y. Average travel time during peak periods (minutes).
Increase implementation of transit signal priority strategies on X number of routes (or X number of intersections) over the next Y years. Number of transit routes/intersections equipped with transit signal priority capability.
Maintain a travel time differential between transit and auto during peak periods of X percent for Y years. Transit to auto travel time differential for a given period (daily, hourly, or peak hours), on a given portion of the system (system wide, by facility type, or by corridor).
Reduce excess fuel consumed due to congestion by X percent by year Y. Excess fuel consumed (total or per capita).
Reduce hours of delay per capita by X percent by year Y. Hours of delay (person-hours).
Reduce hours of delay per capita by X percent by year Y. Hours of delay per capita.
Reduce the regional average travel time index by X percent per year. Travel time index (the average travel time during the peak period, using congested speeds, divided by the off-peak period travel time, using posted or free-flow speeds).
Reduce the travel time differential between transit and auto during peak periods by X percent per year for Y years. Transit to auto travel time differential for a given period (daily, hourly, or peak hours), on a given portion of the system (system wide, by facility type, or by corridor).
Reduce total energy consumption per capita for transportation by X percent by year Y. Total energy consumed per capita for transportation.
Reduce total fuel consumption per capita for transportation by X percent by year Y. Total fuel consumed per capita for transportation.
Reduce vehicle miles traveled per capita by X percent by year Y. Average VMT per capita per day, per week, or per year.

 
Since the mapping between objectives and service packages is not always straight-forward and often situation-dependent, these mappings should only be used as a starting point. Users should do their own analysis to identify the best service packages for their region.
