Associated Objectives and Performance Measures

Objective Performance Measure

Decrease the average buffer index for (multiple routes or trips) by X percent over Y years. The buffer index represents the extra time (buffer) most travelers add to their average travel time when planning trips. This is the extra time between the average travel time and near-worst case travel time (95th percentile). The buffer index is stated as a percentage of the average travel time. Average buffer index or buffer time can be calculated using miles traveled as a weighting factor. Buffer time = 95th percentile travel time (min) – average travel time (min).
Decrease the buffer index for (specific travel routes) by X percent over the next Y years. The buffer index represents the extra time (buffer) most travelers add to their average travel time when planning trips. This is the extra time between the average travel time and near-worst case travel time (95th percentile). The buffer index is stated as a percentage of the average travel time.

This is the extra time between the average travel time and near-worst case travel time (95th percentile). The buffer index is stated as a percentage of the average travel time. Average buffer index or buffer time can be calculated using miles traveled as a weighting factor. Buffer time = 95th percentile travel time (min) – average travel time (min).

Reduce the average planning time for (specific routes in region) by X minutes over the next Y years. The planning time index represents the time that must be added to travel time at free-flow speeds or the posted speed limit to ensure on time arrivals for 95 percent of the trips. Planning time = 95th percentile travel time (minutes) – Travel time at free-flow speed or posted speed limit. Average planning time index or planning time can be computed using a weighted average over person miles traveled.
Reduce the average planning time index for (specific routes in region) by X (no units) over the next Y years. The planning time index represents the time that must be added to travel time at free-flow speeds or the posted speed limit to ensure on time arrivals for 95 percent of the trips. Planning time = 95th percentile travel time (minutes) – Travel time at free-flow speed or posted speed limit. Average planning time index or planning time can be computed using a weighted average over person miles traveled.

Reduce the percentage of vehicles traveling through work zones that are queued by X percent in Y years. Percentage of vehicles experiencing queuing in work zones.
Reduce the person hours (or vehicle hours) of total delay associated with work zones by X percent over Y years. Person hours (or vehicle hours) of delay associated with work zones.
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 variability of travel time on specified routes by X percent during peak and off-peak periods by year Y. Variance of travel time. Variance is the sum of the squared deviations from the mean. This can also be calculated as the standard deviation of travel time. Standard deviation is the square root of variance.
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 total person hours of delay (or travel-time delay per capita) by time period (peak, off-peak) caused by all transient events such as traffic incidents, special events, and work zones. Total person hours of delay during scheduled and/or unscheduled disruptions to travel.
Reduce total person hours of delay (or travel-time delay per capita) by time period (peak, off-peak) caused by scheduled events, work zones, or system maintenance by x hours in y years. Travel time delay during scheduled and/or unscheduled disruptions to travel.

 
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.

The following discusses how the National ITS Architecture provides the transportation service described by this service package. Each numbered item describes the operation of that portion of the service package identified with the corresponding number on the transaction set diagram.

  1. Asset Management provides asset restrictions to the Maintenance and Construction Management Subsystem (MCMS). The restrictions may include standard height, width, and weight restrictions by facility and special restrictions such as spring weight restrictions and temporary bridge weight restrictions. These current asset restrictions are provided to the following center subsystems:

    • Commercial Vehicle Administration

    • Emergency Management

    • Information Service Provider

    • Traffic Management

    • Transit Management

    Some of the possible uses of this information by the receiving subsystems are: route selection and CVO clearances for too large or oversized vehicle limits.

  2. One of the key functions of the MCMS is to plan maintenance and construction activity. These maint and constr work plans are then disseminated to the following center subsystems and other key terminators:

    • Emergency Management

    • Information Service Provider

    • Media

    • Multimodal Transportation Service Provider

    • Rail Operations

    • Traffic Management

    • Transit Management

    It is expected that the following entities will provide work plan feedback to the MCMS:

    • Emergency Management

    • Rail Operations

    • Traffic Management

    • Transit Management

  3. In addition to providing feedback on the MCMS work plans, Rail Operations provides its own railroad schedules to the MCMS to inform it of planned maintenance activities of the rail network that may impact the road maintenance activities. Also, an MCMS must coordinate its work plans with maintenance organizations in adjoining geographic areas (Other MCM). This work plan coordination includes sharing work plans and providing feedback to work plans received.

  4. As a part of coordination activities, the MCMS makes requests of the Maintenance and Construction Administrative Systems (maint and constr administrative request), which would respond with information such as equipment and consumables, re-supply purchase request status, personnel qualifications including training and special certifications, environmental regulations and rules that may impact maintenance activities, and requests and project requirements from contract administration (maint and constr administrative information).

  5. To support the sequences described above, the Maintenance and Construction Center Personnel provides inputs on work plan scheduling and provides feedback to other schedules received (maint and constr center personnel inputs). They can also receive the work plans of Rail Operations or other maintenance and construction management centers (Other MCM) and can receive the feedback on work plans they have disseminated to other entities (maint and constr operations information presentation).
