ANÁLISIS DE RESULTADOS PRUEBA DE INTELIGENCIA WISC-R.

Transportation performance measures consist of a set of objective, measurable criteria used to evaluate the performance and effectiveness of the transportation system, as well as the

effectiveness of government policies, plans, and programs. Performance measures are also used to gauge the extent to which each state’s long-range transportation vision, goals, and objectives

Relationships Between Asset Chapter 5. Relationships Between Asset Management, Long- Management and Travel Demand Range Planning, Long-Range Budgeting, and Travel Demand (as described above) are being achieved. Performance measures may include such indicators as changes in travel times, transportation-related injuries and fatalities, air and water quality, number or percent of system users in various modes, fuel usage, and travel quality. While not common to all SLRPs, many state DOTs identify their current long-range plans and describe their intended application as a means of measuring the effectiveness of the long-range plan (as eventually implemented) in addressing the plans’ stated goals and objectives.

Among the sample of state DOTs selected for this study, only Caltrans and MDOT included a discussion of specific performance measures they intend to use to evaluate the effectiveness of the long-range plan (once implemented) in meeting the SLRPs’ goals and objectives. The following describes those performance measures that relate directly or indirectly to auto and track travel demand for each of these states as identified in their SLRPs. These SLRP

performance measures are consistent with the measures used elsewhere within their asset management programs.

5.6.1 California

Caltrans has worked actively with representatives of the state’s RPOs and MPOs to identify a set of consistent, multimodal, statewide performance measures. Caltrans and its statewide partners have reached consensus on a core set of performance measures. The SLRP lists the types of measures to be considered. XExhibit 5-7X is a listing of those system performance measure “indicators” that correspond to auto and/or freight travel demand-related goals, objectives, and outcomes (as identified within the SLRP).

5.6.2 Michigan

MDOT has organized the performance measures into three categories: system condition; accessibility, mobility, and safety; and operational and service performance. These categories and the individual performance measures relate either directly or indirectly to the state long- range plan. MDOT tracks more then 100 performance measures in all. The categories of

Relationships Between Asset Chapter 5. Relationships Between Asset Management, Long- Management and Travel Demand Range Planning, Long-Range Budgeting, and Travel Demand “accessibility, mobility, and safety” and “operational and service performance” relate most closely to issues of travel demand.

T

Accessibility, Mobility, and SafetyT performance refers to monitoring how frequently the transportation service is offered, how efficiently it operates, and how many crashes are taking place. For highways, it answers the question, Thow congested is the system?T Accessibility best describes the ability of people or goods to reach destinations, where mobility is the relative ease or difficulty with which the trip is made. Mobility is concerned with travel time, speeds, system usage, and system capacities. The most frequently cited performance measures relating to travel demand include:

• Level of service (A through F) • Travel delay

• Vehicle miles of travel.

These performance measures relate indirectly to MDOT’s SLRP goal of strengthening the state’s economy and directly to the goal of basic mobility.

T

Operational and ServiceT performance relates to how well the transportation system is meeting the needs of the traveling public. Key performance measures tracked by MDOT here include:

• Travel time • Travel delay • Congestion • System utilization • Facility access.

These performance measures relate directly to the SLRPs goal of transportation services coordination as an indicator of how responsive the service is to customer needs.
