The Public

As in many cities, congestion in Washington, D.C., is one of the top concerns of residents, businesses, travelers, and policy makers. Monitoring and communicating system performance from a mobility perspective is challenging, particularly when dealing with the multimodal nature of travel in urban areas. The District Department of Transportation has identified a set of performance measures for multimodal mobility—including congestion—that are based on available data and is making these metrics available to the public and to policy makers through an innovative visualization tool. The study’s approach, measures, and visualization component provide a model for other jurisdictions to consider adopting when seeking to better understand and convey the challenges, opportunities, and interdependencies of multimodal travel.

Transportation Plan

A proposed set of aviation system performance measures that have been defined to support multimodal transportation planning in California is presented. As part of the 1998 update of the California Transportation Plan (CTP), the California Department of Transportation has defined a framework of system performance measures that could be applied on a multimodal basis to assess the performance of the transportation system, support informed decision making, and establish a coordinated and consistent process for performance measurement throughout the state. The research that is described examined approaches to measuring the performance of the aviation system that have been adopted at a national level and in other states, as well as general principles for measurement of transportation system performance that emerged from a conference held in 1997 as part of the CTP update process. The range of considerations that arise in measuring the performance of the aviation system is discussed, and potential performance measures that have been proposed to address the requirements of the CTP framework are identified. Finally, issues that will need to be addressed in implementing any comprehensive set of performance measures for the aviation component of the transportation system are discussed.

Multimodal Systems

Transportation systems analyses have been evolving as the decision context for improvement projects and programs has changed. The increased emphasis on the movement of persons and goods, and a recognition of the importance of system performance measures that address the needs and interests of the audiences for mobility information, will result in a very different set of procedures for evaluating transportation and land use infrastructure and policies. Some of the key underlying concerns of performance measurement for multimodal systems are presented. Definitions are included for congestion, mobility, and accessibility that are used to guide the development of performance measures. Travel time–based measures are seen as the most readily understandable quantities, and examples are used to show how mobility can be measured for locations, corridors, transit analyses, and regional networks.

The purpose of this study is to investigate the performance management measures related to highway system reliability, freight, and traffic congestion in light of the federal rulemaking that establishes these performance measures. The study conducts an exploratory analysis to understand their inter-relationships and examines their (un)common underlying attributes to discover their associativity with each of the performance measures. In doing so several traffic and roadway related characteristics of each reporting segment of the National Highway System (NHS) of South Carolina were processed and modeled for the travel time reliability and peak hour excessive delay using generalized linear models with a log-link function. The results from the study indicate that the unreliable Interstate segments contributed to about 87% of the excessive delays on the entire Interstate. It was also found that more than half of the non-Interstate NHS segments that experienced excessive delay, were reliable and they contributed to approximately 52% of the entire peak hour excessive delay of the non-Interstate NHS. The results from the model indicate that the directional annual average daily traffic (AADT) and the urban areas are the two most important attributes positively associated with all three performance measures, while the number of through lanes was found to be negatively associated with all three performance measures. The length of the reporting segments was positively associated with the excessive delays but negatively associated with the travel time reliabilities. The percentage of single trucks was unique to the Interstate delays and positively associated.

The Impact

Linking urban development and urban drainage models is a more and more popular approach when impacts of pavement of urban areas on sewer system performance are evaluated. As such an approach is a difficult task, this is not a feasible procedure for everyday engineering practice. We propose an alternative method, based on a developed simple near-quadratic relationship, which directly translates change (increase or decrease) of paved area into a change in the return period (RP) of the design rainfall event or design rainfall intensity. This formula is simple to use and compatible with existing design guidelines. A further advantage is that the calculated design RP can also be used to communicate the impact of a change in impervious areas to stakeholders or the public community. The method is developed using a set of 250 virtual and two real-world case studies and hydrodynamic simulations. It is validated on a small catchment for which we compare system performance and redesigned pipe diameters. Of course such a simplification contains different uncertainties. But these uncertainties have to be seen in the context of overall uncertainties when trying to predict city development into the future. Hence it still is a significant advantage compared to today's engineering practice.

Regional Problems

In December 1993 Secretary of Transportation Federico Peña called for the creation of a National Transportation System (NTS). The goal of the NTS is to support national transportation planning and policy that maximize the efficiency and effectiveness of the nation's transportation network, in accordance with the mission of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA). It is proposed that the U.S. Department of Transportation (DOT) pursue this goal by designing an NTS that can monitor the performance of the nation's transportation network; detect national and regional problems with the transportation system; facilitate the setting of performance goals and measure progress over time; and aid states and metropolitan areas in performance-based planning. To do this, the NTS must evaluate the transportation network's performance in terms of moving passengers and goods and of achieving the goals of the system's users. Therefore, the NTS must have as its basis a set of performance measures that apply to different modes and that reflect the varied goals of ISTEA, in the areas of system output as well as the environmental, social, and economic outcomes of system usage. Such performance measures are proposed, as is a general decision-making framework for using them. The ISTEA legislation, the NTS initiative, and potential data sources for supporting these performance measures are also examined.

Data Driven Approach

In the ongoing challenge to balance competing demands for curb space in dense urban areas, pricing has become an increasingly popular tool for better matching supply and demand. Performance parking, which applies variable pricing to parking, relies on performance metrics from responsive data and technology to manage pricing and occupancy or availability of parking. However, as parking managers and policy makers have embraced a more data-driven approach to price setting, they have not applied the same objectivity to the delineation of where performance parking should be implemented. The District of Columbia Department of Transportation is faced with the problem of where to apply performance parking appropriately. Initially, performance parking zones were legislatively designated, but in 2012, the enabling legislation was expanded to allow application citywide. Embracing the fact that performance parking is driven by objective metrics, the department developed a methodology to identify and define the objective efficacy of subareas to possibly implement performance parking. The background of the performance parking program is described and shows how the program goals were used to define several metrics for analyzing potential performance parking subareas. The analysis identified 10 potential subareas prime for implementation of performance-based curbside management pricing. This analysis provides an approach to establish the objective justification for the use of performance pricing within subareas of the District. As a result, the District of Columbia Department of Transportation can articulate why certain areas are selected and can implement performance parking with a higher level of confidence that the program will produce the intended impacts.

Definition Of

Growth trends in Minnesota emphasize the need to ensure that travel on highway corridors linking regional trade centers in the state is safe, reliable, and efficient. In 1999, the Minnesota Department of Transportation initiated an interregional corridor study to define a system of interregional corridors that connect important regional trade centers. Minnesota’s effort to develop the interregional corridor system, performance expectations, and principles and policies for managing and guiding development along these corridors is described. The interregional corridor system and the corresponding management principles and policies were developed in several phases: ( a) definition of regional trade centers, ( b) identification of the interregional corridor system, ( c) development of interregional corridor principles and policies, and ( d) development of a corridor management plan guide. The study developed performance measures and performance targets to identify mobility risk corridors, which are corridors that perform below target speed or have a risk of signal proliferation. Methods used at a sketch-planning level to identify priority routes and performance levels are described. The study developed a more uniform process for developing corridor management plans.

Highly Correlated

The objective of this study is to quantify the correlation between nearly 100 external factors and over 70 performance measures of the Florida multimodal transportation system, based on the empirical data covering a 10 year period (2009–2018). We first use time-lagged cross-correlation to quantify the correlation between each pair of external factors and performance measures. We then identify the highly correlated external factors with all performance measures or a subset of them. We find that Percentage of Population in Poverty (Florida), Number of Housing Units (Florida), House Price Index (National), Consumer Price Index–Rent Price Index (Florida), and Percentage of Population in Poverty (National) are the external factors highly correlated with the whole system, while the external factors highly correlated with different modes vary. This paper thus contributes to the transportation performance measurement literature by proposing a practical procedure based on time series analysis to help transportation agencies identify important external factors for tracking and monitoring.
