TLDR
In this article, the US Environmental Protection Agency (EPA) reports improvements in each of the six air pollutants for which health-based national ambient air quality standards (NAAQS) exist, including lead, sulfur dioxide, ozone, carbon monoxide, nitrogen dioxide, and particulates.Abstract:
Significant accomplishments in air pollution emissions control have occurred over the past twenty years Emissions have been substantially reduced by both industrial and transportation sources; over the ten year period 1977-86, the US Environmental Protection Agency (EPA) reports improvements in each of the six air pollutants for which health-based national ambient air quality standards (NAAQS) exist -- lead, sulfur dioxide, ozone, carbon monoxide, nitrogen dioxide, and particulates Yet major problems remain:read more

Defining, Measuring, and Evaluating Path Walkability, and Testing Its Impacts on Transit Users’ Mode Choice and Walking Distance to the Station
TL;DR: Park et al. as mentioned in this paper conducted a factor analysis with the path walkability indicators derived from the 249 surveyed routes, and found four path-walkability factors: "sidewalk amenities", "traffic impacts", "street scale and enclosure", and "landscaping elements".

An Assessment Of Ivhs-apts Technology Impacts On Energy Consumption And Vehicle Emissions Of Transit Bus Fleets
Sylvan C Jolibois,Adib Kanafani +1 more
TL;DR: In this article, the authors examined the potential impacts of Advanced Public Transportation Systems (APTS) technologies in terms of vehicle emissions, air quality, and fuel consumption, and the results invite some skepticism about the potential benefits of APTS technologies in these areas and made recommendations regarding how program emphasis should be given to those APTs technologies and services that can attract travelers from auto to transit without increasing bus miles.

Assessing the traffic impacts of transportation and land development scenarios
Abstract: This article describes the application of a network-oriented signal timing model, TRANSYT, to evaluate development, parking, and traffic management options for an urban network. There is a growing number of cities that use TRANSYT to optimize signal timing to improve traffic operations and reduce fuel consumption. The ongoing use of the model brings additional benefits beyond those resulting from the initial updating of their timing plans. Maintenance of optimal signal timing, studies of new developments and alternative traffic and parking options appear to offer major opportunities for TRANSYT application. First, brief descriptions are given of the TRANSYT model and the study area used as a case example. Alternative policy options tested with TRANSYT are then discussed, along with results of the model application. An assessment of the study and conclusions about needed model development and refinement are presented in the last sections. 8 references, 4 figures, 4 tables.

Opportunities And Constraints For Advanced Highway Technologies: A Speculative Analysis
TL;DR: Deakin et al. as discussed by the authors presented a speculative analysis of the potential and constraints for advanced highway technologies. But they did not provide a standard, specification, or regulation for these technologies.

Telecommunications and Alternative Work Schedules: Options for Managing Transit Travel Demand
TL;DR: In this paper, the authors explore options that change the characteristics of the travel market, then trim service to accommodate the resulting, more efficient demand patterns, and suggest for collaboration between the public and private sector to stimulate and guide the use of these options.

Air quality considerations in transportation planning
TL;DR: The Clean Air Act Amendments of 1977 include provisions to correct these problems as discussed by the authors, which call for the development and implementation of plans to attain the national ambient air quality standards by 1987 under procedures that emphasize metropolitan, state, and local participation, consultation with elected officials and the public, and incremental progress in implementing transportation measures that improve air quality.
On-street parking management programs
TL;DR: In this paper, an effective on-street parking management program comprises the following major elements: regulation of onstreet parking supply; residential parking permit program; parking meter management; and programs to ensure that parking tickets are paid.

Fuel-efficient traffic signal management. three years of experience 1983-85
TL;DR: Results from three years of a statewide initiative to retime traffic signals to produce more energy-efficient traffic flow are presented, with savings of $72.3 million for California motorists and benefits of as much as $224.4 million in benefits.
