Transportation barriers are often the reason for the discrepancy in the employment rate between people with disabilities and others, yet little information about the transportation barriers and the needs of people with disabilities who are searching for employment is available. The primary objective of this paper is to share valuable information from a unique survey of people with disabilities who were actively searching for employment in New Jersey. The paper examines the role of public transportation in providing job access to people with disabilities and provides information and insights on the availability, use, needs, barriers, and perceptions of the survey respondents about different public transit modes. The paper also discusses the implications for agencies that provide transportation for people with human services needs. Research shows that despite the frequent use of public transportation by job-seeking people with disabilities, many of them are dissatisfied with public transportation. Although satisfaction with vehicle equipment compliant with the Americans with Disabilities Act seems high, many individuals are dissatisfied with the level of transit service and environmental barriers between homes and transit stations and stops. It can be inferred from the results that a multitude of strategies will be needed to address the travel needs and barriers of job-seeking people with disabilities in the state. In addition to providing assistance with transportation for people with human services needs and providing insights to vocational rehabilitation counselors, the study will serve as a means for laying the framework for more rigorous research on the transportation needs and barriers of people with disabilities.

Although autism spectrum disorder (ASD) has received a substantial amount of attention in other fields, very little appears in the transportation literature about people with ASD. Because the National Household Travel Survey and metropolitan travel surveys do not classify people with ASD as a separate category of persons with disabilities, very little information is available about their travel patterns, needs, or barriers. To bridge the existing information gap, this paper provides results from a recent survey that focused exclusively on adults with ASD in New Jersey to learn about their travel patterns, the importance of the various types of trips they make, and the barriers they encounter regarding the use of different transportation modes. The survey, distributed through various organizations throughout the state, was completed by or for 703 adults. Because the objective of the paper is to provide as much information as possible from the survey, no attempt has been made to compare the travel patterns, needs, and barriers of the survey respondents with those of the general population. However, other researchers can easily compare the survey results provided in this paper with data from other sources. Although the survey generated other valuable information, the most revealing information pertained to barriers to walking, driving, taking public transit, and even taking rides from others. The information collected through this research is being shared through outreach efforts with agencies that provide or fund transportation to persons with disabilities in New Jersey.

Predictions in recent studies that an increasingly large number of households will locate near rail stations because of changing lifestyles and perceptions of younger generations should be a reason for concern for transportation planners as excessively high demand for housing near stations can displace disadvantaged populations. In New Jersey, where the statewide Transit Village programme was introduced in 1999 to promote transit-oriented developments (TOD), many communities with rail stations are currently inhabited by low-income and minority populations. While gentrification through TODs can have many environmental and economic benefits, caution is needed to ensure that it does not displace disadvantaged households. With this assertion, the study sets benchmarks for current population characteristics of the areas near commuter rail stations in New Jersey and compares changes of the characteristics between 1990 and 2013 by using the Geolytics Neighborhood Change Database. Specifically, it compares the socioeconomic characteristics of the areas near stations with the areas further both at the macro and the micro levels by focusing on race, ethnicity, income, rent and other key variables. The study uses analysis of variance and regression models to compare areas near stations with areas beyond. Although the regression models showed higher home value and greater increase in home value near stations than areas further, change in rent has been more stable. The analysis did not reveal significant undesirable changes in population characteristics in the areas near stations, especially for the variables on race and ethnicity.

The recent increases in auto ownership among low-income households make one wonder whether public transit continues to provide adequate services to this group of transportation disadvantaged. With this question in mind, the study examines the relationship between transit availability and auto ownership with travel survey data from Los Angeles. Although the relationship is statistically significant, it is rather weak, indicating that significant improvements will be needed in transit services to bring forth a slight decrease in auto ownership among the general population. Empirical evidence also shows that auto ownership is relatively low among the poorest households. Due to the difficulties in attracting the general population from automobile use to transit use, it has been suggested that instead of trying to achieve its many objectives, transit may benefit by rigorously pursuing provision of services to those incapable of owning and operating an automobile.
