Research on public transportation systems has often focused on racialized and institutionalized dynamics that result in poor and ethno–racial minority neighborhoods being underserved. Few scholars have studied raced social interactions on the buses and trains themselves. In this article, I explore how legacies of racism are reproduced through raced social interactions on public buses and trains in Chicago. Drawing on over 3 years of ethnographic field work and interviews, this article demonstrates how ethno–racial minorities, particularly Blacks, experience racial hostilities that are often masked as nice–nastiness. Nice–nastiness is a type of individual expression that combines expressions of politeness with disdain and distancing. Nice–nastiness can be expressed as (1) pretending the “other” does not exist; (2) whispering and lowering one's voice; (3) standing instead of taking a seat; (4) letting others have space for auditory expression; and (5) pseudo–swagger. I locate nice–nastiness on the racial microaggressions and color–blindness continuum and show that this expressive tool is shaped, at least in part, by the closeness, confinement and mobility of public transportation, where escape is not possible, unlike in wide–open spaces. I use public transportation as a space to examine how raced behaviors are enacted in everyday life, and shaped by confinement and motion.

Wheel detection and axle counting systems provide the basic information for track vacancy detection, for controlling level crossing systems and a range of switching tasks or trigger functions. This technology is established throughout the world for standard gauge railways and is increasingly replacing track circuits. The requirements and the framework conditions in rail-based public transportation systems do, however, differ significantly from those in the standard-gauge railway and long distance track sectors. Nevertheless, in this segment too there is a clear trend towards wheel detection and axle counting systems. New lines and projects are increasingly being equipped with modern axle counting systems due to the benefits in terms of functionality and operating costs. Nowadays even in railed public transport systems, there is a clear move from track circuit systems to wheel detection and axle counting technology.

This paper addresses quality considerations in public transportation systems and, in particular, the relation between quality of public transport service and customer satisfaction. Its aim is to provide insights into the factors that affect transit-rider satisfaction and to present a model to calculate the probability of customer satisfaction. The proposed model identifies the most important attributes of public transport service quality that can be used for service planning.

The transmission risk of airborne diseases in public transportation systems is a concern. This paper proposes a modified Wells-Riley model for risk analysis in public transportation systems to capture the passenger flow characteristics, including spatial and temporal patterns, in the number of boarding and alighting passengers, and in number of infectors. The model is used to assess overall risk as a function of origin–destination flows, actual operations, and factors such as mask-wearing and ventilation. The model is integrated with a microscopic simulation model of subway operations (SimMETRO). Using actual data from a subway system, a case study explores the impact of different factors on transmission risk, including mask-wearing, ventilation rates, infectiousness levels of disease, and carrier rates. In general, mask-wearing and ventilation are effective under various demand levels, infectiousness levels, and carrier rates. Mask-wearing is more effective in mitigating risks. Impacts from operations and service frequency are also evaluated, emphasizing the importance of maintaining reliable, frequent operations in lowering transmission risks. Risk spatial patterns are also explored, highlighting locations of higher risk.
