Climate change is intensifying coastal floods and increasing the risks of traffic disruption in low-lying, coastal communities. Efforts to understand the differential impacts of traffic disruption on communities have led to the concept of traffic resilience which captures the degree to which a traffic system can recover from disruption. Existing proxies of traffic resilience are focused on quantifying travel time delays but lack the important dimension of road safety. In this study, we quantify traffic resilience in terms of the change in non-highway car and pedestrian accident rates during the 5-10 am period as a result of coastal flooding in the San Francisco Bay Area for the 2020-2040 period. We use a regional traffic model to simulate traffic patterns under a range of coastal flood water levels. We use regressions that relate traffic volumes to historical accident rates to estimate accidents rates in the presence of flooding. Our results show that the flooding of highways forces commuters onto local roads passing through residential communities, causing a spike in accident rates. Unlike delays which increase sharply at the higher water levels considered in this study, we project that region-wide peak-hour accident rates may increase substantially at lower water levels.

Researchers and practitioners have much to learn from drag queens, specifically Latinx queens, as they leverage everyday queerness and brownness in ways that contribute to pedagogy locally and globally, individually and collectively. Drawing on previous work examining the digital queer gestures of drag queen educators (Lizárraga & Cortez, 2019), this essay explores how non-dominant people that exist and fluctuate in the in-between of boundaries of gender, race, sexuality, the physical, and the virtual provide pedagogical overtures for imagining and organizing for new possible futures that are equitable and just. Further animated by Donna Haraway’s (2006) influential feminist post-humanist work, we interrogate how Latinx drag queens as cyborgs use digital technologies to enhance their craft and engage in powerful pedagogical moves. This essay draws from robust analyses of the digital presence of and interviews with two Latinx drag queens in the San Francisco Bay Area, as well as the online presence of a Xicanx doggie drag queen named RuPawl. Our participants actively drew on their liminality to provoke and mobilize communities around socio-political issues. In this regard, we see them engaging in transformative public cyborg jotería pedagogies that are made visible and historicized in the digital and physical world.

Traversing the kaleidoscope of memory of early adulthood in the San Francisco bay area, David Ulin describes the places as he remembers them with picturesque account: Andrew Molera State Park, Fort Mason, Marin Headlands, Old Waldorf, and Sutro Tower, with the particulars, and what happened to his experience of time in those places that summer of 1980. Experienced as a series of fleeting memories, joining together with others who lived there for a time. They left, and so did the author, experiencing the power of temporality or “abandon” both in and from this place.

The San Francisco Bay area is facing a mounting problem of handling the ever-increasing flow of traffic. With this traffic rising so rapidly in an area severely constricted by topography it has been concluded that freeway, bridge, and parking improvements alone cannot meet the Bay area's mounting transportation needs. Rapid transit, utilizing only a fraction of the space and with much less cost, would provide far more passenger capacity than automobiles on freeway and as a result a billion dollar rapid transit system has been planned for the Bay area. This paper describes the design and development of the BARTD system at present being undertaken.
