This paper describes a before-and-after case study of a protected intersection in Salt Lake City, Utah. The intersection was completed in late 2015 and represented one of the first examples of a protected intersection design in North America. We analyzed bird’s-eye view video data that was recorded before the intersection was implemented and compared it against video data recorded from the exact same location after implementation. In order to examine changes in intersection usage and behavior, we operationalized safety in terms of the frequency of nonoptimal behaviors demonstrated by active transportation modes. We found that active transportation usage of the intersection has increased since the new configuration, with most of that growth attributable to e-scooter users. There was minimal change in the rates of nonoptimal behaviors by pedestrians. Bicyclists showed mostly decreased rates of nonoptimal behaviors, suggesting improved safety for this mode. E-scooter users, however, demonstrated nonoptimal behaviors at very high rates as compared with other active modes. This case study gives evidence that a protected intersection can have positive effects on active transportation volume and safety in a U.S. context.

Abstract Since its fiftieth anniversary, memorialization of the Korean War has taken place in towns and cities across the United States. As a case study of this belated memory boom, this essay looks at the Utah Korean War Memorial, erected by local veterans in 2003 at Memory Grove Park, Salt Lake City. Situated in both the local and national contexts of remembrance, the memorial resonates largely with three mythical scripts, with themes of resilience, local pride, and the good war, all of which have allowed veterans to negotiate tensions between individual and collective memories. This case study reveals in particular how the official commemoration of the war has shifted local veterans' rhetorical positions from potential witnesses of subversive realities of the war to uncritical negotiators whose legitimization of the very process of mythologizing memories has ultimately alienated them from their own experiences during and after the war.

This article explores concepts related to connectivity and usership of the Jordan River Parkway Trail (JRPT) and the North Temple corridor—two locations or nodes that link together in a larger transportation network along the west side of Salt Lake City, Utah, a low-income, racially and ethnically diverse area. The JRPT is a multi-use trail providing regional connectivity for bicycles and pedestrians. It intersects North Temple, a transit development corridor accommodating automobiles, light rail, buses, bicycles, and pedestrians. Although the purposes of each corridor differ, one being recreational and one being commercial, the modes of transportation for each corridor overlap through active transportation—that is, biking and walking. The questions that drive this paper are: (1) How are these two neighborhood assets are connected and form a larger transportation network? and, (2) How can connectivity and usership be improved? The idea of increasing the utilization of the JRPT through increasing destinations along North Temple and vice versa is explored. Community feedback was gathered through a survey which was distributed to 299 residents who live less than a mile from each subnetwork. Extracted from the responses were key aspects of connectivity, accessibility, and the purposes of each corridor for the community as a whole to understand how they are connected and how they affect each other. More broadly, urban policy recommendations that increase active transportation connectivity and usership of two sets of links—that is, regional trails and transit-oriented corridors such as the JRPT and the North Temple corridor are described.

Background:Complete streets require evaluation to determine if they encourage active transportation.Methods:Data were collected before and after a street intervention provided new light rail, bike lanes, and better sidewalks in Salt Lake City, Utah. Residents living near (<800 m) and far (≥801 to 2000 m) from the street were compared, with sensitivity tests for alternative definitions of near (<600 and <1000 m). Dependent variables were accelerometer/global positioning system (GPS) measures of transit trips, nontransit walking trips, and biking trips that included the complete street corridor.Results:Active travel trips for Near-Time 2 residents, the group hypothesized to be the most active, were compared with the other 3 groups (Near-Time 1, Far-Time 1, and Far-Time 2), net of control variables. Near-Time 2 residents were more likely to engage in complete street transit walking trips (35%, adjusted) and nontransit walking trips (50%) than the other 3 groups (24% to 25% and 13% to 36%, respectively). Bicycling was less prevalent, with only 1 of 3 contrasts significant (10% of Near-Time 2 residents had complete street bicycle trips compared with 5% of Far-Time 1 residents).Conclusions:Living near the complete street intervention supported more pedestrian use and possibly bicycling, suggesting complete streets are also public health interventions.

Transit-oriented developments are touted as providing a variety of social benefits, but personal benefits to residents are underresearched. The authors surveyed 51 residents before and after a new light rail stop was constructed in their revitalizing Salt Lake City neighborhood. Residents anticipated and then later experienced increased housing and neighborhood economic values, enhanced sense of community, and improved neighborhood reputation. Residents experienced greater than anticipated pedestrian and child safety after rail service started. Compared with resident perceptions of walkable neighborhoods elsewhere, the Salt Lake residents perceived their neighborhood to be denser, and offering less land-use diversity and more crime safety problems. Perceived walkability increased, with residents reporting greater land-use diversity and neighborhood satisfaction after rail stop completion. However, residents said more stores, parks and trails, and trees would improve walkability. These results show the personal benefits residents desire to make transit-oriented living a satisfying residential alternative.

AbstractWriting in Nationalist revolutionaries in Ireland, 1858–1928, Tom Garvin observed that ‘well over 40 per cent, perhaps 50 per cent, had lived outside Ireland for considerable periods … foreign experience was very important in the development of the leaders’. The impact of ‘foreign experience’ on leading nationalist revolutionaries, this article submits, pace Garvin, could have proved influential in the development of the Irish Revolution more widely. Between June 1919 and December 1920, Éamon de Valera toured the United States. From New York City to Salt Lake City, Alabama to Montana, the self-proclaimed president of the Irish republic addressed ‘Ireland’ in hundreds of interviews and speeches. Of these myriad public statements, his Cuban missive, notably, crossed national boundaries. Comparing Ireland's geo-strategic relationship with Great Britain to that of Cuba and the United States, de Valera's argument for an independent Irish republic was made in the Americas. How did de Valera's movement across the U.S. alter his political views of Ireland? How were presentations of de Valera's ‘Cuban policy’ mediated across the ‘Irish world’? How did discourse on the Monroe Doctrine inform Anglo-Irish negotiations between Truce and Treaty? Exploring de Valera's ‘Cuban policy’ as global case study, this article concludes, ultimately, can shift the historiographical significance of ‘foreign experience’ from nationalist revolutionaries in Ireland to the flows and circulation of transnational revolution.
