United States fatal pedestrian crash hot spot locations and
characteristics
- Authors: Robert James Schneider, Rebecca Sanders, Frank Proulx, Hamideh Moayyed
  Pages: 1 - 23
  Abstract: US pedestrian fatalities are at their highest level in nearly three decades and account for an increasing share of total traffic fatalities (16%). To achieve the vision of a future transportation system that produces zero deaths, pedestrian safety must be improved. In this study, we screened the entire US roadway network to identify fatal pedestrian crash “hot spot” corridors: 1,000-meter-long sections of roadway where six or more fatal pedestrian crashes occurred during an eightyear period. We identified 34 hot spot corridors during 2001-2008 and 31 during 2009-2016. While only five corridors were hot spots during both analysis periods, the 60 unique hot spots had remarkably consistent characteristics. Nearly all (97%) were multilane roadways, with 70% requiring pedestrians to cross five or more lanes. More than three-quarters had speed limits of 30 mph or higher, and 62% had traffic volumes exceeding 25,000 vehicles per day. All had adjacent commercial retail and service land uses, 72% had billboards, and three-quarters were bordered by low-income neighborhoods. Corridors with these characteristics clearly have the potential to produce high numbers of pedestrian fatalities. We also used hierarchical clustering to classify the hot spots based on their roadway and surrounding landuse characteristics into three types: regional highways, urban primary arterial roadways, and New York City thoroughfares. Each context may require different safety strategies. Our results support a systemic approach to improve pedestrian safety: Agencies should identify other roadway corridors with similar characteristics throughout the US and take actions to reduce the risk of future pedestrian fatalities.

Identification of the geographical extent of an area benefiting from a
transportation project: A generalized synthetic control
- Authors: Takara Kunimi, Hajime Seya
  Pages: 25 - 45
  Abstract: In evaluating the benefits of an infrastructure project, it is essential to consider who is benefiting from the project and where benefits are located. However, there is no established way to accurately determine the latter. To fill this methodological gap, this study proposes an approach for the ex-post identification of the geographical extent of an area benefiting from a transportation project based on a generalized synthetic control method. Specifically, it allows comparing multiple treatment units with their counterfactuals in a single run—changes in land prices (actual outcome) at each treated site are compared to the counterfactual outcome, and the individual (i.e., unit-level) treatment effect on the treated site is then estimated. This approach is empirically applied to a large-scale Japanese heavy railway, the Tsukuba Express line project. Our approach enables the detection of 1) the complicated spatial shape of benefit incidence; 2) negative spillovers; and 3) the increase in options (train routes), typically not considered in a benefit evaluation system based on the hedonic approach, but which can be capitalized into land prices.

Driving change: Exploring the adoption of multimodal local traffic impact
assessment practices
- Authors: Tabitha Combs, Noreen McDonald
  Pages: 47 - 64
  Abstract: Local governments in the US face growing public demands to reduce automobile dependence in order to forestall climate change, improve road safety, rein in sprawling peripheral land development, increase transportation equity, and enhance urban livability. As a result, many city and county leaders are looking for ways to provide alternatives to driving through the creation of more multimodal-supportive transportation systems and land use patterns. The academic literature has identified conventional traffic impact- assessment (TIA) practices—designed to ensure new developments do not increase automobile traffic congestion—as a barrier to supporting these multimodal efforts. Because of the growing emphasis on multimodality in many national, state, and regional policies and initiatives (e.g., Complete Streets, Vision Zero), we investigate whether and how communities were adapting TIA practices to better accommodate pedestrians, bicyclists, transit users, and other non-car travel modes in the land development process.

An integrated land-use/transportation forecasting and planning model: A
metropolitan planning support system
- Authors: Ardeshir Anjomani
  Pages: 65 - 86
  Abstract: Over the last several decades, land-use/transport interaction models have evolved. Although these models have the potential to become primary demographic forecasting and planning vehicles in metropolitan transportation planning for most large US urban regions, some gaps and improvements must be addressed. This paper briefly discusses a newly developed and refined integrated land-use/transportation model. It also introduces innovative approaches to modeling an urban area including a variant of a geographic information system-based land-use and environmental suitability analysis, as main components in deriving development potential for a small-cell grid of the study region. This approach enables the inclusion of public and stakeholder input into the modeling process, facilitates micro-level consideration of trip generation, trip distribution, and mode-choice inside the land-use demographic model, thus furthering the integration of transportation and land use in the modeling process. Such considerations and utilization of rule-based approaches and concerns of economic development and environmental and sustainability factors help close some existing gaps of operational models designed for real world practical applications. All of these features contribute toward further improvement of these models.

Borrowed sizes: A hedonic price approach to the value of netowrk structure
in public transport systems
- Authors: Helena Bohman, Désirée Nilsson
  Pages: 87 - 103
  Abstract: Property prices are known to be higher in places with high accessibility, such as in proximity to train stations and especially to commuter rail, than in places without this access. This study provides a better understanding of how regional accessibility, through the structure of railway networks, can influence local agglomeration economies by providing accessibility to large labor markets. Previous literature has shown a positive impact of proximity to railway stations on housing prices, and our study adds to the literature by analyzing the impact of network structure. We argue that public transport systems can support the benefits of city networks in line with Alonso’s concept of borrowed sizes (1973). Using network theory to measure accessibility provided by the network, we show that stations that provide accessibility to large labor markets across the region are perceived as more attractive by households. Cities in proximity to other cities are strengthened through their public transport links, which allow agglomeration benefits to be exploited by residents.

Car ownership and commuting mode of the “original” residents in a
high-density city center: A case study in Shanghai
- Authors: Tao Chen, Haixiao Pan, Yanbo Ge
  Pages: 105 - 124
  Abstract: As a result of rapid urbanization and motorization in China, numerous mega-cities have emerged, and large numbers of people live and work in the city centers. Consequently, developing a public transport-oriented urban structure and promoting sustainable development are major planning strategies for the country. To understand the impact of rail transit on motorization in a high-density city center, we conduct a household travel survey in three neighborhoods around metro stations in the central area of Shanghai. We examine the car buying and commuting behavior of those Shanghai “original” residents who lived there when the city began growing, engulfing them in the center. Studies have shown that 40 percent of commuters in the city center commute outward, following a virtually reversed commute pattern, and the factors significantly affecting their car purchasing choice include their attitude toward cars and transit, household incomes, ownership of the apartments they live in, and the distance between family members’ workplaces and nearest metro stations. Despite easy access to the metro from their home in the city center, those who purchase their apartment units also likely own a car, while those who rent their apartment units are less likely to own a car; however, these odds are still higher than for those who live in an apartment unit inherited from their relatives or provided by their company. In the city center, if a family owns a car, then that car would almost certainly be used for daily commuting. A multinomial logistic model is applied to examine the factors influencing the tendency for using cars. The results show that people’s choices of commuting by alternative modes rather than cars are also shaped by their attitude toward public transportation, but other factors can also subtly change people’s commuting behavior under certain conditions. The commuting distance discourages people from walking and taking buses (but not metro). As the egress distance to the workplace increases, the metro becomes less appealing than cars. Mixed land use encourages people to walk or take buses instead of driving. Older people prefer riding buses and walking to driving, and female respondents tend to prefer walking, cycling, and riding the metro to driving compared to male respondents. These findings contribute to understanding the behavior of people who are familiar with public transportation and how to encourage them to switch from driving cars to alternative transport modes.
