Land Use Challenges to Implementing Transit-Oriented Development in China: Case Study of Jinan, Shandong Province

Several Chinese cities are interested in incorporating transit-oriented development (TOD) around their subway stations. Few cities, however, have considered incorporating TOD into their bus systems; fewer still have included China's bike population. The midsize Chinese city of Jinan, capital of the northeastern province of Shandong, wants to incorporate both bus rapid transit (BRT) and TOD within its urban planning framework. Jinan is set to construct a 135-km BRT network and seeks to incorporate TOD initially at the neighborhood level and eventually in the entire city. As part of an...

Drivability vs. Walkability: Assessing Shorter- and Longer-Term Transportation Planning Tradeoffs in a Chinese Context

This paper describes how cities in developing countries often invest large sums to build highways and arterials serving a rapidly growing number of automobiles. Although highway investments are a priority, walking remains the most common mode of transport and buses (or motorbikes) the most common form of motor vehicle in use. The wide new arterials deliver short-term employment and construction spending benefits and in the longer term can contribute to increased productivity. On the other hand, their design and operation can reduce accessibility for pedestrians, bicyclists, and transit...

Climate Change and Urban Transportation in Latin America: Analysis of Recent Projects

Urban transportation investments present an opportunity to mitigate climate change while supporting effective, clean, safe, and equitable transportation. This study reports on the response of a set of urban transportation investments in Latin America to climate change. A sample of recent transportation projects funded by an international bank was analyzed to learn what kinds of infrastructure, plans, and policies were being pursued and to assess whether projects developed specifically to address climate change differed from other projects. Loans and grants supported a mix of infrastructure...

Women and Cycling: A Case Study of the Use of San Francisco Bike Lanes

This paper presents a case study of the use of San Francisco bike lanes with a focus on women. Bike counts and intercept surveys of cyclists at three locations in San Francisco’s SoMa District were complemented by focus groups with cyclists, particularly women cyclists, and brief interviews with non-cyclists. Consistent with other US studies, we find that white men are disproportionately represented among the cyclists we observed, and that women bike less and bike shorter distances. However, at least in the SoMa sample, women are more likely to bike to work than men. Cyclists included...

UAV Scheduling Strategies in Multi-modal Last-Mile Urban Parcel Delivery

Urban parcel delivery has emerged as a high growth market, and the resulting delivery traffic can pose great challenges in dense urban areas. There is growing interest in supplanting the conventional model of a dedicated delivery person operating a van to alternatives featuring new classes of vehicles such as drones, autonomous ground vehicles, cargo bikes and non-motorized vehicles. This work proposes combined delivery strategies using trucks, cargo bikes and drones. We develop and compare multi-modal delivery strategies with various mode combinations. We work on zone-based multi-modal...

Pilot Models for Estimating Bicycle Intersection Volumes

Schneider, Robert J.
2011

Bicycle volume data are useful to practitioners and researchers to understand safety, travel behavior, and development impacts. This paper describes the methodology used to develop several simple models of bicycle intersection volumes in Alameda County, California. The models are based on two-hour bicycle counts performed at a sample of 81 intersections in the Spring of 2008 and 2009. Study sites represented areas with a wide range of population density, employment density, proximity to commercial property, neighborhood income, and street network characteristics. The explanatory variables...

Old Road, New Directions: Plan for Adeline Street in Berkeley, California

2011

This paper presents a plan for transforming a major arterial and a transit station that divide a low-income business and residential district into an economically healthy, context-sensitive, transit-oriented development. Adeline Street is a major point of entry into Berkeley, California, linking the city of Oakland on the south to the central districts of Berkeley. Formerly a major streetcar corridor, Adeline is now the location of a Bay Area Rapid Transit (BART) station and a surface parking lot, for which housing and businesses were removed in the 1960s. The street's 180-ft right-of-way...

Bicycle level of service (LOS) measures are essential tools for transportation agencies to monitor and prioritize improvements to infrastructure for cyclists. While it is apparent that different types of cyclists have varying preferences for the facilities on which they ride, in current research and practice, measures are used that are either insufficiently quantitative and empirical or lack cyclist segmentation. In this study, we conducted a detailed survey on cyclist habits, preferences, and user experience, capturing responses to videos of a bicycle traveling on road segments in the San...

Caltrans is considering performance measures that can be used to evaluate the quality of the bicycling experience on the state highway system. The purpose of this research is to recommend the best methodology to use in California as a quantitative measurement for how well the roads support bicycling. We identified two widely used performance measures, Highway Capacity Manual bicycle level of service and level of traffic stress, for evaluation, and developed time cost estimates for applying the measures to the state highway system. In addition, we performed a pilot study to test a proof of...

Developing quality California-specific crash modification factors (CMFs) for bicycle-related safety countermeasures will support practitioners in making more informed decisions about infrastructure improvement projects. The researchers identified a comprehensive list of countermeasures, identified existing CMFs and reviewed their quality and applicability to California, determined key bicycle injury and fatality crash patterns in the state, prioritized potential bicycle safety countermeasures for study, and identified potential study sites. The results show there is limited availability of...
