Project Summary

Many regions in California have prepared long-term plans for goods movement, recognizing the need to develop freight facilities to accommodate the transformation and growth of logistics in the state. Yet, for most, planning for industrial lands – and related jobs –is an afterthought. The Metropolitan Planning Commission and the Association of Bay Area Governments (ABAG) have thus decided to enact a new program that allows jurisdictions to prioritize industrial uses (the Priority Production Areas or PPAs). PPAs will then be included in the region’s Sustainable Communities Strategies. Although ABAG’s Executive Board adopted the program in early 2017, and it is mentioned in the 2040 Plan Bay Area, the program has not yet been developed. This translational project will help the Bay Area’s regional agencies develop the program. Building on program guidelines suggested by the recent “Goods Movement and Industrial Land Supply” study (funded by Caltrans), this project will interview and convene UC, regional agency, local jurisdiction staff, and economic development organizations to discuss and develop potential guidelines for designating PPAs. UC-Berkeley will also assist by identifying possible incentives and other implementation mechanisms and providing data and analysis to assist jurisdictions interested in participating in the program.

Encouraging Mode Shift from Truck to Rail for California Produce

Project Summary

The movement of California goods is one of the largest employment generators within the state and is critical to both the structural health of the economy and the physical health of its citizens. However, the goods movement sector is subject to market failures that may result in suboptimal modal shares, in particular an excess of truck traffic some of which would ideally be diverted to rail. While opportunities for modal shift are limited within the state, there are significant possibilities for California exports. Examining the agricultural sector, California is one of the largest producers of perishable produce in the world and a majority of this produce leaves the state on a truck, despite the fact that rail dominated the market through the mid-1970’s. Significant inertia exists today among the grower-shipper- buyer network that has frozen in place the domination of the trucking industry among perishable produce, even though rail movement would reduce social cost in many cases. While the private sector is unlikely to invest in a modal shift given the historically low fuel prices, it is possible that there is an opening for a public-private partnership (PPP) that could provide a gentle push for change. This project will build on the initial work from the “Rail and the California Economy” project and explore the possibility of using public initiatives—including capital investment, risk sharing, subsidy, and other interventions—to support new rail infrastructure for the perishable produce industry. Specifically, the report will review the current state of affairs in two major growing regions, the Salinas Valley and the southern Central Valley, and analyze how goods move and the benefits of a modal shift to rail. The report will then identify public-private partnerships that might promote a shift to realize these benefits. Additionally, if time permits the project may review an existing PPP involving rail, the reconstruction of the Colton Crossing in southern California and the public benefits associated with its completion.

Project Summary

Southern California is no stranger to auto-related pollution. Areas near roadways typically demonstrate much higher pollutant concentrations; as a result, pedestrians and residents in these areas face greater exposure to air pollutants. In dense urban areas like Los Angeles, near-roadway environments can include most street-level outdoor spaces. At the same time, traffic-related pollution levels in urban areas are highly variable. Although the connection between built environment and street-level pollutant concentrations is a nascent field of study, it is clear that the design of the built environment plays a major role on pollution concentration.

The researchers examined the effects of different built environment designs on the concentrations of street-level ultrafine particles (UFP) at the scale of several blocks using the Quick Urban and Industrial Complex (QUIC) numerical modeling system. They evaluated the effects of several built environment designs, changing building heights and spacing while holding total built environment volumes constant. They found that ground-level open space reduces street-level pollutant concentrations. Holding volume/surface area constant, tall buildings clustered together with larger open spaces between buildings resulted in substantially lower pollutant concentrations than buildings in rows. Buildings arranged on a ‘checkerboard’ grid with smaller contiguous open spaces, a configuration with some open space on one of the sides of the roadway at all locations, resulted in the lowest average concentrations for almost all wind directions. Rows usually prohibit mixing for perpendicular and oblique wind directions, even when there are large spaces between them, and clustered buildings have some areas where buildings border both sides of the roadways, inhibiting mixing. The model results suggest that pollutant concentrations drop off rapidly with height in the first 10 m or so above the roadways. In addition, the simulated vertical concentration profiles show a moderate elevated peak at the roof levels of the shorter buildings within the area. Model limitations and suggestions both for urban design are both discussed.

Examining Both Trip Level Mode Replacements and Daily Activity Patterns of Users is Required to Understand the Sustainability Potential of Micromobility

Abstract

Micromobility options such as electric bike-share and scooter-share services are a fundamental part of the existing shared mobility landscape. Research has shown that micromobility use can reduce car dependence. This is accomplished through trip-level mode replacement and adjustments in mode-use configurations in daily travel. Understanding the full potential of micromobility services as a car replacement can help cities better plan for the services to meet environmental sustainability goals. Researchers at the University of California, Davis collected GPS-based travel diary data from individual micromobility users from 48 cities in the US and examined their travel behavior and micromobility use patterns. They found that micromobility services can displace car use. To achieve environmental sustainability goals, cities must pursue options that will deliver benefits, such as micromobility services. This policy brief summarizes the findings from that research and provides policy implications.
