Blog: Improving Pedestrian Safety in Hawaiʻi
By Justin Tyndall Over 2,500 people have been killed in motor vehicle crashes in Hawaiʻi since 2000, averaging a person every three days. Car crashes are a leading cause of accidental death, particularly for younger people. In a different setting, this scale of mortality might be treated as a public health emergency, but we have […]
Read MoreThe local labour market effects of light rail transit
Many US cities have made large investments in light rail transit in order to improve commuting networks. I analyse the labour market effects of light rail in four US metros. I propose a new instrumental variable to overcome endogeneity in transit station location, enabling causal identification of neighbourhood effects. Light rail stations are found to drastically improve […]
Read MoreTraffic in Honolulu: How to Make Transitory Pandemic Gains Permanent
By Justin Tyndall and Sumner La Croix During the COVID-19 pandemic, Honolulu traffic became much less congested. Local and state governments could help residents keep the social benefits from traffic control by providing incentives to private firms to stagger hours and/or keep more employees working at home. A congestion zone fee to drive within the downtown-to-Waikiki corridor […]
Read MoreCycling mode choice amongst US commuters: The role of climate and topography
Cycling to work is uncommon in most areas of the US, but relatively common in a particular set of metros and neighbourhoods. Explanations for this spatial heterogeneity often focus on differences in local geography, with some areas being allegedly more suitable for cycling. Tyndall estimates the role of topography and climate in determining the share of a metro’s workers who […]
Read MorePedestrian Deaths and Large Vehicles
Abstract: Traffic fatalities in the US have been rising among pedestrians even as they fall among motorists. Contemporaneously, the US has undergone a significant shift in consumer preferences for motor vehicles, with larger Sport Utility Vehicles comprising an increased market share. Larger vehicles may pose a risk to pedestrians, increasing the severity of collisions. I […]
Read MoreEV driver characteristics: Evidence from Hawaii
Electric vehicles (EVs) offer an opportunity to dramatically decrease greenhouse gas emissions within the transport sector if fueled by renewable energy. Hawaii had been early-on considered an ideal place to launch new EVs because of the limited driving range of its island geography. Though it ranks second in new EV registrations per capita in the […]
Read MoreWho are Driving Electric Vehicles? An analysis of factors that affect EV adoption in Hawaii
This study uses data on EV registrations by zipcode in Hawaii to analyze a variety of demographic and transportation factors that might affect EV adoption. After controlling for population and gasoline prices, zip codes with higher income and educational attainment are associated with higher levels of EV adoption. Longer commute times also influence EV adoption […]
Read MoreEffect of Electric Vehicles on Design, Operation and Cost of a 100% Renewable Power System
This report outlines the effect that electric vehicles could have on the cost of transport and electricity production in the context of a 100% renewable power system (RPS). Results presented here were produced using the SWITCH power system planning model, configured to choose a least-cost plan to achieve 100% renewable power on Oahu by 2045, […]
Read MoreElectric Vehicle Lifecycle Cost Assessment for Hawaii
This study develops a model to estimate the total cost of ownership of electric vehicles (EVs) in comparison to similar internal combustion engine (ICEVs) and hybrid electric vehicles (HEVs). The model includes issues related to purchase/finance, insurance, maintenance, resale value, future fuel prices and access to solar photovoltaic (PV). It also estimates the impact of […]
