Transportation agencies historically have sought to cut congestion by adding capacity. Alternatively, modest pricing signals could be more cost effective and efficient at managing demand, saving public agencies much more in the long run. One example is the I-65 bridge spanning the Ohio River between Kentucky and Indiana. The bridge carried close to 140,000 vehicles per day prior to construction. The two states spent about $1 billion to increase the capacity of the crossing from six lanes to twelve, enough to handle up to 250,000 vehicles per day. To recoup some costs, a toll of less than $3 per trip was instituted, discounted for regular commuters. Once tolling began in 2017, daily trips dropped to about 60,000.
Two recent studies demonstrate two approaches to reducing driving. A Swedish study looked at what types of messages influence the choice to drive, while a report from Virginia shows that tolls on the I-66 corridor outside Washington have made a difference in both mode choice and when drivers travel.
New research out of California looks at the effect of priced parking on commuter mode choice and transportation costs for low-income households. Findings from two studies suggest raising the price of commuter parking by 10 percent could lower car use by as much as three percentage points and, while residential parking permits could hit low-income households hardest, few households would be disproportionately affected. Moreover, revenues from paid parking could offset any potential burden.
Transcending Oil, released in April 2018, describes Hawaii’s path toward meeting its ambitious clean energy goals by 2045. The report was commissioned by Elemental Excelerator and prepared independently by Rhodium Group and Smart Growth America. It focuses mainly on transitioning the electrical grid to renewable energy while moving large numbers of vehicles to electric power but also points to the importance of managing overall travel demand through transportation policies and investments. This technical guide describes the methods and findings behind Transcending Oil’s travel demand forecasts, developed by SSTI and Smart Growth America.
StreetLight Data, which provides trip-making data from mobile devices and smartphone apps, has just launched a new interactive Congestion Analysis tool. The tool lets subscribers identify congested roads by time of day, break down the traffic in terms of trip length, trip purpose, and other characteristics, and then focus on specific strategies to relieve demand.
MassDOT is among a growing number of state agencies tackling sustainability efforts in the transportaiton section and its approach offers valuable lessons for others. number of state agencies tackling this issue and its approach offers valuable lessons for others. This paper traces the evolution of MassDOT’s sustainability efforts, beginning with its revised Project Development and Design Guide, published in 2006, and ultimately encapsulated in its ongoing GreenDOT program, launched in 2010. These efforts represent the combined actions of state legislators, agency leaders, and personnel at all levels of MassDOT.
According to the results of a just-released survey, the United States is undergoing a parking revolution as the industry embraces a variety of new technologies that make it easier for people to find and pay for parking, and for parking authorities to better manage it.
State officials across the country are facing the same challenges. Revenues are falling and budgets are shrinking while transportation demands grow. Most state Departments of Transportation (DOTs) have ambitious goals: improve safety, reduce congestion, enhance economic opportunity, improve reliability, preserve system assets, accelerate project delivery, and help to create healthier, more livable neighborhoods, just to name a few.
The handbook provides 31 recommendations transportation officials can use as they position their agencies for success in the new economy. The handbook documents many of the innovative approaches state leaders are using to make systems more efficient, government more effective and constituents better satisfied.
Heavy vehicle traffic in places with pedestrians and bicyclists increases the chance of a crash, and this increased risk can affect parent decisions on school travel. This brief looks at the problem of traffic congestion, provides an overview of local programs that successfully measured traffic reductions and outlines steps that programs can take to measure impacts of their activities.
This report was produced by SSTI at the request of the Kansas Department of Transportation in order to better understand the implications of school site selection, particularly transportation-related costs, and how to improve the site selection process in Kansas. It provides a series of recommendations for improving the school site selection process in Kansas with a focus on increasing understanding and coordination between school districts and other levels of government that may be impacted by their decisions.
