It provides a way for Caltrans (California Department of Transportation )Traffic Management Centers (TMCs) to determine whether or not SOHVs should be permitted in HOV facilities and to convey that information to drivers. It also provides insight in understanding various HOV restriction scenarios and their impact on HOV lane and mainline congestion. Researchers studied, via simulations, the effects of permitting or restricting eligible SOHV from use of HOV facilities. Results from the simulations showed that reduction in vehicles eligible to use HOV lane (not just SOHV but any vehicle) could reduce not only the delay experienced by HOV vehicles but also the total system delay.]]></description><pubDate>Mon, 04 Mar 2013 19:37:00 GMT</pubDate><guid>http://trid.trb.org/view/1245312</guid></item><item><title>Monitoring and Improving Roadway Surface Conditions For Safe Driving Environment and Sustainable Infrastructure</title><link>http://trid.trb.org/view/1245304</link><description><![CDATA[Toward the goal of reducing collisions while maintaining the integrity and sustainability of roadways, projects in France and California have been developed to: Evaluate the effectiveness of roadway surface improvements in reducing collisions; understand and model the deterioration of skid resistance over time; explore alternative data collection methods of monitoring skid resistance within the framework of cooperative infrastructure and vehicles; and develop a real-time system of monitoring roadway surface conditions and offering alerts to drivers. Delays and budget issues have impeded collaboration and limited input from French researchers. An extensive literature review is presented.]]></description><pubDate>Mon, 04 Mar 2013 18:23:00 GMT</pubDate><guid>http://trid.trb.org/view/1245304</guid></item><item><title>Biofuel Boundaries: Estimating the Medium-Term Supply Potential of Domestic Biofuels</title><link>http://trid.trb.org/view/1218684</link><description><![CDATA[The physical supply potential of biofuels from domestic municipal solid waste, forestry residues, crops residues and energy crops grown on existing cropland using optimistic assumptions about near-term conversion technologies is estimated. It is technically feasible to produce a significant amount of liquid biofuel (equivalent to 30-100% of 2003 gasoline demand) without reducing domestically produced food and fiber crops or reducing the total calories available as domestic animal feed. Most of this supply can be attributed to the potential of energy crops, with the combination of municipal solid waste and forestry residues supplying between 10% and 30% of recent gasoline demand. The modeling approach to energy crops is unique in that it explicitly models interactions between the feed and fuel system using an optimization procedure that adjusts cropland allocation among major crops subject to a simple food security constraint. Sizable increases in biofuel production need not result in decreased availability of food or animal feed, but will require changes in the composition of livestock diets. While domestic biofuels can play a large role in transportation, achieving such high levels of ethanol production may not be socially or ecologically desirable, or may be extremely costly. Policies designed to protect natural resources and stabilize food prices should be implemented early in order to achieve a reasonable level of biofuel production that avoids pushing these boundaries.]]></description><pubDate>Mon, 05 Nov 2012 16:58:00 GMT</pubDate><guid>http://trid.trb.org/view/1218684</guid></item><item><title>Bike-and-Ride: Build It and They Will Come</title><link>http://trid.trb.org/view/1225438</link><description><![CDATA[Converting park‐and‐ride to bike‐and‐ride trips could yield important environmental, energy conservation, and public‐health benefits. While cycling in general is becoming increasingly popular in the United States, it still makes up a miniscule portion of access trips to most rail transit stations. At several rail stations of the Bay Area Rapid Transit (BART) system, 10 percent or more of access trips are by bicycle, up considerably from a decade earlier. This paper adopts a case‐study approach to probe factors that have had a hand in not only cycling grabbing a larger market share of access trips to rail stops but also in the enlargement of bike access‐sheds over time. Both on‐site factors, like increases the number of secure and protected bicycle parking racks, as well as off‐site factors, like increases in the lineal miles of bike‐paths and bike boulevards, appear to explain growing use of bicycles for accessing rail stations. The adage “build it and they will come” holds for bicycle improvements every bit as much as other forms of urban transportation infrastructure. Pro‐active partnerships between transit agencies, local municipalities, and bicycle advocacy organizations are critical to ensuring such improvements are made.]]></description><pubDate>Wed, 12 Dec 2012 16:24:00 GMT</pubDate><guid>http://trid.trb.org/view/1225438</guid></item><item><title>Mobile Millennium: GPS Mobile Phones as Traffic Probes, California Networked Traveler - Safe Trip 21 Phase II</title><link>http://trid.trb.org/view/1148408</link><description><![CDATA[Recent advances in mobile devices and internet technology have led the California Department of Transportation (Caltrans) to investigate a data collection solution that offers improved data reliability and availability at a significantly lower cost. It has been postulated that information from GPS cell phones could provide position and speed data -- referred to as probe data -- for highways and arterials in near real time over much of the transportation network. The Mobile Millennium project was established to determine if the collection and use of probe data for traveler information and traffic management was technically and institutionally feasible in order to provide a more reliable solution to the collection of traffic data. The Mobile Millennium project deployed thousands of phones in the San Francisco Bay Area in a short timeframe. The traffic data collected from those phones was processed into meaningful traveler information and fed back to a variety of channels, including the mobile handsets that generated it in the first place. Mobile Millennium established a community of individuals that generated valuable mobile content for one another and for society at large. The privacy of those individuals was strongly protected. It was also one of the first instances of crowd sourcing of GPS data for travel information purposes.]]></description><pubDate>Tue, 21 Aug 2012 17:35:00 GMT</pubDate><guid>http://trid.trb.org/view/1148408</guid></item><item><title>SmartBRT: a set of planning, analysis and evaluation tools for bus rapid transit: final report year 1 of 2</title><link>http://trid.trb.org/view/1210924</link><description></description><pubDate>Sat, 25 Aug 2012 01:05:00 GMT</pubDate><guid>http://trid.trb.org/view/1210924</guid></item><item><title>Evaluation of the ACC vehicles in mixed traffic: lane change effects and sensitivity analysis</title><link>http://trid.trb.org/view/1210923</link><description></description><pubDate>Sat, 25 Aug 2012 01:05:00 GMT</pubDate><guid>http://trid.trb.org/view/1210923</guid></item><item><title>Evaluation of the effects of intelligent cruise control vehicles in mixed traffic</title><link>http://trid.trb.org/view/1210922</link><description></description><pubDate>Sat, 25 Aug 2012 01:05:00 GMT</pubDate><guid>http://trid.trb.org/view/1210922</guid></item><item><title>Integration of fault detection and identification into a fault tolerant automated highway system: final report</title><link>http://trid.trb.org/view/1210881</link><description></description><pubDate>Sat, 25 Aug 2012 01:03:00 GMT</pubDate><guid>http://trid.trb.org/view/1210881</guid></item><item><title>Technology analysis in interregional goods movement</title><link>http://trid.trb.org/view/1188200</link><description></description><pubDate>Fri, 24 Aug 2012 07:54:00 GMT</pubDate><guid>http://trid.trb.org/view/1188200</guid></item><item><title>Frecon2 user's guide</title><link>http://trid.trb.org/view/1188193</link><description></description><pubDate>Fri, 24 Aug 2012 07:54:00 GMT</pubDate><guid>http://trid.trb.org/view/1188193</guid></item><item><title>Improved dynamics and performance for the Frecon freeway simulation model</title><link>http://trid.trb.org/view/1188192</link><description></description><pubDate>Fri, 24 Aug 2012 07:54:00 GMT</pubDate><guid>http://trid.trb.org/view/1188192</guid></item><item><title>A decision making framework for the evaluation of climbing lanes on two lane two way rural roads: final model selection, simulation methodology and proposed data collection</title><link>http://trid.trb.org/view/1188181</link><description></description><pubDate>Fri, 24 Aug 2012 07:54:00 GMT</pubDate><guid>http://trid.trb.org/view/1188181</guid></item><item><title>A decision making framework for the evaluation of climbing lanes on two lane two way rural roads: preliminary evaluation of candidate models for use in the project</title><link>http://trid.trb.org/view/1188180</link><description></description><pubDate>Fri, 24 Aug 2012 07:53:00 GMT</pubDate><guid>http://trid.trb.org/view/1188180</guid></item><item><title>Optimal strategies for distributing non storable items without transhipments</title><link>http://trid.trb.org/view/1188149</link><description></description><pubDate>Fri, 24 Aug 2012 07:52:00 GMT</pubDate><guid>http://trid.trb.org/view/1188149</guid></item></channel></rss>
