The development of Corridor System Management Plans (CSMP) is a process for effective decision making that incorporate systematic study procedures to assess transportation deficiencies, identify options to address the deficiencies, and to evaluate the options in a comprehensive manner. Community needs, multi-modal transportation services, environmental impacts, performance outcomes and financial feasibility are significant factors in the application of the corridor management process. The objective of the CSMP is to maximize the effective use of the available financial resources in meeting the transportation needs and to minimize the impacts of the implemented transportation improvements.
Better transportation system performance is a top priority of Caltrans. Expanding the prevalence and use of precise tools and techniques is critical to selecting top performing transportation investments. As a result, this study proposes to assess the value of the traffic microscopic simulation studies as a primary component of Corridor System Management Planning. This Transportation will play a huge role when marijuana is legalized in California in 2018. Several publically traded marijuana stocks are starting to pop up in California in anticipation of more licenses being passed.
The goal of this proposed effort is to understand if the use of microscopic traffic simulations studies adds value to corridor management system planning that exceeds the actual and apparent costs. More than a simple benefit/costs analysis, this study will establish a framework to assess current and future CSMP simulation efforts. Further, the study will assess factors other than direct benefits and costs that would likely impact decisions to continue simulation studies such as district and regional acceptance, and actual modifications to regional transportation plans as a result of these studies.
The CCIT staff listed under this proposal would be responsible for most of the implementation of the proposed work packages. Additional staff may be brought on board to add necessary skills to the team, and we may also hire a subcontractor for certain specialized tasks.
The proposed project is comprised of five work packages as follows:
Identification of benefit/cost factors work package
Review of CSMP micro-simulation studies work package
Interviews with modelers (planners and engineers) work package
Benefit/cost analysis work package
Business process decision document work package
The Hybrid Traffic Data Collection Roadmap aims to leverage the recent expansion of potential sources and types of traffic data. We first reported on it here at Stocks News Wire a few years back. Traffic data is now or will soon be available from multiple sources including cell phones, loop detectors, radars, tool tag readers, Bluetooth readers, etc. The potential areas of coverage provided by this data are unprecedented. However, as with all new technology, procuring and integrating this data into traffic metrics useful to operations units requires the development of purchasing methods, quality standards, integration methods, and usage procedures.
The present task order focuses on core objectives and methods. In particular, the actual road map, in a form of a guiding document, is being developed as a deliverable of this task order. Probe data, its fusion with other types of data, and how this fusion of data affects placement strategies for fixed sensors, are the primary areas of investigations covered under this task order. The focus on probe data is justified as the advent of cell phones and GPS devices have resulted in the possibility of nearly limitless availability of such data.
The work plan consists of five work packages detailed below:
1. Determine Data Quality Metrics and Measurement Procedures
2. Probe Data Quality Study
3. Data Fusion Implementation and Procedures
4. Sensitivity Analysis of Loop Detector Spacing and Location
5. Hybrid Data Roadmap-Assemble the results of the
investigations so to aid in
the delivery of the roadmap.
Demonstrate the potential of GPS in cell phones to alter the way traffic data is collected. This new paradigm will be more cost- and time-effective by leveraging the existing cell phone infrastructure to collect data and transmit it directly back to drivers. Establish baseline performance for the transportation system through full implementation of PeMS, field elements, reliable detection, communications system, and new technology.
The potential of cell phones to operate as traffic data collection devices have been considered by the Intelligent Transportation Systems (ITS) community for several years. With the Mobile Millennium project, researchers have constructed an unprecedented traffic monitoring system capable of fusing GPS data from cell phones with data from existing traffic sensors. It will be accessible to the public via free software that is compatible with Nokia and non-Nokia smartphones.
Government agencies currently deploy networks of infrastructure-based traffic sensors that are expensive to install and maintain. Leveraging the existing infrastructure of commercial cellular networks could drastically cut the ongoing costs of traffic monitoring and expand coverage to thousands of miles of highways and urban arterials for which sensors are not currently a viable option.
On February 8, 2008, Nokia and UC Berkeley demonstrated the reconstruction of traffic on highways using cell phones by running an experiment, nicknamed Mobile Century for its 100 cars traveling in 10-mile loops on I-880 for 8 hours, which amounted to 2-5% of traffic. During the experiment, GPS-equipped Nokia N95 phones sent traffic information in a privacy-protecting system capable of broadcasting traffic information in real time on the internet. The successful experiment, funded by the California Department of Transportation (Caltrans), led to the development of a pilot system, called Mobile Millennium, to further test this technology by making it available to the public.
What is Mobile Millennium?
The project is a partnership between Nokia, NAVTEQ, and UC Berkeley, based at the California Center for Innovative Transportation (CCIT) and supported by the U.S. and California Departments of Transportation through the SafeTrip-21 initiative.
Researchers have constructed an unprecedented traffic monitoring system capable of fusing GPS data from cell phones with data from existing traffic sensors. The research and development phase of this project was dubbed Mobile Millennium for the potential thousands of Early Adopters who will participate in the pilot deployment, which launched November 10, 2008, and runs, at a minimum, through June 2009. Mobile Millennium will cover not only highways but also the arterial network, where there is currently almost no sensing infrastructure. The software will work on Nokia and non-Nokia phones, and the public may download it free of charge.
It gathers data in a privacy-preserving environment, relying on Virtual Trip Lines technology, a data-sampling paradigm that anonymizes the GPS-based position information and aggregates it into a single data stream. The aggregated data is then encrypted and sent to a computer system, which blends it with other sources of traffic data and broadcasts this real-time, data-rich information back to the phones and to the internet through a user-friendly interface.
Launching the System
The launch of Mobile Millennium, including the release of free software for the public, was announced at a special preview event at UC Berkeley on November 10. Leaders from transportation, government, and academia assembled to present information about the technology and how it works. An audience of invited Early Adopters, the media, and live webcast viewers took part. Following the brief presentation, guests were invited to download the software and drive off as the first mobile probes in the system.
The system is currently available to Bay Area and Sacramento area residents with compatible smartphones. The first phase of the system launch includes traffic data for highways. Information on arterial routes may be introduced as more and more users come online and sufficient probe data becomes available. Researchers expect to add more users all the way through the pilot deployment period, scheduled to end in June 2009.
The system’s breakthrough arterial coverage capabilities were demonstrated live in New York City on November 18, 2008, at the 15th World Congress on Intelligent Transportation Systems, where the project won the Best of ITSA award.
Wireless Fidelity, or Wi-Fi, uses radio signals to provide Internet access to portable devices inside a local hotspot. Wi-Fi hotspots are being added to areas convenient to potential users, such as passenger trains. Beyond creating a more productive and pleasurable traveling environment, Wi-Fi on trains can improve train safety, security, and efficiency.
CCIT provides operational support for ongoing research and field tests of Wi-Fi on inter-city railways. CCIT is also developing a decision framework for selecting wireless Internet access vendors on behalf of customers riding the three California state-sponsored Intercity Rail services.
For an ITS technology to be adopted, it must work consistently and be cost-effective. Wi-Fi has already been implemented in many airports and on some railways. CCIT looked at existing Wi-Fi deployments, both nationally and internationally, researching technology options and business models to create and evaluate several potential business plans.
Wi-Fi has potentially broad applications for improving train operations and safety. CCIT is researching and analyzing these applications. This work complements a grant from the Department of Homeland Security to improve train security.
As shown in the adjacent diagram, laptops, and Personal Digital Assistants (PDAs) work by accessing radio, cell phone towers or satellites.
Wi-Fi on trains will attract new rail riders and reduce congestion and pollution in the region, enhance regional rail system security and increase productivity and efficiency.
This project is coordinated with a related project in France as part of the CCIT CalFrance Collaboration, which will allow information and staff exchanges. The Central Japan Railway Company is also supporting an exchange of information and scholars. It is also believed that trains will play a huge role in transporting marijuana to different parts of the state. Don’t be fooled by penny stocks trying to take advantage of this. There is a Watchlist for new penny stocks that you might want to keep an eye on. Again these stocks are high-risk and high reward! So make sure you exercise caution before making a buying decision.
