During testing, collected log data needs to be checked frequently to monitor progress and that the systems are running correctly. After these first validation checks and having properly collected data, log data is
enriched and post-processed. Finally, log data and post-processed outputs are provided to analysts, along with extensive metadata documentation explaining details of the test and data. Data management should also oversee formulation of user agreements and conditions for sharing data.

A multimodal strategy and action plan have been developed in the year 2010 to support a broader implementation of ITS in Sweden. The plan includes approximately 40 measures which demand cooperation between many different players – private as well as public – for their implementation. This plan has a five-year time perspective, i.e. up to year 2015.
The ITS Board has identified areas of development where efforts have to continue in order to achieve greater impact of ITS within the Swedish transport system.

This paper presents a part of this effort that may contribute to ongoing discussions concerning guidelines for assessing visual-manipulative demands of in-vehicle technologies. This paper reports the eye tracking and driving performance data from 24 younger adults (20-29 years). While participants performed a driving task in a simulator, they also completed several secondary tasks: 1) phone dialing with either a flip-phone or a smartphone with touchscreen, 2) address entry with a portable GPS, and 3) radio tasks at three difficulty levels. Collected eye behavior measurements were compared against the Phase 1 guidelines from the National Highway Traffic Safety Administration. Study results were consistent with previous research on secondary tasks and provided data that are relevant to further development of metrics based on Eye Glance Testing Using a Driving Simulator.

While DMSs are intended to improve efficiency and safety of road networks, little has been done to study the effect of the signs on driver safety and their localized safety impacts. This research employs ground truth data as the basis to investigate the issue in State of Maryland in a four-year period (2007-2010). The results show no significant difference between the accident pattern in the proximity of DMSs and the onward adjacent segments. On-and-off study is also conducted on DMS operation status (on/off). The results converge with the previous analysis suggesting that there is no meaningful relationship between occurrence of accidents and presence of DMSs. Besides, statistical analysis on DMS characteristics and accidents in impact areas are performed.

The VSL system manages freeways by changing the speed limits according to the traffic status, weather conditions and environmental indexes. It has been employed on freeways in the US and European countries. This paper provides a review of the U.S. and European practices of VSL systems. These VSL systems have been summarized from the aspects of system objectives, VSL control algorithms, VSL evaluation methods, results and driver compliance issues. Summary tables are presented to summarize these issues and provide additional information about the systems' regulation, types of data collection and display devices. Finally, based on the implemented systems, suggestions for future implementations of VSL system have been made.

The STA is working both nationally and with other European countries to increase the knowledge of ITS effects and benefits. The EasyWay project plays an important role in collecting and presenting ITS benefits throughout Europe. Nevertheless, the valuable knowledge from EasyWay is not known by transport officials at a local level. On a national level there is an increased interest to promote ITS in a broader perspective and to increase ITS deployment for multimodal transport services both for passengers and goods.

However, field studies are limited in the scope of data collected and reportable measures of effectiveness. Studies performed in microsimulation provide much more thorough inputs and outputs but are time-consuming and expensive, making it impossible to simulate each unique situation prior to deployment. This study addresses these issues by providing the first scientifically-rigorous simulation of the InSync adaptive system using a carefully built field-like microsimulation model. The study will help practitioners and other stakeholders understand adaptive traffic control’s performance not only in normal traffic conditions but also in unique situations to which the system must adapt to optimize signal timings.

It focuses on what WRTM strategies exist, where they have been used, the benefits realized, what improvements are needed, and how to implement and evaluate them as part of transportation operations. As of today, WRTM exists mostly as individual systems designed to address spot-specific issues. While such systems will continue to be essential to the safety and mobility of motorists, the next evolution of WRTM needs to be more regional in nature where operational agencies can implement progressive actions in advance of, during, and after weather events.

The pilot project aims to test and validate the smart charging system and the digital communication system between vehicles and electric power grids, with 5 Prius Plug-in Hybrid vehicles. The system can control the optimum charging setting automatically, which is able to accommodate the
requests both from utility companies and customers, by taking into account demand response programs and tariff tables offered by utility companies, and also the logging data from each customer with respect to charging timing. In this paper we explain the smart charging system
and communication architecture, and show the initial analysis of the system performance and monitors’ behavior.

VSP and OMB are highly related to speed and acceleration, which are however difficult to directly obtain through field observations, especially when the roadway networks are still in planning and/or a new ITS technology is to be tested during simulation stage. The driving simulator is a good tool to emulate the vehicle movement, and thus could be used to synthesize VSP and OMB for emission estimation purposed. This paper develops a fuzzy based scenario to calibrate the simulated OMB and real OMB. Calibration result show that the OMB distribution errors are reduced for more than 50%, and the vehicle emissions based on real and simulated traffic data are very similar (with a error of less than 2%.)

Safety messages can often be classified by the sender as routine or critical, and placed in different Access Categories (ACs) to give the critical messages priority channel access. In this paper we address the problem of how to assign routine safety messages to priority classes. In particular, we describe an algorithm that computes a metric called Suspected Tracking Error (STE) and assigns the priority class of a message based on the current value of STE. We use an enhancement of an STE approach previously published by others. Packets with the largest STE are assigned to the highest priority class. Packets with moderate STE are assigned to the lower priority class. Simulation results demonstrating the benefit of the proposed algorithm are provided.

For stop sign areas, usually our countermeasure is to remove all the obstructions. For signalized intersections, we usually improve the safety by setting up the signal lights in an optimized layout. However, many accidents still happen despite of these traditional methods. Radio Frequency Identification (RFID) can provide effective solutions to improve the operations in work zones, stop sign areas and signalized intersections. The purpose of this research is to identify how to improve the traffic safety and achieve better air quality in these areas by using RFID. With the implementation of such advanced warning system, it is envision that crash rates at woke zones and intersections will be greatly reduced and the surrounding environment will be improved.

A Retrofit Safety Device (RSD) and a Data Acquisition System (DAS) has been developed for use in commercial vehicles during the Safety Pilot. The RSD kit includes at a minimum a DSRC radio, a connection to the vehicle data bus, and a driver interface that utilize Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication to facilitate multiple safety applications including Emergency Electronic Brake Lights, Forward Collision Warning, and Curve Speed Warning. This paper will highlight the technical approach involved in creating the RSD kits as well as documenting the lessons learned and the next steps in enhancing vehicle safety via the use of retrofit devices.

Many agencies have checked off social media integration from their lists after establishing one-way feeds that simply serve as yet another channel for broadcasting information already published elsewhere. This approach ignores the more interesting and complex interactions that are possible in two-way feeds.

This paper discusses one agency's initial exploration into two-way social media. Working with the Idaho Transportation Department (ITD) in the U.S., Castle Rock Associates, Inc., developed a software module called CARS-Vox to facilitate direct public input into ITD's winter condition reporting system. These crowd-sourced updates are not intended to change, replace or delete any official agency reports, but can help supplement or update information that the state has provided, while also calling the state's attention to potentially serious road conditions in the state that require response.

With this continued rapid growth, there is a growing need for a better, more cost-effective method to more efficiently manage the traffic demand. To address this need, a public private partnership was formed between the City of Surrey, Delcan Corporation and Transport Canada to implement and evaluate an Adaptive Traffic Signal Control (ATSC) Pilot Project. The scope of the project was to demonstrate the integration of an open platform traffic adaptive control system with the City's existing traffic signal control infrastructure, and to evaluate the benefits of adaptive control. This paper describes the results of the system
deployment and actual field surveys, including lessons learned.

This program was realized in 2009 by funding from the I-95 Corridor Coalition, led by the New York State Department of Transportation, and called the Commercial Vehicle Infrastructure Integration (CVII) program. The CVII program focuses on developing, testing and deploying Connected Vehicle technology for heavy vehicles. Since its inception, the CVII program has developed numerous Vehicle-to-Vehicle and Vehicle-to-Infrastructure applications for trucks that leverage communication with roadside infrastructure and other light and heavy duty vehicles to meet the objectives of the program. This paper will highlight the efforts performed and lessons learned under the CVII program and the insights provided into the broader impact and remaining hurdles of enabling Connected Commercial Vehicles nationwide.

This program involved equipping nearly 3,000 cars, trucks, and busses with Dedicated Short Range Communication (DSRC) based on-board equipment to allow the vehicles to communicate with other vehicles and the infrastructure to enable a number of communication-based safety applications. To ensure quality data from the experiment, a structured process was needed to test and evaluate the in-vehicle safety devices for potential use in the experiment. This paper will describe the processes, procedures, and tools that were developed to perform this testing along with presenting lessons learned from the effort and the foundation that was established to enable future testing of Connected Vehicle in-vehicle safety devices.

Therefore, establishing a methodology and a test platform is essential to be able to assess conformance with standards, criteria and business rules in complex environments during deployment, as well as the interoperability requirements for agencies regulation and enforcement. However, if all tests from the verification protocol are manually executed, this will require a huge effort and the like wood possibility of human errors. Hence, automating the process becomes essential to enable a sizable reduction of cost and time and the improvement on precision, reliability and repeatability of the process. This paper describes the methodology and results through automated testing of an ITS equipment using standardized platform TTCN-3 for approval of conformity of Electronic Toll Collection in Brazilian scenarios.

Typically, a common practice to provide traveler information to motorists would include installing portable data collection devices and displaying real-time traffic information on changeable message signs (CMS). However, these systems are costly and require efforts that can be quite extensive in regards to; initial engineering, system installation, and adjustments along with the collection of validation data to measure accuracy. MnDOT continually seeks to take a proactive innovative approach to enhance safety, mobility and efficiency on Minnesota's roadways. In regards to work zone travel time, the overall objective is to obtain and display accurate, reliable third party real-time traffic data information as a cost effective alternative to inform motorists of travel times and/or travel delays.

The robustness of the solution has been improved through the use of dead reckoning and map matching techniques. With the recent advances in ADAS, and car to car communications for safety systems the demand for positioning accuracy is increasing from knowing which road, to knowing not only which lane a car is in, but also where in the lane the car is positioned. This paper describes some of the challenges and potential solutions for "where in lane" positioning for the automotive industry.

This paper explores the current state-of-the-practice in electronic signage, which is being influenced by three factors: 1) the increased use of mobile media that could be used to provide transit information; 2) agencies increasingly providing open data allowing the development of third-party transit information applications, and 3) the infrastructure requirements, and operations and maintenance concerns regarding the electronic signs. The paper covers five elements of electronic signage: the underlying technology, sign technology, characteristics of the information, resources required to successfully deploy and manage electronic signage, and decision process that is used to determine if signage will be deployed; where the signage will be located; and what will be displayed on the signage.

The major driver for this technology was the development of liquid de-icing chemicals. Early FAST systems were relatively simple, but operational enough to prevent accidents. The use of data from Environmental Sensing Stations was integrated in to the control algorithms and proved to be a huge advancement. However the embedded pavement sensors did not prove reliable enough to allow widespread confidence in the systems. The latest development that has finally delivered the fully automated and reliable FAST trigger is the use of non-intrusive road sensors. FAST system, even in their limited use as an ITS tool, has proven to be an extremely effective way to reduce crash rates in where used. This paper will highlight the benefits FAST systems, when used with the latest activation technology, can be an important ITS tool.

This has largely been the case for Road Weather Information Systems (RWIS) which can have a huge impact on timely and efficient winter road maintenance. All road users are becoming more demanding and it is a priority for road authorities to not only provide a high level of winter maintenance, but also to justify their cost. For example the Idaho Transportation Department (ITD) budget is approximately $7.5 million annually for winter maintenance materials. However until recently it was difficult to assess how well the money was being spent and what efficiencies in terms of mobility and safety were being realized on their road network.
This paper describes how a key performance measure (KPI) for winter maintenance was developed and implemented. It also outlines some of the immediate and potential benefits of the KPI.

Nevertheless, for operators and for the relevant legal entities, Free Flow tolling presents a major challenge, requiring the development of specific legislation, and modes of operation completely different from traditional toll collection. With Electronic Toll Collection, we talk about "Customers" instead of "users". This is a new vision, because customers need to be cared of and marketed. The objective of this paper is to give guidelines to manage these new customers and also to emphasize on the new challenge to face of : management of non-subscribers, development of channel of communication, and enforcement management.

Currently private rescue programs such as OnStar are providing rescue services for fatality reduction. Also, the US government started NG-911 initiative. With this initiative the 911 system, which accepts only voice calls, will be upgraded to accept various types of calls, mails and messages, so ACN (Autonomous Collision Notification) messages initiated by airbags or vehicle sensors can be automatically transmitted to a PSAP (Public Safety Answering Point), i.e. police, ambulance or fire stations. Also in Europe, emergency call mandatory is being discussed. In this paper, we first address traffic crash statistics and emergency call statistics. Then we introduce both telecommunication and invehicle technologies associated with NG-911 deployment. Finally, we address challenges for NG-911 deployments, i.e. regional non-uniform NG-911 during transition term and PSAP operation center's call reception capability.
