The EROAD system does not rely on specialist enforcement architecture or gantries, and could be applied to any road network to implement distance, mass, time, location and emission based vehicle charging. New Zealand operates a Road User Charge (RUC) regime of weight and distance charges for all Heavy Goods Vehicles (HGVs) over 3.5 tonnes and diesel cars. The EROAD technology platform was designed to modernize the New Zealand RUC regime. Engineered to deliver an integrated end-to-end solution, the EROAD eRUC Management System encompasses a secure electronic distance recorder (OBU) and a bank grade web-based payment gateway to purchase and manage RUC and monitor vehicle activity. The eHubo OBU utilises a combination of GPS and GSM providing for maximum flexibility and the ability to support wide-area tolling. Security and integrity has been built into the eHubo design and web application to protect and secure interfaces and information. This paper provides an overview of the EROAD wireless tolling system and the institutional arrangements underpinning the move to eRUC in New Zealand. The innovative model adopted by New Zealand means that the government has not incurred any costs to develop or operate an electronic HGV tolling service. In addition the institutional model encourages the electronic toll provider to be innovative and service orientated because they rely on voluntary take-up within the HGV industry.

In this paper we introduce a coherent methodology showing how to consider the constraints and get the best results out of ITS user services. The methodology defines the steps that should be taken when an intercity corridor needs to be equipped with intelligent transportation systems. In the core of this methodology a linear programming problem is defined to maximize the effectiveness of ITS subservices subject to constraints like budget. For defining the problem, some qualitative parameters turned into quantitative ones using ranking methods. Solving the problem resulted in specific number of each subservice in the corridors under study. Having completed this step, detailed design process and proposing action plan steps follow. INTRODUCTION Nowadays developing countries do not question the benefits of ITS and are more and more aware of the situation in which they have to turn to ITS instead of other traditional approaches of solving transportation and traffic problems. Under this circumstance, two main questions have to be answered before embarking on implementing ITS user services; (1) On what basis can we decide which user services have to be implemented to get the best result, and (2) What

Radio channel in 715-725MHz band is considered to utilize as one of the communication media in these systems. Communication performance has been clarified by vehicle-to-vehicle communication experiments in 2008. However, vehicle-to-infrastructure (V-I) communication in 700MHz band is not considered enough so far. In this paper, the evaluation result of V-I communication performance in order to discuss the applicability of wireless communication in 700MHz band for ITS systems is shown.

Authorities have responded by allowing Basic and Advanced Fatigue management regimes which offer greater flexibility in the working hours for a driver if the transport operator can demonstrate how they will manage the fatigue of the driver. In recognition of the flexible working hours and the growing complexity of managing this task, Authorities have adopted legislation allowing drivers to record their work and rest within an electronic work diary (EWD). Whilst allowed for in law, no EWDs have been approved as Authorities do not have a specification to assess EWDs against. On 7th of November 2008, Ministers agreed to the development of a performance-based specification for heavy vehicle speed and driver fatigue monitoring systems enhancing the use of in-vehicle telematics. This paper reports on the performance-based specification for the heavy vehicle speed and driver fatigue monitoring systems developed by Transport Certification Australia, the functionality of the system and the remaining unresolved issues for governments.

AHS is developed for assisting safety driving in Japan. This system has reached the full-scale operation phase from 2010. To further deployment of AHS, it is important to evaluate quantitatively the effectiveness of their introduction. However because it is difficult to detect human errors, which are the cause of traffic accidents, a method of efficient quantitative effectiveness evaluation of AHS has not been established. Past proving tests or FOTs have been performed through evaluations based on the number of accidents obtained over several years, reduction of vehicle speed, and questionnaire surveys for subjects. This paper introduces quantitative effectiveness evaluation methods of system intruduction, and reports on the results of the verification of the appropriateness of the method based on the results of FOTs on the Metropolitan Expressway.

However, obtaining data with high accuracy using traffic detectors continues to be a challenging problem. Hence, many users and manufacturers have focused on evaluating the performance of traffic detectors. Traditionally, detector evaluation has been performed using the well-known video ground truth method; however, this method requires substantial human workload and time. To overcome the drawbacks, in this research, reference standards for the efficient evaluation of traffic detectors used in intelligent transportation systems (ITSs) have been developed. The reference standards that generate reference data by synchronizing with the detectors under evaluation can be categorized into two types?a stationary reference standard (SRS) for type approval tests and two portable reference standards (PRSs) for onsite verification tests. The SRS comprises our laser sensors placed in each lane and is attached to a gantry. The PRSs consist of two devices?one made from two laser sensors and the other from two magnetic sensors in each lane. In this paper, parameters of the refence standards, such as detection algorithm and data accuracy, are presented in detail. The reference standards developed in this research are expected to ease traffic detector evaluation.

(hereafter “Yazaki”) developed a FEDSS (Fuel Economy Driving Support System). (1) The software incorporates artificial intelligence or AI. This resulted in the upsizing of the software, increase in memory space (required to store data collected for learning), and a significant cost increase. But now Yazaki has succeeded in developing a new method that allows both the software and required memory space to be downsized without reducing the functionality of the system. Also, Yazaki has designed a new gear position direction method, which will be built in a new digital tachograph.

Currently road maintenance departments are mostly considered with the real-time management of the machineries and have up to the minute information about their location and the pattern of transference to other necessary locations. So many technologies and information systems for remote control and real-time monitoring of the equipments have been considered such as wireless and mobile networks and GPS system. Of course to be successful in this multi disciplinary approach, state of the art experiences of other countries and many managerial and technical issues shall be considered very carefully. In this paper we have tried to analyze the various aspects of the system implemented in Iran and address key factors of success in this project.

This training program was developed because previous training was not meeting the identified needs especially in terms of how to acquire and test devices that use ITS Standards. Additionally, this training addresses participants’ needs for online modular training available as needed. Finally, many ITS Standards have been developed or are under development using the Systems Engineering Process (SEP). The new training program will encompass all ITS Standards. It will be easier to train people to acquire and test ITS Standards developed with the Systems Engineering process. Non-SEP ITS Standards will require additional core training.

(VOL) that was specifically developed for identifying the number of occupants in a vehicle. The technology device is called “dtect”. Dtect is an infrared camera system that provides an automated mechanism for determining the number of occupants within moving road vehicles. Dtect can be used for a variety of applications such as congestion charging, road tolling, high occupancy vehicle lane enforcement and occupancy data gathering. The complete dtect system is contained within a single weather and vandal proof housing. Dtect can be installed either roadside on a pole or suspended over the road on a gantry. Once installed and configured dtect can be controlled remotely via an encrypted internet link. In the I-15 test application, the dtect camera is mounted on a fixed pole aimed at a specific lane of travel. Occupancy data is collected in an automated manner continuously for various types of traffic and environmental conditions. The goal of the collected test data is 90% occupany count accuracy. The Final Report documents the execution of various test cases and the results from the data collected.

Turning movement counts are used for coverage counts, warrant studies, and for input for signal timing software. The traditional method to perform Turning Movement Counts is manual use of a Jamar count board. This results in a relatively large variability in the traffic counts at a given intersection from day to day, week to week etc. In addition, the cost of performing manual counts prohibits extensive and frequent counts. This paper describes different methods to automate turning movement counts using modern video detection technology. Whereas one method is evolutionary, using video detection equipment that may have been deployed for stop bar presence detection, a more revolutionary approach makes use of recent developments in video processing to use regular CCTV feeds from an intersection without the need of any additional field hardware.

In this paper, a microscope simulation framework is proposed to develop suitable transportation evacuation plans for Multi-Institutional Centers (MIC). VISSIM is selected as the simulation tool, while the Genetic Algorithm (GA) is used to calibrate driving behavior parameters for VISSIM. As a case study, the Texas Medical Center (TMC) network is modeled and the evacuation plans are developed and evaluated. Results show that the proposed framework is a good and practical tool for developing and evaluating appropriate evacuation plans under similar instances.

The plan laid the framework for the implementation of ITS infrastructure as well as policies and procedures for coordination between stakeholders. The plan’s goal was to facilitate more effective management of one of the region’s most heavily traveled and congested corridors across multiple municipal and disciplinary boundaries. Over the following five years, numerous projects were undertaken to meet these goals including the largest expressway ITS project in the Commonwealth, the implementation of ITS and signal coordination along arterial diversion routes, standardization of ramp signage, implementation of innovative incident management strategies, and the installation of a high speed communications network to better facilitate traffic management and agency-to-agency coordination.

This paper highlights the Wisconsin Department of Transportation’s (WisDOT) role in enhancing evacuation planning documentation for key cities throughout the state and describes lessons learned in preparing these documents. Recognizing the almost infinite number of variables associated with an emergency requiring evacuation, WisDOT emphasized “emergency mobility” approach for the evacuation planning efforts. Therefore, the resulting Evacuation Route and Traffic Control Guidance component of Wisconsin’s emergency evacuation plans serves as an informational resource that focuses on providing incident commanders and responders guidance in planning for and implementing evacuation at almost any location within the jurisdiction.

False calls result in additional manual work at the processing center to eliminate the erroneous calls, whereas missed calls decrease the revenue and more importantly the deterrence effect as violators go unpunished. Traditional means to trigger use inductive loops in the ground which compete with pre-existing stop bar detection loops. Even more critical, they cannot be moved to optimize the detection process after the fact, and the installation creates additional burden for the environment. A more innovative approach is the use of video detection cameras. Using sophisticated tracking algorithms, modern systems can easily adjust to different red light enforcement providers’ needs and algorithms. This paper describes general concepts of the use of video detection for red light enforcement triggering.

Intelligent Transportation System (ITS) applications such as Advanced Traffic Management Systems (ATMS) improve safety, fuel efficiency, and reduce congestion. However, the software life-cycle costs of these systems often place them beyond the reach of small and medium sized agencies. This paper discusses the results of the first implementation of the Intelligent Roadway Information System (IRIS) open ATMS outside of Minnesota. The California Department of Transportation (Caltrans) IRIS demonstration study implemented IRIS within a midsized urban/rural Caltrans district and 2 rural districts that otherwise could not afford an ATMS. Results show dramatic cost savings compared with an existing proprietary ATMS system, increased capabilities, reliability and a number of secondary benefits derived from this multi-agency collaborative approach.

This network would allow City employees to monitor and adjust traffic signal timing, view images from closed circuit televisions (CCTV) and video imaging vehicle detection system (VIVDS) cameras, and provide access to other City employees working remotely in the field such as police officers, building inspectors and public works employees. This project utilizes eight high sites to develop a wireless backbone. The high sites communicate with the traffic signal through point-tomultipoint radios to transmit signal information, CCTV video and provide wireless Hot-Spots. Fiber Optic interfaces are provided to bring the information back to the TMC.

Georgia DOT has proven that better resource management and better customer service can be achieved by leveraging ITS and technology. The program goes beyond the traditional ITS services and reaches outward, past 511 services, to meet other customer needs. By performing triage on all customer requests, more strategic approaches are possible. Business resources and customer service are “joined at the hip”, consequently better management strategies come into focus. “Firefighting” is drastically reduced, and field resources work smarter, not harder. Customers get concise and accurate information, and DOT delivers on promises. The results: 20% reduction in fuel consumption, 20% reduction in work load, and happier customers; A well oiled machine and ITS is the oil.

Technological advancements in Intelligent Transportation Systems (ITS) have led to numerous devices and applications that have the capacity to facilitate enhanced monitoring, management and control of the transportation network. In addition, these advancements have resulted in novel strategies for communicating essential information to the traveling public. While ITS technologies have brought about tangible improvements in network planning, assessment and management, many ITS solutions are limited by their lack of a single salient element ? weather. There has been some discussion of weather within the ITS community, but little has been done to truly realize the full benefits of integrating weather data and information into ITS. This is clearly evident in the roadway surface transportation sector. Statistics published by the United States Federal Highway Administration (FHWA) suggest that on average over 7,000 people lose their lives on the nation’s roadways each year in crashes involving adverse weather. Moreover, some 670,000 are injured in more than 1,560,000 weather-related accidents. In terms of mobility, the FHWA sites weather as the primary factor in roughly 544 million hours of vehicle delay annually. It should be noted that this figure excludes delays associated with the presence of rain and wet roads. It is safe to say that a large part of these delays are the result of weather-induced congestion. This paper attempts to shed light on the efficacy of weather-based ITS solutions. The discussion comprises examples of basic implementations, along with more multifaceted, thought-provoking concepts. The primary goal is to stimulate dialogue and interest in the importance of road weather data and information in ITS technologies, with the hope of inspiring new and improved weather-related ITS solutions and accelerating their adoption.

Several after action reports for recent events in the Gulf Coast region found that response and recovery activities were hampered due to the ineffective flow of information between key stakeholders. While recent revisions to the National Incident Management System emphasize the need for information management and interoperable communications during emergency response, no systems architecture or systems engineering process has been defined to address this critical need. Efforts to achieve interoperability or develop effective common operating pictures will continue to be problematic without the use of an Emergency Management System Architecture and a Systems Engineering process.

The LSBS consists of lighted pavement markers placed in the pavement parallel to the painted intersection stop bar. The pavement markers of the LSBS emit a red light during the red indication of the traffic signal. The LED backplates emit a red light around the perimeter of the traffic signal backplate when the traffic signal indication is red. These two types of devices were installed separately at separate intersections, and a before and after study was conducted to determine changes in crashes, red light running violations, and right turn on red violations. It was determined that right turn on red violations were significantly reduced at the LSBS intersection, while the intersection with the LED backplates exhibited significant reductions in red light running violations. Additional intersections were later outfitted with LSBSs and/or LED backplates, and an aggregate crash analysis for all treatment intersections shows a reduction in red light running crashes over time since the devices were activated.

The transmitted information elicits timely responses to driver behavior in terms of lane changes in a realistic way. A simulation model developed by following the prescribed design was used in a case study application to simulate vehicle advanced lane selection (ALS) by a severe incident in a small network. Simulation results indicate the model results are sensitive both to different market penetration levels of vehicles equipped with wireless communications capabilities, and to control strategy, which therefore gives credence to the utility of the system design.

Route 8, which consists of three tunnels with contra-flow and tidal flow capability, one bridge (the second longest cable-stayed span in the world) and sections of freeways, connects the New Territories of Hong Kong to the Hong Kong International Airport. To manage traffic efficiently on this 13.5m long dual 3-lane high-capacity highway, an advanced TCSS with an implementation cost of CDN$38 million was deployed. The first section of Route 8 was opened in March 2008, and the TCSS has been in full operation since December 2009. Route 8 TCSS contains a total of 1,800 traffic control field devices, such as variable message signs, variable speed limit signs, lane control signs, traffic signals, prismatic signs and flashing beacons. The TCSS also includes functions such as Video Traffic Detection, Automatic Incident Detection (AID), Event Management System, Response Plan Management (RPM), Alarm Management System and Manual Fall Back System. It also interfaces to other systems such as toll system, the adjacent TCSS i.e. Tsing Ma Control Area (TMCA) TCSS managed by another toll organization, Central Monitoring and Control Systems, Supervisory Control and Data Acquisition System (SCADA), and Wind and Bridge Structural Health Monitoring System.

As well as preparations for the events themselves, improving the transportation network is a priority. Included among the initiatives the City of Johannesburg is implementing a bus rapid transport system in primarily an exclusive median, and Intelligent Transport Systems throughout the City. The ITS systems being deployed are part of a developed and coherent ITS road map prepared by SSI/Delcan to meet the requirements and needs for this important event and beyond. In this paper we will provide an overview of Johannesburg ITS integrated deployment from the early conception associated with the development of the ITS road map up to current implementation status including a review of the needs, the approaches considered and the technology and systems implemented. The paper will also present the procurement approaches and procurement options which were analyzed and finally implemented in Johannesburg including the challenges faced along the deployment and how these challenges have been managed.
