Book Description
This project developed an AVL system for INDOT that utilized the statewide wireless network, SAFE-T. This option was chosen after doing a cost analysis of commercial AVL systems that use cellular data communications. The system developed provides real time information collected during snow and ice removal. Information includes weather and road conditions, truck speed, amount of chemicals spread, time, location, plow position, and road temperature. This information is displayed on INDOT GIS maps available through a browser on the INDOT network. The data is also transferred to the MDSS that INDOT uses in winter activities. This system experienced significant data transfer problems and consequently was eliminated as a viable AVL alternative. Therefore other commercial AVL systems were evaluated in this study. Other activities included investigating other hardware options for data collection and data transfer. Also, a hotspot method for data transfer was tested to do batch data transfer. A summer AVL application for paint stripping was developed. Two other commercial systems were evaluated, IWAPI and ThomTech. The IWAPI system was evaluated over three winter seasons and ThomTech for the 08-09 season. Both systems experienced data transfer problems which seems to be the biggest issue with AVL systems. Overall most users were satisfied with how the systems operated and with the information being collected and reported. The project exposed issues that exist with all types of AVL systems. There are plusses and minuses, and costs and benefits. These are described in the report. One outcome is that AVL systems are not a panacea, they offer better information and benefits, but are they economically justifiable? An internal INDOT study was performed during the 08-09 season that shows a savings of $10,000,000 in salt costs that can be attributed to some degree the use of AVL and MDSS.

Book Description
The automotive industry appears close to substantial change engendered by “self-driving” technologies. This technology offers the possibility of significant benefits to social welfare—saving lives; reducing crashes, congestion, fuel consumption, and pollution; increasing mobility for the disabled; and ultimately improving land use. This report is intended as a guide for state and federal policymakers on the many issues that this technology raises.
Applications of Automatic Vehicle Location Systems Towards Improving Service Reliability and Operations Planning in London

Book Description
Technological advances in the transit industry, such as the introduction of Automatic Vehicle Location (AVL) systems, have provided agencies with robust data collection and measurement systems and enabled the development of comprehensive planning and operations tools. This thesis reviews the impact of an AVL installation in London, and demonstrates how data recorded by this system may be used to improve service reliability and operations planning on the London bus network. In particular, this thesis focuses on capabilities which would have been impossible prior to the installation of AVL. Service reliability has traditionally been measured from an operations perspective despite a major objective of the transit agency being to provide high quality service to passengers. A framework for a service reliability analysis is developed which explores new passenger-centric measures used to describe the quality of transit service, which are measured with AVL data. First, an analysis of trends in service reliability and factors that contribute to service reliability is performed in order to gain a better understanding of the environment in which transit services are operated. Three new passenger-centric measures of reliability are then introduced which describe the entire bus passenger experience. These measures are evaluated for a set of origin/destination pairs on six bus routes, and the differences in the perception of reliability between the new measures and the traditional measures are identified. The analysis demonstrates that while the traditional measures of reliability are relevant, the new measures provide additional insight. Recommendations are made with regard to implementing these new measures, providing better passenger journey information by applying these measures, and improving service control practices by monitoring these measures. AVL data provides for the development of more robust operations plans since these data allow for a greater degree of accuracy when measuring point to point running times. A framework is presented for how running times measured with AVL may be used to assess the efficacy of current operations plans and aid operations planners in vehicle scheduling. Recommendations are made with regards to how AVL data should be used to evaluate the effectiveness of existing schedules and develop more robust schedules.

The Knowledge Solution. Stop Searching, Stand Out and Pay Off. The #1 ALL ENCOMPASSING Guide to AVL. An Important Message for ANYONE who wants to learn about AVL Quickly and Easily... ""Here's Your Chance To Skip The Struggle and Master AVL, With the Least Amount of Effort, In 2 Days Or Less..."" Automatic vehicle location (AVL or locating; telelocating in EU) is a means for automatically determining the geographic location of a vehicle and transmitting the information to a requester. Most commonly, the location is determined using GPS, and the transmission mechanism is SMS, GPRS, a satellite or terrestrial radio from the vehicle to a radio receiver. GSM and EVDO are the most common services applied, because of the low data rate needed for AVL, and the low cost and near-ubiquitous nature of these public networks. The low bandwidth requirements also allow for satellite technology to receive telemetry data at a moderately higher cost, but across a global coverage area and into very remote locations not covered well by terrestrial radio or public carriers. Other options for determining actual location, for example in environments where GPS illumination is poor, are dead reckoning, i.e. inertial navigation, or active RFID systems or cooperative RTLS systems. With advantage, combinations of these systems may be applied. In addition, terrestrial radio positioning systems utilizing an LF (Low Frequency) switched packet radio network were also used as an alternative to GPS based systems.

Book Description
The 17 chapters in this book, which evolved from a conference on measuring the contributions of ITS sponsored by the California Department of Transportation in February 2002, examine the costs and benefits of ITS in an economic and business policy context. Section 1 examines the broad theme of how and what ITS contributes to the economy and how one makes a business case for ITS. Section 2 includes three chapters on ITS applications in mass transit. Section 3 explores ITS applications in the automobile/highway system. Section 4 considers integrative issues including how ITS is perceived and how it can be positioned to improve surface transportation. This volume will be especially useful to researchers and policy makers working in transportation, transportation engineering, and the economic analysis of transportation systems.
