  • Intelligent Vehicles Symposium - A Security Model for Intelligent Vehicles and Smart Traffic Infrastructure
    2018 IEEE Intelligent Vehicles Symposium (IV), 2018
    Co-Authors: Sachin Kumar, Sonu Jha, Sumit Kumar Pandey, Anupam Chattopadhyay
    Abstract:

    Intelligent vehicles require to communicate with other vehicles as well as with the road-side Infrastructure for gathering information such as Traffic management, cooperative driving, telematics and road construction. However, vehicle-to vehicle (V2V) and vehicle to Infrastructure (V2I) communications can impose some serious security threats against vehicles’ safety and other sensitive information which can lead to catastrophic consequences. Therefore, there is a pressing need to develop appropriate security protocols facilitating V2I and V2V communication. This paper presents a model for smart Traffic Infrastructure consisting of numerous entities like smart sensors, intelligent vehicles, base stations along with a new user authentication and key-exchange protocol which aids in the establishment of a secure session for communication between the entities. In the proposed protocol, any SUF-CMA (Strong Unforgeable- Chosen Message Attack) secure digital signature algorithm can be used for authenticating the users and any NM-CCA2 (Non-Malleability Chosen Ciphertext Attack) secure algorithm can also be used for the challenge response phase between the users authenticating themselves.

  • Automatic detection and classification of safety barriers in road construction sites using a laser scanner
    2009 IEEE Intelligent Vehicles Symposium, 2009
    Co-Authors: Andreas Wimmer, Thorsten Weiss, Francesco Flogel, Klaus Dietmayer
    Abstract:

    Lateral control of trucks is a challenging task, especially in demanding environments such as road construction sites as the lane width is reduced. Detailed and highly accurate maps, which contain Traffic Infrastructure objects, will provide important information for a lane keeping assistant for heavy duty vehicles. This paper presents a new approach for the automatic detection and classification of safety barriers in road construction sites using a laser scanner. This data then is used for the generation of a detailed road work map.

  • Automatic Detection of Traffic Infrastructure Objects for the Rapid Generation of Detailed Digital Maps using Laser Scanners
    2007 IEEE Intelligent Vehicles Symposium, 2007
    Co-Authors: Thorsten Weiss, Klaus Dietmayer
    Abstract:

    Detailed digital maps are of benefit for navigation systems and also for future driver assistant and safety applications. The generation of detailed digital maps is an expensive and time-consuming process as there is much manual rework. In this work, algorithms for the automatic detection of Traffic Infrastructure objects are proposed. The accurate positions of lane markings, sidewalks, reflection posts and guardrails are determined automatically by a vertically and a horizontally mounted automotive laser scanner. The high position accuracy of the mapped Traffic Infrastructure objects allows for the rapid generation of up to date, accurate and detailed digital Infrastructure maps with a cost efficient sensor setup and a low demand for manual rework.

  • Generierung praeziser digitaler Verkehrsinfrastrukturkarten mit Laserscannern / Generation of digital Traffic Infrastructure maps using laserscanners
    2006
    Co-Authors: T Weiss, J Juchler, Klaus Dietmayer
    Abstract:

    Detaillierte und praezise digitale Karten unterstuetzen zukuenftige intelligente Fahrerassistenz- und Sicherheitsapplikationen durch Informationen ueber die umgebende Verkehrsinfrastruktur. Die Generierung solcher detaillierter und praeziser digitaler Karten ist sehr aufwaendig und kostenintensiv. Im Rahmen dieser Arbeit werden Algorithmen vorgestellt, die mit Hilfe zweier Laserscanner, von denen einer horizontal an der Fahrzeugfront und der andere vertikal ueber dem Fahrzeugheck montiert ist, automatisch Verkehrsinfrastrukturobjekte wie Fahrbahnlinien, Leitpfosten, Leitplanken und Gehsteigkanten detektieren und mit hoher Positionsgenauigkeit in eine digitale Karte eintragen. (A) ABSTRACT IN ENGLISH: Detailed digital maps are of benefit for intelligent vehicles and future driver assistant and safety applications. The generation of detailed digital maps is an expensive and time consuming process. In this work algorithms for the automatic detection of Traffic Infrastructure objects such as lane markings, sidewalks, reflection posts and guardrails are proposed. The objects are detected by two laser scanners. One is mounted on the front bumper of the car and provides horizontal distance profiles. Another laser scanner is mounted above the rear of the vehicle and provides vertical distance profiles. With the help of this system the Traffic Infrastructure objects can be registered in a map very accurately.

  • urban Traffic Infrastructure investment and air pollution evidence from the 83 cities in china
    Journal of Cleaner Production, 2018
    Co-Authors: Chuanwang Sun, Yuan Luo
    Abstract:

    Abstract Emissions from heavy urban Traffic have been the most abundant components of urban air pollution in China. Compared to the fast increasing consumption of automobile, the growth rate of urban Traffic Infrastructure investment (UTII) is relative low. It is a controversial issue for the policymaker whether promoting the UTII could make a positive impact on reducing air pollution or not. This study is designed to test the relations between the UTII and air quality, using the data of 83 cities from 2000 to 2012. Based on the empirical results from the fixed effect model and dynamic panel data model, increasing the UTII could generally mitigate the air pollution, but the long-run and short-run effects are significantly different. In the short run, the UTII effect on air quality is −0.02, since the urban Traffic Infrastructure construction might cause more detours and road blockages, which would enhance the fine-particle emissions of the low-speed Traffic. In contrast, the UTII could widen the roads and make the Traffic system more accessible in the long run, so the estimated positive effect is about 0.05. The robustness tests about different regions and scales of cities are conducted. Policy suggestions are further recommended to reduce air pollution.
