      <title>CELLULAR DIGITAL PACKET DATA (CDPD) PERFORMANCE FOR IVHS APPLICATIONS</title>
      <link>https://trid.trb.org/View/494342</link>
      <description><![CDATA[This paper analyzes the capability of cellular digital packet data (CDPD) to provide wide-area Intelligent Vehicle Highway Systems (IVHS) services in a typical metropolitan area.  Delay-throughput performance results are obtained from MOSS (Mobile Systems Simulator) for a representative city- wide cellular deployment.  Both normal peak- period traffic and the case of a major highway incident creating abnormally high localized IVHS data loads are considered.]]></description>

      <title>PACKET-SWITCHED CELLULAR COMMUNICATION ARCHITECTURE FOR IVHS USING A SINGLE RADIO CHANNEL</title>
      <link>https://trid.trb.org/View/494343</link>
      <description><![CDATA[This paper proposes a radio architecture that offers two-way transmission services essential to intelligent vehicle highway systems (IVHS) using only a single (30kHz) radio channel. Within this bandwidth multiple communication services can be supported, including datacasting, packet switched transmission to and from vehicles collection of traffic data from probe vehicles and transmission of emergency messages.]]></description>

      <title>VEHICLE LOCATION AND TRACKING FOR IVHS IN CDMA MICROCELLS</title>
      <link>https://trid.trb.org/View/494344</link>
      <description><![CDATA[This paper discusses the use of mobile cellular radio networks for providing vehicle location information to intelligent vehicle/highway system (IVHS) services.  Automatic vehicle location (AVL) techniques are reviewed in context to their application in a direct-sequence code- division multiple-access (DS/CDMA) system.  A new matched filter location technique which is suited to the CDMA environment is discussed along with simulated error statistics and recommendations for improvement.]]></description>

      <title>MULTIPLE ACCESS AND SPATIAL COLLISION RESOLUTION FOR IVHS PACKET RADIO NETWORKS</title>
      <link>https://trid.trb.org/View/494347</link>
      <description><![CDATA[In this paper, a multiple access and collision resolution scheme that accounts for the spatial aspects of cochannel interference is introduced and analyzed for roadside base station to vehicle packet communications in intelligent vehicle highway systems (IVHS).]]></description>

      <title>SYSTEM PERFORMANCE OF VEHICLE-ROADSIDE COMMUNICATIONS USING ASYNCHRONOUS AND SYNCHRONOUS MAC PROTOCOLS</title>
      <link>https://trid.trb.org/View/494348</link>
      <description><![CDATA[This paper presents the results of a performance evaluation of vehicle- roadside communication (VRC) systems using different medium access control (MAC) schemes proposed for standardization.  The asynchronous protocol proposed within the European standardization group is compared with a synchronous protocol being proposed for the Intelligent Vehicle Highway Systems (IVHS) communication architecture.]]></description>
