      <title>CONGESTION ON MULTILANE HIGHWAYS</title>
      <link>https://trid.trb.org/View/664127</link>
      <description><![CDATA[This paper presents a new model for traffic on multilane freeways. The model incorporates both equilibrium curves and a simple switching mechanism that allows cars to transit from one equilibrium curve to the other. This switching mechanism, when combined with the continuity equation, produces relaxation or self-excited oscillations in the system, and these oscillations are the focus of the research conducted herein.]]></description>

      <title>A RIGOROUS TREATMENT OF A FOLLOW-THE-LEADER TRAFFIC MODEL WITH TRAFFIC LIGHTS PRESENT</title>
      <link>https://trid.trb.org/View/646104</link>
      <description><![CDATA[This paper models traffic flow on a unidirectional roadway in the presence of traffic lights. Individual car responses to green, yellow, and red lights are postulated and these result in rules governing the acceleration/deceleration of individual cars. The model's essence is that only specific cars are directly affected by the lights. The other cars behave according to simple follow-the-leader rules that limit their speed by the spacing between them and the car directly ahead. The model has many desirable properties; namely, cars do not run red lights, do not smash into one another, and exhibit no velocity reversals. In a situation with multiple lights operating in-phase, after an initial start-up period, a constant number of cars through each light during any green-yellow period is noted. Moreover, this flux is less by 1 or 2 cars per period than the flux obtained in discretized versions of the idealized Lighthill-Whitham-Richards model which allows for infinite accelerations.]]></description>

      <title>WAVE BREAKDOWN AND TURBULENCE</title>
      <link>https://trid.trb.org/View/34958</link>
      <description><![CDATA[The phenomenon of wave breakdown is defined as the onset of a violent small-scale secondary instability developing on a large-scale primary disturbance of wave-like traveling type.  It is suggested that breakdown together with the ensuing violent mixing process (a turbulent "burst") constitutes the dominant nonlinear mechanism for the fluctuating velocity field in a turbulent boundary layer. A burst regeneration mechanism is proposed whereby one breakdown can excite large velocity defects in the shear flow which then may trigger a new breakdown, thus leading to self-maintenance of the turbulence.]]></description>
