摘要翻译：
分子马达是利用某种形式的输入能量进行机械功的大分子复合体。这些马达在其上运动的丝状轨道由蛋白质（如微管）或核酸（DNA或RNA）组成。通常，许多这样的电机在同一轨道上同时运动，它们的集体性质与高速公路上的车辆交通有表面上的相似之处。我们开发的模型提供了“统一”的描述：在低密度极限下，一个模型捕捉单个马达的输运性质，而在高密度下，同一模型解释相互作用马达的集体时空组织。通过与车辆交通的类比，我们引入了新的量来表征分子马达在其轨道上的时空组织的性质。我们展示了交通样的细胞内集体现象如何依赖于相应的单个马达的机械化学。

英文摘要：
Molecular motors are macromolecular complexes which use some form of input energy to perform mechanical work. The filamentary tracks, on which these motors move, are made of either proteins (e.g., microtubules) or nucleic acids (DNA or RNA). Often, many such motors move simultaneously on the same track and their collective properties have superficial similarities with vehicular traffic on highways. The models we have developed provide ``unified'' description: in the low-density limit, a model captures the transport properties of a single motor while, at higher densities the same model accounts for the collective spatio-temporal organization of interacting motors. By drawing analogy with vehicular traffic, we have introduced novel quantities for characterizing the nature of the spatio-temporal organization of molecular motors on their tracks. We show how the traffic-like intracellular collective phenomena depend on the mechano-chemistry of the corresponding individual motors.
