在这篇文章中的结果被描述，已经发现，当解决问题的分配员工到他们的工作场所（目的地分配），通过使用一个真正的微观的方法，其输出是适合于微观交通模拟。本文用交通规划的重力效应的微观随机模拟来处理这一问题。然而，旅行目的地的计算只是模拟步骤序列中的第一步。其输出将用于计算基于模拟的动态交通分配（路线分配），从而得出任何旅行者从家到工作所需的旅行时间。这些旅行时间将用于进一步的重新分配步骤，在该步骤中，旅行时间超过一定限度的任何旅行者都将被重新分配新的工作地点（目的地）。这将创建一系列的重新分配和重新路由过程，其结果将在本文中报告。结果表明，本文提出的方法能够微观地描述目的地和路径选择。
In this article the results are described that have been found when tackling the problem of the assignment of employees to their working places (destination assignment) by using a truly microscopic approach, whose output is suitable for a microscopic traffic simulation. This problem is dealt with a microscopic stochastic analogue of the gravity ansatz of transportation planning, described in this article. However, the computation of the travel destinations is only the first step in a sequence of simulation steps. Its output will be used to compute a simulation-based dynamic traffic assignment (route assignment), resulting in travel times needed from home to work for any traveler. Those travel times will be used in a further reassignment step, where any traveler whose travel-time has exceeded a certain limit is subject to re-assigning a new working place (destination). This creates a sequence of re-assignment and re-routing processes, whose results will be reported in this article. The results obtained show that approach presented in this article is capable of describing the destination and route choices microscopically.
