Before thinking about implementing new transportation services, it is essential to assess the performances of the available ones and to develop an objective diagnosis of the adequacy between transportation supply and demand. This paper focuses on the refinement of a spatial–temporal clustering process able to encapsulate the spatial distribution of travel demand and supply. It illustrates the potential of such process to assist in the development of an objective diagnosis of the quality of the configuration of transit services. The two tools composing this process are presented in this paper, Traclus_DL and Grille_CR. A literature review is conducted on the main concepts such as corridors and grids, which will give a better understanding of the contributions proposed in this paper. Traclus_DL is a spatial clustering algorithm for desire lines (direct line from origin to destination) developed by Bahbouh. This paper will explain how this algorithm works and will also present improvements that were implemented to facilitate its usage and to give a better representation of the reality. Grille_CR is an automated smoothing tool which facilitates the visualization and the interpretation of the results produced by Traclus-DL. This paper explains how this process can be implemented and illustrates its relevance for public transport analysis and design. The major contribution of this paper is the implementation of a tool which helps better understand the spatial configuration of the demand in transport.

在考虑实施新的运输服务之前，必须评估可用服务的性能，并对运输供需之间的平衡进行客观诊断。本文着重于时空聚类过程的细化，该过程能够封装旅行需求和供给的空间分布。它说明了这种过程在协助发展对运输服务配置质量的客观诊断方面的潜力。本文介绍了构成此过程的两个工具Traclus_DL和Grille_CR。对诸如走廊和网格之类的主要概念进行了文献综述，这将使人们更好地理解本文提出的贡献。Traclus_DL是由Bahbouh开发的用于需求线（从起点到目的地的直线）的空间聚类算法。本文将解释该算法的工作原理，还将介绍已实现的改进，以促进其使用并更好地表示现实。Grille_CR是一种自动平滑工具，可以方便地可视化和解释Traclus-DL产生的结果。本文解释了如何实施此过程，并说明了其与公共交通分析和设计的相关性。本文的主要贡献是工具的实现，该工具有助于更好地了解运输需求的空间配置。本文将解释该算法的工作原理，还将介绍已实现的改进，以促进其使用并更好地表示现实。Grille_CR是一种自动平滑工具，可以方便地可视化和解释Traclus-DL产生的结果。本文解释了如何实施此过程，并说明了其与公共交通分析和设计的相关性。本文的主要贡献是工具的实现，该工具有助于更好地了解运输需求的空间配置。本文将解释该算法的工作原理，还将介绍已实现的改进，以促进其使用并更好地表示现实。Grille_CR是一种自动平滑工具，可以方便地可视化和解释Traclus-DL产生的结果。本文说明了如何实施此过程，并说明了其与公共交通分析和设计的相关性。本文的主要贡献是工具的实现，该工具有助于更好地了解运输需求的空间配置。本文解释了如何实施此过程，并说明了其与公共交通分析和设计的相关性。本文的主要贡献是工具的实现，该工具有助于更好地了解运输需求的空间配置。本文解释了如何实施此过程，并说明了其与公共交通分析和设计的相关性。本文的主要贡献是工具的实现，该工具有助于更好地了解运输需求的空间配置。
