Second, the pedestrian area in the commercial centre has to grow, which would make this part of the town more pleasant for walking and would improve the opportunities for the shops.

second 是序数词，表示"第二"，用于列举事项时表示顺序。 pedestrian 来自拉丁语 pedester（步行的），指"步行者"或"步行相关的"。 area 指"区域、范围"，在这里指特定的功能区域。 pedestrian area 指专门为行人设计的区域，即"步行区"，通常禁止车辆通行以保障行人安全和舒适。
