Which factor is NOT a consideration in traffic signal warrant analysis?

In traffic signal warrant analysis, the primary focus is on evaluating the need for a traffic signal based on operational and safety criteria, which include factors such as traffic volume, accident history, and pedestrian activity.

Traffic volume is important because it indicates the level of vehicular and pedestrian traffic that a location experiences, which can necessitate the installation of a signal for safe interaction between different road users. Accident history is analyzed to identify any incidents that may have occurred due to the lack of traffic control, thereby justifying a signal installation to enhance safety. Pedestrian activity is also a critical consideration, as more foot traffic may require a signal to assist and protect pedestrians crossing.

The installation costs of a signal, while an important consideration for overall project feasibility and budgeting, do not directly influence the warrant analysis. Warrant analysis primarily assesses safety and operational needs, rather than financial implications or costs. Thus, this makes the signal installation costs not a factor in the analysis of whether a signal is warranted.
