As indicated in the Collision Data Available, Requested, and Received section in Chapter 3, failure to do so often leads to incorrect reporting of incidents, resulting in the need to undertake significant data cleaning before databases can be used for analysis. Categories of Information Included in Accident Reports The accident report forms reviewed by the research team contained several categories of information that were common to many of the forms.

The safety equipment information contained on the incident report forms included traffic controls at intersection; aspect of signals at time of crash; type and condition of switch; visibility and functionality of traffic signs/signals; presence, visibility and functionality of grade crossing devices; type of traffic lines; and presence, type, and indication of transit signal. Most incident forms included only a few of the above listed factors.

All SSO agencies interviewed for this study expressed interest in a consistent standard for accident data collection. FTA/NTD Data The National Transit Database is "the Federal Transit Administration's primary national database for statistics on the transit industry" (National Transit Database Federal Transit Administration 2008 Safety and Security Reporting Manual)

71 Standardized Electronic LRT Incident Reporting To ensure that data relevant to assessing the safety of transit systems and impact of safety treatments are available, it is critical that these data should be consistently collected during the incident reporting process. Since incident report forms are the primary source of information used by transit agencies in incident investigation, site-specific conditions such as the rightof-way classification and the presence or absence of traffic controls, signage, and other safety devices should be consistently reported in the incident report forms used by transit agencies.
