4 <br />Determining the appropriateness of enhanced crossing infrastructure requires a thorough review of <br />the crossing location. The following steps are guidance for using or reviewing this process. Each <br />crossing location requires staff review and engineering judgement beyond the basic guidelines <br />included in this chapter and must include context-specific solutions beyond the scope of this <br />document. Ideally this process is completed during the roadway design process, however, in many <br />cases review occurs after the roadway is built or a new facility is added. This process is intended to <br />help guide the reviewer through a methodical and data driven process such that engineering <br />judgment can be effectively applied. <br />1. Performing field review and preliminary data collection to understand existing conditions <br />and potential issues. Preliminary data collection includes existing, easily accessible data that <br />is expected to take the reviewer less than 30 minutes and will determine if the crossing is <br />acceptable for additional review performed by steps 2, 3, and 4. <br />2. Collect data to complete the review using recommended data points included in the Data <br />Collection Form. The process includes the following steps: <br />a. Identify crossing location. <br />b. Collect roadway geometric and configuration data. <br />c. Collect traffic and operational data. <br />d. Collect multimodal data. <br />3. Evaluate the point of crossing using the flowchart and perform a high-level review to <br />understand if a location is appropriate for consideration of an enhanced crossing. <br />4. If the flowchart leads to the conclusion that the consideration of an enhanced crossing is <br />appropriate, continue to engineering review which includes the following steps: <br />a. Review traffic volumes to determine proper roadway configuration/number of lanes. <br />b. Determine if roadway geometric treatments are appropriate. <br />c. Evaluate crossing infrastructure enhancements. <br />d. Conduct specific warrant analyses or review of grade separation feasibility if applicable. <br />1. FIELD REVIEW AND PRELIMINARY DATA COLLECTION <br />Upon identification of a crossing location by preemptive review (e.g., future development, etc.) or <br />reactive evaluation (e.g., community input, recent crash, etc.), initial field review should be <br />completed. This first step will aid in determining if an issue(s) is/are present, if other mitigation <br />measures can be performed external to the process defined by this assessment, or if no additional <br />follow up is necessary. Staff time and capacity is understood to be limited, and this will ensure that <br />only crossings with the highest estimated need are provided the level of review described in the <br />following sections.
