| 摘要： | Current methodologies for the in-service performance evaluation (ISPE) of roadside safety features are not viable and practical for all state departments of transportation. The research team developed an ISPE process that is sensitive to the data and resource constraints of TxDOT. The following methodology was used to develop the TxDOT-ISPE process: identify the objectives of the ISPE, estimate expected extent of data collection, evaluate existing DOT procedures and organizational structure, identify features to be included in the ISPE, develop framework for an ideal ISPE, identify system constraints within the DOT, identify alternative methodologies and data sources for the ISPE, design a DOT-specific ISPE process, design and conduct a pilot test of the ISPE, evaluate the data collection methodology and data quality during the pilot test, and recommend an ISPE process for TxDOT. |
