Application of New Pedestrian Level of Service Measures SACOG 6. Results of Pedestrian Level of Service Analysis Two pedestrian LOS methods were applied in two case study areas within the SACOG region. The case studies were conducted to assess the level of effort needed to collect data elements required, and to help assess the sensitivity of the two models to various factors. The goal was not to definitively assess pedestrian LOS in either case study area, but to use the case studies to identify which data elements to prioritize for collection for a regional dataset on walking infrastructure in the SACOG region. Although significant help was provided by staff at both agencies in assembling data, the data and results presented below are SACOG’s, and do not reflect the views of either the City of Woodland or the City of Roseville. Woodland Case Study PPM Results Using the PPM model, the segments in the Woodland case study area scored an average of 15.9 points, for an overall study area average of LOS B. The four segments along Main Street scored LOS A. Fifteen segments scored a LOS B, and three segments scored a LOS E. See Exhibits K and L for a complete list and maps of study area segments and their corresponding LOS scores. Appendix C shows detailed scoring tables for each segment in the study area. The four segments of Main Street scored LOS A. The point totals for these segments were only 1‐2 points higher than the segments that scored LOS B, largely due to the fact that the sidewalks on Main Street are 8 feet wide rather than five feet. Also, since Main Street has more employers than most of the LOS B segments, the LOS A segments scored points for having TDM strategies in place. As noted above, the PPM and MMLOS models varied considerably in evaluating the same segments. These differences are discussed below. The segments that scored LOS B are all low‐speed streets with continuous pedestrian facilities/sidewalks that have pedestrian amenities (lighting, shade trees) and a buffer between the street and the sidewalk. It should be noted that “buffer” is defined differently between the MMLOS model and the PPM model. For the most part, these streets have marked crosswalks and curb cuts. However, the segments failed to achieve LOS A because the sidewalks did not exceed five feet, the segments have frequent driveway conflicts, and the area does not always have TDM strategies in place (especially on more residential streets). The three segments that scored LOS E are alleys. These were included to show the variation in scores possible for roadways that do not have pedestrian facilities. Since the PPM model heavily weights wide, well‐maintained, buffered pedestrian facilities, the alleys understandably scored low. Issue Date: June 2011
