Subtask 10 Review peak hour movement forecasts with SDDOT and City. Graphics showing the movement forecasts were delivered to SDDOT on 4/3/10 for distribution and review. Subtask 106 Create study area operations models and analyze existing conditions. Operations models were created and Interstate and arterial operations were analyzed. Summaries of the operations analysis results are shown in Tables 1-4. The analyses indicate acceptable Interstate mainline levels of service, with all segments operating at LOS A or B under 010 conditions. Likewise, the Interstate ramps and weave locations operate at LOS A or B under 010 traffic conditions. The 010 arterial intersection levels of service for the study area intersections are also acceptable, ranging from LOS A to C. Analysis outputs are provided in the Appendix. Subtask 107 Update models for future year No Action conditions and repeat analysis. The operations models were updated with the future year traffic forecasts and the operations analysis was repeated, with results shown in Tables 1-. A number of Interstate mainline segments were seen to fall to LOS C by 030, but all segments remained within the acceptable range. All the Interstate ramps remained within acceptable levels of service in 030, except the eastbound I-90 off ramp at Haines Avenue, which operates at LOS F. Interstate weave sections continue to operate at acceptable level of service through 030. Arterial intersection levels of service are acceptable through 030, except the intersection of Disk Dr./Haines Ave., which operates at LOS D in the 030 PM peak hour.

Subtask 108 Crash analysis. Crash data for the study area was provided in a geo-referenced database, displayed in ArcGIS format. The GIS allowed display of crash locations on top of a study area map and easy identification of crash clusters and potential crash problems needing improvements. Overall, the Interstate system showed randomly scattered crashes, with two exceptions the I-90/I-190 interchange area and the weave area on eastbound I-90, between I-190 and Haines Avenue. Figure 10 Crash display I-90/I-190 interchange area The I-90/I-190 interchange area (Figure 10), showed a slight concentration of crashes, but analysis of the crash records showed no trend toward any particular type of crash. Rather, crashes appear to be related to operating on hills and curves during winter driving conditions, as well as a number of animal-related crashes. No particular road-related remedy is suggested, although continued attention to winter maintenance may help control crash rates. The crash rate for the eastbound I-90 segment between I-190 and Haines Avenue (Figure 11) appears fairly high, although the rate may be skewed by the short length of the segment. Review of the crash details shows that 83% of the crashes occurred in inclement driving conditions. Again, continued attention to winter maintenance may help control crash rates. Interstate segment crash rates are shown in Table 6. Engineering, Inc.

The critical crash rate that triggers improvement can vary from community to community and year to year, depending on the statistical analysis of crash rates from a large population of intersections. While the small number of intersections in this study do not permit calculation of a critical crash rate, arterial intersection critical rates in South Dakota usually range in the vicinity of 0.80 1.0 crashes per million entering vehicles. This would point toward the following intersections as potential candidates for improvement: Omaha St./West Blvd./I-190 Omaha St./ th St. Engineering, Inc.

North St./Mt. Rushmore Rd. Haines St./I-90 Haines St./Disk Dr. Since this study is limited to a small number of arterial intersections, it was possible to review the crash records for each intersection to look for trends and indications of potential problems. The crash location display for each intersection is shown starting on the following page, along with a short summary of the findings.

Omaha St./West Blvd./I-190 A total of 7 crashes were reported in three years (007, 008, 009). Over 7% of the crashes were rearend, while over 18% were angle crashes. The crash display indicates that many of the crashes are occurring after vehicles have crossed the stop-bar and entered the intersection. This suggests that rear-end crashes may be occurring due to downstream congestion and downstream merging. Some potential countermeasures may include: Downstream acceleration lane for southbound to westbound right turn. Check peak hour queues on southbound West Boulevard. Check lane marking for double left turn lanes to reduce vehicles drifting into others paths. Engineering, Inc.

Omaha St./Mt. Rushmore Rd. A total of 8 crashes were reported in three years (007 009), split primarily between rear-end (0%) and angle (3%) crashes. Crash locations are scattered around the intersection, although a concentration may be developing related to the westbound to southbound left turn. No other trends were noted or improvements suggested. Engineering, Inc.

Omaha St./ th St. A total of 7 crashes were reported in three years (007 009), split primarily between rear-end (7%) and angle (1%) crashes. The majority of the crashes appear to be occurring in the center of the intersection in line with left turn lanes. It is possible that some of the rear-end accidents are occurring due to downstream congestion, perhaps related to railroad operations in the vicinity. Engineering, Inc.

UI-190/West Blvd./Silver St./North St. A total of 13 crashes were reported at this location, but 6 of the 13 were single-vehicle crashes actually on I- 190 in inclement weather conditions. Seven of the 13 were listed as intersection-related. There were an insufficient number of crashes to establish trends or suggest crash-related improvements. Engineering, Inc.

Mt. Rushmore Rd./North St./Allen St. A total of 10 crashes were reported in three years (007 009), split primarily between rear-end (30%) and angle (60%) crashes. The intersection is currently operating with all-way stop control. Intersections of this type typically have a slightly higher critical crash rate than larger signal-controlled arterial intersections. It appears that the crash rate at this intersection may not be critical and that the majority of the crashes are related to driver difficulties in determining right-of-way. The location does not currently meet the number of crashes necessary to warrant conversion to a traffic signal, but conditions should continue to be monitored in the future. Engineering, Inc.

Haines Ave./ th St./North St. A total of 1 crashes were reported in three years (007 009), split primarily between rear-end (7%) and angle (67%) crashes. Most of the crashes were related to drivers failing to yield or not obeying the traffic signals. No other trends were noted and the crash rate does not appear to be critical. No crash-related improvements were suggested. Engineering, Inc.

I-90/Haines Ave. A total of 40 crashes were reported in the interchange area in a three year period (007-009). A large portion of the crashes (43%) occurred during inclement driving conditions and it appears that a significant number involved single-vehicle incidents on I-90. A cluster of rear-end crashes appears to be developing in the southbound lanes of Haines Ave., south of the interchange. One potential cause for this cluster may be the interaction of vehicles trying to turn left onto Knollwood Dr. The intersection influence areas of these two intersections appear to overlap, making it difficult for drivers to react in time to avoid collisions. While Knollwood Drive serves businesses and residences fronting I-90, safety concerns may require rerouting Knollwood traffic in the future. Engineering, Inc.

Haines Ave./Disk Drive A total of 31 crashes were reported in the three reporting years (007-009). They were comprised primarily of rear-end (4%) and angle (48%) crashes. Failure to yield citations were prevalent in the crash records, indicating that some drivers may be using the yellow, all-red and red portions of the turning phases to continue to turn under congested conditions. The intersection crash rate may not reach the critical threshold in a city-wide statistical analysis, but operations at the intersection should be reviewed as development continues and volumes rise.
