PREPARED BY DKS ASSOCIATES Brian Chandler, National Director for Transportation Safety Veronica Sullivan, Transportation Engineer and Planner Sam Garcia-Birginal, Transportation Engineer Caleb Trapp, Engineering Assistant MSI Arc O I ('� Al1)' 1'1 /1\ PAGE 1 1 The City of Pasco is committed to reducing the number and severity of roadway collisions on its city streets. The City has developed this City Road Safety Plan using the framework established in Washington State's Target Zero effort to provide data driven collision reduction strategies on the City's roads. The purpose of the City Road Safety Plan is to analyze crash data in the City in order to effectively identify trends, contributing factors, associated risk factors, and deficiencies present in the City's road network. Following this approach allows for the effective identification of appropriate, low cost countermeasures to be implemented for the purpose of crash reduction. The correlation of crash trends to the associated contributing factors, risk factors, and roadway deficiencies supports efficiency in identifying the need for crash reduction strategies as well as the implementation of specific infrastructure -based countermeasures to reduce the risk of crashes resulting in serious injuries or fatalities. The following plan includes a summary of existing safety conditions in Pasco, identification of safety needs, and recommended treatments to address high-priority collision types and locations. To effectively prevent future collisions on the City's roadways, the City must first understand the history of those collisions and other related sources of potential risk. The Washington State Department of Transportation (WSDOT) provided the following data sets. 1. WSDOT City Safety Summary, 2014-2018 (provided by Ed Spilker, WSDOT Local Programs) 2. WSDOT database of all crashes on City of Pasco Roads, 2014-2018 (provided by Julie Brown, WSDOT Transportation Data, GIS & Modeling) DATA ANALYSIS OVERVIEW As illustrated in Figure 1, over the past 10 years the number of fatal and serious injury collisions in the City has ranged from 4 to 12 crashes annually. After a peak of 12 crashes in 2015 and 2016, that number decreased the following years to 8 in 2018. The general trend since 2009 is a slight increase. The total number of reported crashes per year (regardless of severity) has steadily increased from 519 in 2009 to 860 in 2018 (with a high of 882 reported collisions in 2016). The 5 -year average of 2009-2013 increased 46% to the 5 -year average of 2014-2018.

Common crash types included the following: • 1,159 rear -end crashes (29% of crashes) • 1,087 entering at angle crashes (27% of crashes) • 54 pedestrian -related crashes (1.4% of crashes) o 26 bicycle -related crashes (0.01% of crashes) Collisions within the City of Pasco were typically not severe, though several fatal and serious injury crashes occurred: 7 crashes resulted in fatalities • 43 crashes resulted in serious injuries The five most common driver errors and road user behaviors were responsible for nearly 65% of all crashes in Pasco, including: 1. 1,019 Inattention (26%) 2. 627 Did Not Yield Right -of -Way (16%) 3. 561 Followed Too Closely (14%) 4. 225 Improper Turn or U-turn (6%) 5. 175 Speeding (4%) 6. 141 Alcohol or Drug Use (3.5%) 7. 121 Disregard Stop and Go Light (3%) MEF,ASC-_; i 0f_A[ POAI) SA[ L I Y F[f, d PAGE 6 Fatal and Serious Injury Collisions Figure 4 shows the City of Pasco's most common collision types that resulted in fatal and serious injury collisions from 2014 to 2018. Following is a description of the Top 5 types. 1. Angle (T) was involved in 32% of fatal/serious collision and more than 27% of all collisions. Pasco has 11% more angle (T) collisions than Average Eastside Cities (cities east of the Cascade Range) 2. Hit Pedestrian includes crashes involving a person walking along the roadway or crossing the road. Pedestrian collisions were only 1% of all crashes (regardless of severity), but 16% of fatal and serious injury collisions, which shows the potential for harm in these crashes. 3. Angle (Left Turn) collisions were a part of 10% of all fatal/serious and total collisions. 4. Roadway Departure (Fixed Object and Overturn) contributed to 22% of fatal and serious injury collisions.

Occurring at Signalized Intersections MPAGE 10 Alm I Following WSDOT's recommended procedure,z the City applied the most common risk factors in fatal/serious injury crashes to the entire network using frequency of collisions based on the most common risk factors / collision attributes. The City mapped crash frequency based on the seven most common risk factors in fatal and serious injury crashes. The maps in Appendix A illustrate the locations of crashes with these attributes. Table 2 and Table 3 list intersections and corridors ranked by the number of risk factors / collision attributes identified. A location received a "point" for a risk factor if it experienced a relatively high frequency of crashes with that attribute compared to the rest of the City of Pasco roadway network. An additional point was added if that location was identified as a citizen concern. TABLE 2. INTERSECTION SAFETY NEEDS, PRIORITIZED BY NUMBER OF RISK FACTORS A.

Detailed calculations for each treatment are available in Appendix B. PAGE 14 D i *f N ROAD 28 & W SYLVESTER STREET This intersection is approximately 1,000 ft east of US -395. It is a 4 -leg signalized intersection with continental crosswalks across W Sylvester Street (eastbound and westbound directions) and standard crosswalks across N 281h Avenue (northbound and southbound directions). The northbound approach along N 28th Avenue has a shared through/left-turn lane and a right -turn only lane. The southbound approach along N 28th Avenue has one shared through/left/right-turn lane. The eastbound approach along W Sylvester St has one shared/right-turn lane, one through lane and a 125' left -turn pocket. The eastbound approach also has a 5 -section dog -house signal that allows protected/permissive movements for the left -turning vehicles. The westbound approach has one shared through/right-turn lane and a 125' left -turn pocket where left -turning vehicles must yield on green. Based on vehicle counts taken between June 5, 2018 - June 7, 2018, the average daily volume travelling eastbound and westbound along Sylvester Street was reported 4,257 and 4,410, respectively. Based on vehicle counts taken between September 9, 2018 - September 27, 2018, the average daily volume travelling northbound and southbound was reported 3,668 and 4,942, respectively.

Approximately 290' south of this study intersection is a railroad crossing with a mild curvature along S 10th Avenue at W Columbia St, as shown in Figure 7. It may be beneficial if the City of Pasco were to consider installing a northbound advance signal ahead warning sign that would alert drivers to stop for an approaching red light. 5 loth Ave & W Lewis St: Intersection Countermeasure Seven of the 11 angle crashes at this intersection involved northbound motorists, and a review of the site indicated that another intersection (West Columbia Street), curvature near that intersection, and a railroad track could cause some confusion for northbound motorists. An advanced warning sign indicating the signal ahead could provide additional information for drivers. Connecting a flashing beacon to the signal timing (i.e., flashing only during yellow and red phases for northbound traffic) could increase its effectiveness. PAGE 20 FIGURE 7.

Along the W Sylvester Street corridor there are four signalized intersections (N 10th Avenue, N 14th Avenue, N 20th Avenue and N 28th Avenue) and two pedestrian crosswalks (N 18th Avenue and N 24th Avenue). There are sidewalks on both sides of W Sylvester Street from N 10th Avenue to Road 28. The posted speed limit along this corridor is 35mph, however in a school zone such as the Rowena Chess Elementary School, the posted speed limit is 20mph. Based on the WSDOT Functional Classification Map9, W Sylvester Street is identified as an urban minor arterial and serves as one of the important east -west corridors. TABLE 9.

Due to the large right-of-way width along this study corridor, a potential project to be considered is a road diet, as illustrated in Figure 8. A Road Diet is generally described as "removing travel lanes from a roadway and utilizing the space for other uses and travel modes." io Be, - After FIGURE 8. BEFORE AND AFTER LANE CONFIGURATIONS OF A ROAD DIET IMPLEMENTATION Road Diets are effective at addressing rear -end, left -turn, angle, and sideswipe (lane -changing) collisions. Along W Sylvester St in the study segment, more than 58% (152 of 262) of collisions were of these types. Road Diets can also provide safer conditions for pedestrians by reducing the number of lanes required to cross from 4 to 3. An example of a road diet is shown in Figure 9. FIGURE 9.
