UCZ-CA-2: State Highway 39, Orange County, California Corridor characteristics include: Two through-lanes in each direction of travel with a transition to 3 through-lanes per direction briefly. At the location with two lanes per direction there is also a wide right should for most of the segment that develops into right turn lanes as needed for the numerous driveways along this corridor, On-street parking periodically provided but most of the longer cluster-crash regions were at high speed locations where parking was prohibited, No exclusive bicycle facilities, Curb and gutter present for corridor length, Land use is commercial with a little residential (mostly multi-family) mixed n, Road horizontal geometry generally straight, Road vertical grade generally level, Posted speed limit ranges from 35 to 50 mph, Bus stops located far-side, Sidewalk ranges from curb-attached to buffer separated, Utility poles, street lights, and other objects located within 2 to 3 ft of curb face for a large portion of the corridor, and Corridor includes street furniture (benches, trash cans, trees) periodically. Corridor diagnosis for cluster roadside crashes: Several locations where driveways or intersections have street furniture, poles, and trees located immediately beyond the far side of the driveway (in direction of travel), Several mid-block corridor locations with trees, utility poles, and street light poles located inches from the curb, It is worth noting that the poles placed in close proximity to the curb shifted to the opposing side of the road in the middle of the corridor and a clear shift in roadside crashes to that direction of travel is visible. 5

UCZ-CA-3: State Highway 74, Orange County, California Corridor characteristics include: Two through-lanes in each direction of travel with turn lanes (as needed) on west end (milepoint 0.1 to 1.2) transitioning to one through-lanes in each direction with turn lanes (as needed) on east end (milepoint 1.2 to 1.6), No on-street parking, No dedicated bicycle lanes, Land use is primarily residential very few driveways (most located on minor roads that intersect SH 74), Road horizontal geometry generally straight, Road vertical grade generally level, Posted speed limit ranges from 40 to 45 mph, No apparent bus stops on corridor, Sidewalk has a serpentine configuration with a landscape buffer ranging from 0 ft to approximately 8 ft, Street trees located along sidewalk (often on both sides), Utility poles located near road adjacent to uneven terrain only on the extreme east end of project. Corridor diagnosis for cluster roadside crashes: Crashes occurred where trees were located within 4 ft of the curb face on the outside of horizontal curves but similar tree placement at tangent locations did not result in similar crashes, Uneven roadside terrain with no curb and gutter and with utility poles located 10 ft to 12 ft from road at east end (north side) only, The most frequently hit objects along this corridor were curb, trees, and traffic signs followed by signal and utility poles, walls, fences, and other unidentified objects. 11

UCZ-CA-4: State Highway Route 75, San Diego County, California Corridor characteristics include: Two through-lanes in each direction of travel with a median for length of corridor (median on north end heavily landscaped with palm trees and other ornamental landscaping), On-street parking periodically provided along north end, No bicycle lane, Land use is commercial, tourism, & military, Road horizontal geometry generally straight on south end with sharper horizontal curvature on north end, Road vertical grade generally level, Posted speed limit ranges from 25 to 55 mph, Bus stops located in wide striped shoulder region on east side of road, Sidewalk with landscape buffer on north end, shared use facility toward south end, Utility poles, street lights, and other objects located within 2 to 6 ft of curb face, and Corridor includes street furniture (benches, trash cans, trees) periodically. Corridor diagnosis for cluster roadside crashes: Median palm trees 4 to 6 ft from back of curb were visibly scarred from being impacted by vehicles. The locations where the palm trees were set back further did not encounter this problem. The specific location with the palm trees closer to the road also had the most extreme horizontal curvature along the corridor. At the south end of the corridor there was a wide shoulder, higher speed limit, and a narrow island (approximately 6 ft wide), with a shared use facility on the far side. This region experienced several fixed object crashes. Objects at this location were frequently spaced light standards with concrete bases constructed in the narrow raised island. For the southbound direction of travel, several crashes occurred immediately adjacent to the Coronado Hotel area. At this location there is a small rigid wall located just beyond a narrow sidewalk on the outside of a horizontal curve. It is worth noting that unfamiliar drivers could be observed visibly tapping their brakes at this location as they looked at the historic hotel. For the southbound direction of travel at the southern end of the study region, the speed limit increases at the same time as the curb and gutter is replaced by a wide paved shoulder. At this same location there is a tall rigid wall located approximately 15 to 16 ft from the edge of the shoulder. The most frequently hit objects along this corridor were curb, barrier or guardrail followed by signal poles, posts, trees, walls, and embankments. 14

UCZ-CA-5: State Highway 76, San Diego County, CA Corridor characteristics include: Two through-lanes in each direction of travel with a median on west end changing to three lanes in center then transitioning back to two, then one lane per direction of travel towards the east end of corridor, On-street parking not permitted, Bicycle lane available length of corridor with turn lanes and wide shoulder located on far side of bicycle lane, Curb varies from rolled asphalt curb at extreme west end, to raised curb near intersections, to sloping curb at most non-intersection locations, Land use is commercial, Road horizontal geometry generally straight, Road vertical grade level to rolling while roadside grade is extreme in several locations, Posted speed limit 55 mph entire length, No bus stops available, Sidewalk periodically available with some locations designed as a concrete v-ditch for drainage options, Utility poles, street lights, and other objects located within 2 to 3 ft of curb face near intersections and then placed further away from road mid-block, and No street furniture except for periodic trees or gateways into adjacent property. Corridor diagnosis for cluster roadside crashes: Extreme roadside terrain next to sloping curb beyond 10 ft shoulder source of several crashes including fatalities. At many locations there are steep changes (downgrades) in terrain just beyond the sloping curbs and trees are located at the base of these sideslope areas. Roadside crashes occur at lane merges (just beyond intersections). At these locations there are common urban roadside elements including light poles located within approximately 4 ft from the curb. 17

UCZ-CA-7: State Highway 90, Orange County, CA Corridor characteristics include: West end has two through-lanes in each direction of travel with turn lanes as needed at intersections expanding to three through-lanes in each direction for milepoints 4.0 to 8.0 (note: four-lane section has wide striped shoulder in front of curb used to develop right turn lanes), On-street parking not permitted, No separate bicycle facilities, Land use is commercial with periodic driveways, Road horizontal geometry generally straight with two to three horizontal curves, Road vertical grade generally level to rolling, Posted speed limit ranges from 35 to 50 mph (one 0.2 mile 25 mph school zone), Bus stops located far-side and mid-block, Sidewalk is curb-attached from milepoint 3.0 to 6.0, then separated with a landscape buffer from 6.0 to 8.0, Utility poles, street lights, and other objects located within 1 to 2 ft of curb face, and Corridor includes street furniture (benches, trash cans, trees) periodically. Corridor diagnosis for cluster roadside crashes: Locations with utility poles plus street lights located in the curb-attached sidewalk and within 1 to 1.5 feet from the curb face were common roadside crash sources both on tangents and at horizontal curve locations, The far side of intersections and several driveways (particularly in the eastbound direction) have poles located in the immediate vicinity. Many appear to have been impacted by vehicles. A far-side bus bay with a driveway then merges traffic back into the normal lane configuration for about 10 ft before beginning a right turn lane. At this location a pole is in the merge point. Several crashes occurred here but it is not clear if they were due to the roadside obstruction or driver confusion thinking this was the right turn lane for the upcoming intersection and/or driveway. 24

Corridor diagnosis for cluster roadside crashes: The placement of utility poles is the primary problem along this corridor. For two sections of the corridor there appears to be a beautification program including pole relocation and (on the far south end) placement of power underground. At these locations the roadside crash problem improved except for one location where ornamental street lights were located along a stretch of blanket driveways. Elsewhere poles are within inches of the road and have been hit in both tangent and horizontal curve locations. This includes poles at intersection and driveway far side locations. 45

UCZ-IL-2: Route 14, Cook County, IL Corridor characteristics include: Two through-lanes in each direction of travel with a median or TWLTL for most of the study corridor, No on-street parking provided, No separate bicycle facilities provided, Land use is commercial with minor residential and industrial at extreme corridor ends, Road horizontal geometry generally straight, Road vertical grade generally level, Posted speed limit ranges from 30 to 40 mph (with 20 mph school zone), Bus stops not obvious, Sidewalk not continuous but is curb-attached in general with some buffer strips present, Utility poles, street lights, and other objects located within 2 to 3 ft of curb face in some areas, and Corridor includes street furniture (benches, trash cans, trees) periodically. Corridor diagnosis for cluster roadside crashes: Large number of crashes into concrete median. Two types of medians are present a small median at intersection approaches with traffic signs and an access management median (extremely narrow) at the west end of the corridor. Both medians are hard to see as the curb faces are not painted and the physical design of both medians is small. Several crashes involved traffic signals (this was the second most frequently hit object) while islands (third most frequently hit item) were also impacted. At many of these locations, the signal pole is in the directional island at an intersection. Other common objects hit included light standards, poles or posts, and utility poles. At one location a cluster of these crashes occurred when pole placement shifted from a 5 to 6 ft offset down to a 1 to 2 ft offset (in a straight section of road). In addition to the objects listed above, common impacted fixed objects included mailboxes, trees, undefined roadside objects, impact attenuators, ditches or embankment, guardrail ends, and other misc. items. 52

UCZ-IL-3: Route 19, Cook County, IL Corridor characteristics include: Two through-lanes in each direction of travel with a periodic median for most of the study corridor narrowing to 3 lanes (1 EB and 2 WB) then to 2 lanes only at the east end of the corridor, On-street parking periodically provided, No exclusive bicycle facilities provided, Land use is commercial but a nature preserve is located between milepoints 3.6 and 4.7 (thus a higher posted speed limit), Road horizontal geometry generally straight, Road vertical grade generally level, Posted speed limit ranges from 30 to 45 mph, Bus stops located far-side, Sidewalk varies from curb-attached to separated by a buffer strip, Utility poles, street lights, and other objects located within 2 to 3 ft of curb face in some high crash locations, and Corridor includes street furniture (benches, trash cans, trees) periodically. Corridor diagnosis for cluster roadside crashes: Cluster pole crashes (utility poles, light standards, and traffic signal poles) occurred generally where poles were within 1 to 2 ft of the curb face or near driveways or pedestrian access ramps at intersections. In general, trees were located on the far side of sidewalks and rarely hit; however, in some locations trees were located closer to curb (within 1 to 2 ft in eastbound direction) and frequently hit at these locations. In addition to the poles and trees identified above, the most frequently hit objects were mailboxes, curb or island, fences, other (unidentified objects), and the concrete median. 57

UCZ-IL-4: Route 19 (DuPage County) Corridor characteristics include: Two through-lanes in each direction of travel with a median or TWLTL for most of the study corridor narrowing to two lanes total periodically, On-street parking periodically provided, No exclusive bicycle facilities available at this site, Land use is commercial and residential, Road horizontal geometry generally straight, Road vertical grade generally level, Posted speed limit ranges from 30 to 45 mph, Bus stop locations not obvious, Sidewalk is not continuous and treatment varies, Utility poles, street lights, and other objects located within 1 to 3 ft of curb face in cluster crash locations, and Corridor includes street furniture (benches, trash cans, trees) periodically. Corridor diagnosis for cluster roadside crashes: Cluster pole crashes (utility poles, lights, posts, and railroad or traffic signals) occurred generally where poles were with a 1 to 2 ft of the curb face or 8 to 10 ft of lane edge where curb was not present. Other locations with curb had pole placement 4 to 6 ft from the curb with very few mid-block pole crashes. This corridor did not have much landscaping in the commercial areas. At the residential areas trees were generally more than 10 ft from the road. A small landscaped buffer appeared periodically but only 5 trees were hit in the corridor due to their sparse placement with generally acceptable lateral offsets. In addition to the poles, signals, posts, and trees referenced above, common fixed objects included curb or island and mailboxes followed to a lesser degree by buildings or structures, other unidentified objects, and ditches or embankments. 60
