Appendix F: Response Sheet

Aquetong/Windy Bush Roads – Road Safety Audit

CORRIDOR WIDE

SAFETY ISSUES	Solution	Decision Agree/Reject	Planned Completion Date	Comments
Drainage
Poor drainage or the lack of a proper drainage system in the corridor has resulted in a number of safety issues. Potentially resulting in sheeting across roadway during inclement weather. Edge of roadway eroded due to wash out. Swells need to be cut back, near S curve east of Sugan Road Pipes are clogged, some are not visible (due to debris)	Conduct a comprehensive drainage study for the corridor to identify specific issues and long term solutions. Consideration should be given to additional pipes and new parallel drainage systems. In the short term: clean clogged pipes and remove debris from the drains. In addition, where possible excavate and fill in with ballast (rocks).
Edge Lines and Edge Drop-offs
Lack of edge of pavement delineation is consistent through the corridor. In addition, edge drop offs are consistently evident. This is a result of the poor drainage control.	Install edge line as appropriate throughout the corridor to guide motorists and prevent run of the road crashes. PennDOT should consider minimum 9.5 foot lanes as a safety measure
Fixed objects
Numerous fixed objects were observed in the clear zone. These included trees (large and small); boulders (many used for landscaping by property owners and, stone headwalls (approx. 3 feet above the ground)	All fixed objects in the clear zone should be removed. Initial clearing should be at least four feet from edge of travel. Many trees along the corridor were already marked for removal
Narrow roadway width
Roadway width throughout the study area on Aquetong and Windy Bush Roads varied between 9 and 10 feet	All fixed objects in the clear zone should be removed. Initial clearing should be at least four feet from edge of travel. Many trees along the corridor were already marked for removal
Vegetation
Trees and shrubs obstruct the view of many signs throughout the corridor and interfere with sight lines	Trimming trees and brush
Centerline Delineation
The corridor is shadowed during the day due to the canopy of trees and extremely dark at night, a result of the lack of street lighting. Coupled with narrow pavement width.	Install raised pavement markers (RPM) the length of the corridor to keep the motorist in his travel lane. Installation of centerline rumble strips to assist in the prevention of cross-over head-on collisions were examined but the narrowness of the travel lanes negates this treatment.
Speed Limit
Given the geometry of the corridor, the set speed limit of 45 MPH may be excessive	A speed study was conducted by PennDOT; as a result, the speed limit will be lowered along Aquetong Road from River Road to Sawmill Road to 35 MPH
Passing Zones
There are too many passing zones in the corridor given the narrow lanes and edge drop offs which are not forgiving if motorist overcompensate while passing.	Eliminate passing zones
Signs
No “Share the Road” signs. Construction signs located along Aquetong Road with no construction being conducted No name plates for advance intersection signs	Install “Share the Road” signs throughout the corridor so motorists are cognizant of other users. Remove or cover construction signs at times when there is no work being conducted on the roadway. Add street name plates to advance intersection signs Add advance signs for hidden driveways as appropriate
Pavement Markings
Several intersection approaches with stop control do not have stop bars	Install stop bars to intersection approaches as appropriate Many trees along the corridor were already marked for removal
Sight Lines
Limited sight lines	Maximize sightlines around curves by cutting back embankment and removing trees.

SPECIFIC LOCATIONS

SAFETY ISSUES	Solution	Decision Agree/Reject	Planned Completion Date	Comments
At Covered Bridge Road
Covered Bridge Road is skewed at the intersection with Aquetong Road. Additionally, there are no pavement markings at the Covered Bridge Road approach.	Use pavement markings to soften skew allowing easier access to Aquetong Road especially for left turning traffic
Utility pole to the west of the intersection on Aquetong Road obstructs sight lines.	Relocate utility pole
Rail fence west of intersection on Aquetong Road next to parking lot is in Right of Way.	Relocate fence outside Right of Way. Fence will be removed as part of new development
At Rockwood Path
Tree to the west of the intersection blocks sight lines for Rockwood Path approach traffic	Remove tree
Between Rockwood Path and Wagner Road (private road)
“Curve ahead” (W1-2) sign is too far from the actual curve and is faded	Upgrade sign (W1-2) and relocate closer to curve
“Slow Curve Ahead” pavement markings are too far from curve and are wearing out	Add pavement marking legend closer to curve and repaint existing ones.
Eastbound “No Passing” (W14-3) sign knocked down	Replace sign (W14-3)
Hidden driveway at the curve	Install advance warning sign for driveway.
Night time driving difficult due to the darkness which could makes negotiating the curve difficult.	Install lighting on curve
Illegal speed limit sign is installed within the ROW eastbound before the curve	Remove sign
Between Wagner Road (private road) and Old Windy Bush Road
Junction sign is blocked by tree limbs	Trim tree limbs Relocate street name sign to the post assembly of “Stop Ahead” (W3-1) sign
Cut off sign posts are protruding out of the ground	Remove parts
At Old Windy Bush Road
“Stop Ahead” sign is blocked by vegetation	Trim vegetation
At Windy Bush Road
Sign clutter, potentially confusing to motorists	Remove or consolidate signs as appropriate
Westbound approach to intersection, poor sight distance which is made worse by vegetation	Cut away vegetation to improve sight distance
Northeast, northwest and southwest corners of intersection has unprotected drainage holes that lead to pipe	Install protective grates
Windy Bush Road between Old Windy Bush and Aquetong Road
“Intersection ahead” sign on northbound side of the road is blocked by vegetation	Trim vegetation
No advance street name sign for the Aquetong Road intersection	Install advance “Aquetong Road” sign (W16-8)
Old Windy Bush Road at Windy Bush Road
Drainage hole on the southeast corner	liminate passing zones
Utility pole lying on the ground at the southeast corner of the intersection.	Remove pole
Between Windy Bush Road and Sugan Road
Aquetong Road is an S-curve in this area with post mounted warning signs only	Add “Slow Curve Ahead” pavement markings in both direction
Vegetation on the westbound side of the road conceals the edge of pavement	Cut back vegetation
Edge drop off in this section of roadway is pronounced as a result of poor drainage	Currently a PennDOT project to excavate and fill with rocks. This is a temporary fix and in the long term proper drainage should be installed including pipes
Reflector poles are in poor condition. Reflector strips have been stripped from the poles and many are down in the drain	Replace with chevrons (W1-8)
Aquetong Road westbound curves while Sugan Road continues straight ahead,	Add graphic directional signage with road names
At Sugan Road
At Sugan Road the intersection is on the curve and very wide. Additionally, travel lanes are not delineated	Add dashed double centerline and single edgeline through intersection. This will alleviate driver confusion
Curve needs to be delineated	Add large warning arrow (W1-6) on the curve for eastbound Aquetong Road traffic
Between Sugan Road and Solebury Mountain Road
Oversized drainage pipes installed by property owners at driveways are unprotected hazards in the clear zone. Some pipes include headwalls.	Install appropriate drainage pipes according to regulation.
Windy Bush Road between Aquetong Road and Pidcock Creek Road
Open pipe culvert on the side of the road result in unprotected curb drop off.	Widen road to 12-foot lanes with paved shoulder to eliminate open pipe culvert that parallels the road.
Property owners have installed a variety of drainage pipes and sizes at driveways. They are unprotected hazards in the clear zone and some pipes include headwalls.	Install appropriate drainage pipes according to regulation.
Pipes at property owners driveways are clogged with debris	Clear pipes to prevent flooding on the roadway
Guide rail needs to be updated	Replace guide rail with upgraded end treatments.

Title of Report: AQUETONG/WINDY BUSH ROADS - ROAD SAFETY AUDIT

Publication No.: 07042A

Date Published: October 2007

Geographic Area Covered:
The study area includes sections of Aquetong Road (SR 1003) and Windy Bush Road (SR 232) in Bucks County, Pennsylvania.

Key Words:
Road, safety, audit, potential, fatalities, injuries, reportable, crashes, issues, strategies, coordination, engineering, enforcement, education, prioritize, intersection, speed limit, traffic volumes, PennDOT, stakeholders, audit team, curve, sight distance, clear zone, geometry, pavement markings, signs.

ABSTRACT: This is a documentation of the process and findings of the Aquetong/Windy Bush Roads Road Safety Audit (RSA) undertaken by Delaware Valley Regional Planning Commission (DVRPC) in conjunction with Pennsylvania Department of Transportation (PennDOT). The RSA was done on August 17, 2007. The goal of the audit is to generate improvement recommendations and countermeasures for roadway segments demonstrating a history of, or potential for a high incidence of motor vehicle crashes. The emphasis is placed on identifying low cost, quick turnaround safety projects to address the issues where possible. The roadways studied are identified in the Safety Plan for PennDOT District 6. This corridor is located in a suburban environment with numerous curves and steep gradient. Much of the roadway is covered by the canopy of trees which in many instances are located in the clear zone and presents a potential hazard to road users.
