AQUETONG/WINDY BUSH ROADS - ROAD SAFETY AUDIT1.0 BACKGROUND This is the first Road Safety Audit (RSA) of Phase II, of this two-phased program. In fiscal year 2007 (PRSAs were conducted in three different environments – urban, suburban and rural. The work is now befiscal year 2008 in which several RSAs will be conducted. This project represents the coordination of tRegional Planning Commission’s (DVRPC) Planning Work Program and Pennsylvania Department of (PennDOT) District 6 Safety Plan. DVRPC’s planning work program includes a RSA Program. All state transportation are required to develop a Strategic Highway Safety Plan (SHSP) in order to draw on safto SAFETEA-LU, the federal transportation legislation. In Pennsylvania each district is required to have be incorporated in the state’s SHSP. In PennDOT’s District 6 Safety Plan several corridors are identifie148 Planned Safety Projects eligible for Highway Safety Improvement Program funding. This was an oanalyze corridors which were already on the plan and eligible for dedicated funding. Whereas, the goal of this project is to improve and promote transportation safety on the region’s roadwmaintaining mobility, the main objective is to address the safe operation of the roadway and ensure a h

for all road users. The road safety audit program is conducted to generate improvement recommendatcountermeasures for roadway segments demonstrating a history of, or potential for a high incidence of 

crashes. The emphasis is placed on identifying low cost, quick turnaround safety projects to address thpossible but will not exclude the more complex projects. 1.1 The Audit Prior to the road safety audit activities on site, DVRPC collected, reviewed and analyzed data (video o

different conditions, traffic volume data, turning movement counts, maps, aerial photographs, previous crash data). Using the crash data, crash clusters were identified and mapped for locations along AqueBush Roads. These locations were the main focus of the road safety audit. The Road Safety Audit was conducted on Friday, August 17, 2007. The Pre-Audit meeting involved the safety audit and how it differs from a corridor study process; the required steps of an audit; presentatioissues and an exchange of ideas and knowledge of the roadway. A video showing the corridor under nwas also shown. The field view involved the audit team which was made up of federal, state, and local stakeholders walking the corridor and identifying transportation safety problems. See Appendix A for t

members. The post-audit meeting was spent discussing the findings from the field view and determinin

1.2 Overview of the Study Area The study area consists of 1.8 miles of Aquetong Road (SR 1003) from Covered Bridge Road to Soleband 0.4 mile of Windy Bush Road (SR 232) from Aquetong Road to Cornwell Drive in Solebury Townssee Appendix B for Study Area Map. At the request of PennDOT the audit team also looked at Windy Aquetong Road to Pidcock Creek Road. Aquetong Road is functionally classified as a rural major colleBush Road and an urban collector west of this point. This road runs in a north-west to south-easterly dBush Road is functionally classified a rural major collector south of Aquetong Road and an urban colleAquetong Road. The land use in the corridor is predominantly residential with large lot single family hospots of commercial and institutional uses. The area is distinctly suburban and rural in character. Aquetong Road has two lanes throughout its length, one travel lane in each direction with no shoulders roadway consists of numerous curves and steep grades; with no sidewalks. Windy Bush Road has two its length, one travel lane in each direction with narrow shoulders. There are six unsignalized intersectAquetong Road within the study corridor with a 4-way stop at Windy Bush Road and a 2-way stop at thintersection. Traffic volumes in the corridor vary. Volumes collected this summer showed that there are higher volumRoad east of Windy Bush Road than west. This is consistent with volumes collected in the late 1990s aThe 2007 volumes registered AADT of 2,370 vehicles between Covered Bridge Road and Rockwood Pvehicles just east of Solebury Mountain Road. An AADT of 2,398 vehicles were recorded on Windy BuOld Windy Bush Road and Cornwell Drive. This is consistent with the 1995 volumes. The speed limit a45 MPH with curve warning speed limit of 25 MPH. 1.3 Crash Data According to PennDOT’s crash data there were 25 reportable crashes between 2003 and 2005. Repocrashes which may result in a fatality, injury and/or property damage rendering the vehicle disabled, refrom the scene. A comprehensive analysis of the crash data is shown in Appendix C. Of the reportabwere 16 crashes in 2003 (64%); 2 crashes in 2004 (8%); and 7 crashes in 2005 (28%). When analyzinby month, February had the highest number of crashes with 5 (20%), April was next with 4 crashes anSeptember had 3 crashes each. The months of March, June and October had no reportable crashes re

2.0 FINDINGS AND RECOMMENDATIONS The following represents the findings and recommendations of the Aquetong/Windy Bush Roads Road CORRIDOR-WIDE ISSUES 

SAFETY ISSUES REMEDIAL STRATEGIES LEVEL OF EFFORT 

o 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 

High 

Drainage o 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. 

o Edge of roadway eroded due to wash out. o Swells need to be cut back, near S curve 

east of Sugan Road 

o Pipes are clogged, some are not visible 

(due to debris) 

o In the short term: clean clogged pipes 

and remove debris from the drains. 

o In addition, where possible excavate 

and fill in with ballast (rocks). 

Low 

Medium 

Edge Lines and Edge Drop-offs o 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. 

o 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

Low 

Fixed objectso 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) 

o 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

Medium 
Aquetong/Windy Bush Roads – Road Safety Audit Report 

 

SAFETY ISSUES REMEDIAL STRATEGIES LEVEL OF EFFORT 

Narrow roadway width o Roadway width throughout the study area 

on Aquetong and Windy Bush Roads varied between 9 and 10 feet 

o Any widening of the roadway may 

require additional right of way. Given the roadway geometry travel lanes should be at least 12 feet wide in the 40 MPH zone with a shoulder width of at least 2 feet. 

High 

Vegetation o Trees and shrubs obstruct the view of 

many signs throughout the corridor and interfere with sight lines 

o Trimming trees and brush Low 

Centerline Delineation o 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. 

o 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 crossover head-on collisions were examined but the narrowness of the travel lanes negates this treatment. 

Medium 

Speed Limito 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

Low 

Passing Zones o 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. 

o Eliminate passing zones Low

Signs o No “Share the Road” signs. o Construction signs located along 

Aquetong Road with no construction being conducted 

o No name plates for advance intersection 

signs 

o Install “Share the Road” signs 

throughout the corridor so motorists are cognizant of other users. 

o Remove or cover construction signs at 

times when there is no work being conducted on the roadway. 

o Add street name plates to advance 

intersection signs 

o Add advance signs for hidden 

driveways as appropriate 

Low Low Low Low 

Pavement Markings o Several intersection approaches with stop 

control do not have stop bars 

o Install stop bars to intersection 

approaches as appropriate 

Low 

Sight Lines o Limited sight lines 

o Maximize sightlines around curves by 

cutting back embankment and removing trees.

3.0 CONCLUSIONAs discussed earlier, the road safety audit program is conducted to generate improvement recommendcountermeasures for roadway segments demonstrating a history of, or potential for a high incidence of crashes. The safety issues identified during the audit and documented in this report along with recommshould improve the overall safety of Aquetong and Windy Bush Roads. These remedial strategies can time and budget limitations permit. The study area is identified under PennDOT’s Section 148 Planned and therefore, implementation is eligible for Highway Safety Improvement Program funding. Additionalstrategies identified can be implemented through routine maintenance. Given that the contributing factors for some crashes are “running the stop sign” and “too fast for condit

strategies alone cannot effectively address the traffic safety issues identified along the corridor. Therefand education are necessary components to address the human behavioral aspects to effectively reducrashes occurring.

Response Sheet 

Aquetong/Windy Bush Roads – Road Safety Audit

CORRIDOR WIDE

SAFETY ISSUES Solution Decision Agree/Reject Planned Completion Date 

Drainage o 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. 

o Edge of roadway eroded due to 

wash out. 

o Swells need to be cut back, 

near S curve east of Sugan Road 

o Pipes are clogged, some are 

not visible (due to debris) 

o 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. 

o In the short term: clean 

clogged pipes and remove debris from the drains. 

o In addition, where possible 

excavate and fill in with ballast (rocks). 

Edge Lines and Edge Drop-offs o 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. 

o 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
SAFETY ISSUES Solution Decision Agree/Reject Planned Completion Date 

Fixed objectso 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) 

o 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 o Roadway width throughout the 

study area on Aquetong and Windy Bush Roads varied between 9 and 10 feet 

o Any widening of the 

roadway may require additional right of way. Given the roadway geometry travel lanes should be at least 12 feet wide in the 40 MPH zone with a shoulder width of at least 2 feet. 

Vegetation o Trees and shrubs obstruct the 

view of many signs throughout the corridor and interfere with sight lines 

o Trimming trees and brush 
SAFETY ISSUES Solution Decision Agree/Reject Planned Completion Date 

Centerline Delineation o 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. 

o 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 Limito 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 o 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. 

o Eliminate passing zones 
SAFETY ISSUES Solution Decision Agree/Reject Planned Completion Date 

Signs o No “Share the Road” signs. o Construction signs located 

along Aquetong Road with no construction being conducted 

o No name plates for advance 

intersection signs 

o Install “Share the Road” 

signs throughout the corridor so motorists are cognizant of other users. 

o Remove or cover 

construction signs at times when there is no work being conducted on the roadway. 

o Add street name plates to 

advance intersection signs 

o Add advance signs for 

hidden driveways as appropriate 

Pavement Markings o Several intersection 

approaches with stop control do not have stop bars 

o Install stop bars to 

intersection approaches as appropriate 

Sight Lines o Limited sight lines o Maximize sightlines around 

curves by cutting back embankment and removing trees.
