Craver Road Study

UNC Charlotte February 24, 2010

Project Description

• Student Union opened August, 2009
• Vehicle/Pedestrian conflicts in front of

Student Union due to excessive pedestrian volumes

– Safety issues for pedestrians – Traffic flow issues for vehicles along Craver Road

Student Union Crossing

Student Union Crossing

Project Description

• Two Analysis Scenarios

– Short term solution: installation of traffic/pedestrian signal at Student Union crossing

• How will a signal work at this crossing? For

vehicles? For pedestrians?

– Long term solution: closure of Craver Road to non-essential through traffic

• How can closure be implemented? What effects

will closure of Craver Road have on the rest of campus?

Data Collection

• Three Peak Periods

– 7:00 AM – 9:00 AM – 10:00 AM – 1:00 PM – 4:00 PM – 6:00 PM

• Traffic Counts at 5 study intersections
• Pedestrian Counts at Student Union
• Video Data
• Wednesday November 18th, 2009

• Synchro 7
• SimTraffic
• Sidra Intersection 3.2
• Based on HCM Methodology

Existing Traffic Volumes

Volume Adjustments – Craver Road Closure

• Service Vehicles [Counted]
• Drop-off Traffic [30% of Remaining Trips]
• Source/Sink Traffic [10% - West End of

Craver Rd., 30% East End]

• Diverted Trips

– Video data – pseudo origin-destination study to attempt to determine travel patterns

Existing Traffic Volumes With Closure

Future Campus Growth

• Future analysis year of 2015
• In referring to Master Plan and anticipated

campus growth, a compound annual growth rate of 3% was used

Recommendations

• Cameron Boulevard and Phillips Road /

Craver Road

– Signal at existing Phillips Road intersection expected to work well and increase safety – Future signal at proposed re-alignment of Phillips Road with Craver Road expected to work well

• Northbound and southbound left turn lanes

recommended on Cameron Boulevard

Recommendations

• Craver Road Improvements

– Signalization of Student Union Crossing expected to work well

• Low cycle length
• Pedestrians as main line

– Craver Road Closure concept drawing

• Provides closure with access for University

vehicles

• Would fit within current infrastructure
• Pedestrian friendly
• Construction cost estimate - $780,000

Recommendations

• Cameron Boulevard and Mary Alexander

Road

– Long delays/queues as expected with Craver Road Closure as unsignalized intersection – Roundabout and Signalization both adequate solutions – Roundabout concept drawing

• Provides adequate capacity
• Would fit within current infrastructure
• Attractive entrance to campus
• Construction cost estimate - $340,000
