Traffic from New Development
• Traffic volumes in the corridor would increase by average of 5% based on Build-out conditions
• Similar growth pattern: from Albany Shaker Road to Old Niskayuna Road via Maxwell Road/Osborne Road
• Exit 4 connector, west of Wolf Road and increased capacity on I-87, will not increase traffic on Maxwell Road and the corridor east of Maxwell Road

Traffic from New Development
• Likely increase in traffic due to development will progress slowly over time and will not have immediate impact
• Based on the CDTC STEP Model 40% of the traffic is cut-through

Safety: Speed
• Posted speed limit is 40 mph• Average speed is 35 mph• 85th percentile speed is 45 mph• Peak hour speeds: Near Shaker El 36/34 mph (AM/PM) Near Twilight Terrace 40/30 mph (AM/PM)
• High residential use-traffic conflict index (CDTC) leading to noise level, driveway movement, unsafe environment

Safety: Speed
Mitigation• Reduce speed limit to 30
or 35 mph • Increased speed
enforcement• Driver feedback signs
![Page 21: Albany Shaker Road Corridor Study · 2017. 11. 16. · •Traffic volumes in the corridor would increase by average of 5% based on Build-out conditions •Similar growth pattern:](https://reader036.vdocuments.site/reader036/viewer/2022063010/5fc2a7349c773b6500236396/html5/thumbnails/21.jpg)
Safety: Speed
• Higher the speed, reduction in cone of visibility• Risk of serious injury increases dramatically
above 30 mph
30 MPH 40 MPH
NACTO Street Design Guidance
Recommend speed reduction to 30-35 mph
![Page 22: Albany Shaker Road Corridor Study · 2017. 11. 16. · •Traffic volumes in the corridor would increase by average of 5% based on Build-out conditions •Similar growth pattern:](https://reader036.vdocuments.site/reader036/viewer/2022063010/5fc2a7349c773b6500236396/html5/thumbnails/22.jpg)
Safety: SpeedData shows that driver feedback signs are effective• In Shelburne, Vermont, radar speed feedback signs
showed a reduction in speed by 6 to 8 mph• On US Route 9 in the Town of Malta, CDTC found that
the driver feedback signs resulted in a 5 mph reduction in average speed
Recommend installation of driver feedback signs

Side Street Traffic
• Consider traffic calming measures on alternate routes to discourage regional traffic from using local/neighborhood streets Street design Education Enforcement
Locations to Consider: Campagna Drive/Marie
Parkway Emerick Ln/Briarwood Road Danielwood Drive Loudon Parkway

Coordination with other Studies
• The Town is in the middle of update to the Comprehensive Plan and an update to the Airport Area GEIS
• Expected to be completed before completion of the Comprehensive Plan and the Airport Area GEIS
• It is expected that the Comprehensive Plan will either keep projected development densities at current levels or lower them through the Comp plan and future land use law changes. These changes should not influence the results of the ASR Study.
