• 1. Study Purpose

Current evaluation is a planning study only Consider all other Previous and Ongoing Studies, including:

MIIF MD 214 and MD 468 Crossroad Improvement project Mayo Peninsula Parks TIS

Provide a safe and efficient connection for all travel modes while minimizing impacts to private property and the natural & built environment

Schools

Mayo Elementary AM queuing Summit School Access

Parks/Marinas

Weekend traffic impacts

AM Queuing on Mayo Ridge Road 7

• 2. Existing Conditions – Primary Findings

Limited gaps for traffic turning onto MD 214 during peaks, particularly in the western portion No pedestrian/bike facilities Substandard horizontal curves Limited sight distance at select intersections Police Reported Crashes decreasing or remaining constant year to year

• 2. Existing Conditions – Traffic

Volumes increase East to West Westbound MD 214 queue extends from MD 468 to Loch Haven Road during AM peak Few gaps for side street traffic to turn onto MD 214 Queuing on Mayo Ridge Road associated with Mayo Elementary School 2018 Average Daily Traffic (ADT) on MD 214:

9 20,950 15,850 10,900 6,800 3,100

• 2. Existing Conditions – Speeds

Speed study – measured at 7 points along MD 214

40 MPH Posted Speed West of Turkey Point Road

85th percentile speed ≈ 46 MPH

30 MPH Posted Speed East of Turkey Point Road

85th percentile speed ≈ 38 MPH

Highest instances of speeding - late night/early morning hours

• 2. Existing Conditions – Bike, Ped, Transit

No pedestrian/bicycle infrastructure Bike LOS E at most locations Low pedestrian and bicycle activity No transit on MD 214

12

7/17/2018

• 2. Existing Conditions – Police Reported Crashes

13

74% of crashes occurred at or west of Loch Haven Road 1 fatality between MD 468 and Loch Haven Road

Pedestrian struck at night

Rear End and Fixed Object most common types Number of crashes decreasing or remained constant year to year

• 2. Existing Conditions – Drainage

14

Open Section Roadway

Some Side Ditches Cross Culverts

Drainage Issues

No Hydraulic Analysis Performed Ponding Observed Undersized Culvert East of River Club Drive (Reed Property SWM Report)

• 2. Existing Conditions – Sight Distance

Sight distance measured at all named streets (40 locations)

AASHTO standards not met at 12 intersections (30%)

Primary sight limitations due to:

Roadside vegetation (public and private property) Fences (private property) Roadway curvature Signage (public & private)
