PROVINCIAL ROAD (PR) 200 ― St. Mary’s Rd South Perimeter to Courchaine Rd

Presented by: Raylza Campos, Johassen Cestina, Paula Cruz, Marc Tablan

• Provide a basic description of both the current transportation system (T), the current activity system (A), and the flow system (F)

• Conduct a travel time and delay study for your segment • Predict future flow conditions based on historical data • Identify two key operational challenges that affect traffic operations on the segment

• Provincial Road 200 is a secondary high way adjacent to PTH 75 and the Red River

• PR 200 spans from South Perimeter to the CAN-US border • Study segment is 3.83 km • Two-lane undivided roadway classified as a Collector A • Paved roadway with 1.2-metre shoulders

Actual AADT

Forecasted AADT (compound model) g = 8.51%

Forecasted AADT (linear model)

Forecasted AADT using Winnipeg's population growth rate

Historical AADT

Forecasted AADT (compound model) g = 4.90%

Forecasted AADT (linear regression) slope = 125.42

Forecasted AADT using Winnipeg's population growth rate (compound model) g = 0.83%

• The segment runs parallel with PTH 75 • Courchaine Rd closed until February 2014

due to construction at the Inlet Control Structure of the Red River Floodway

• School bus depot and garden centres • Winnipeg Area Travel Survey is not accurate

for this road • Duff Roblin Provincial Park will act as a

staging area for the Duff Roblin Trail • Class B1 ― Spring weight restrictions

Flow

• Coverage count station located midway • The flow pattern is a TPG1 • Classified as LOS B (reasonably free flow, speed

limited by traffic and number of lanes)

AADT Forecasting

• Compound model using historic AADT (g = 4.90 %)

• Compound model using Winnipeg’s population growth rate (g = 0.83 %)

• Linear model using regression (M = 125.42 veh/yr)

1. Turning radius for buses when the driver is going from St Mary’s Road to the Perimeter Highway or vice versa

2. Difficulty of cars pulling over is an operational challenge as well

Quantitative and Qualitative data

• There are no traffic control points in the segment • We traversed the path six times, three in each direction • Slight operational (traffic) delay during one sample run • Mean travel time determined was 3:03.7 minutes

Link and Network Properties

• Few houses and local roads with direct access • Courchaine Rd links PR 200 to PTH 75 but is closed

Types of vehicles using the road system

• Mostly small and average-sized passenger vehicles • Most recent truck traffic count is 320 trucks per day

The different operating policies

• Posted speed limit of 80 km/h which increased to 90 km/h • Sign advising to watch the road in case of animal crossing

Roads are constructed to attend human expectations, so if a unexpected situation happen on the road, the driver will be able to respond quickly to the situation. Particularly, on St Mary’s Road if the driver is surprised by a situation and needs to pull over, the risk of an accident increases since the shoulder is not designed for this kind of situation. One solution for this problem is to amplify the shoulder of the road and make it flatter.

• Implement rumble strips • Construct a passing lane to allow vehicles to pass slower or

stopped traffic that are making left turns • Re-pave the road to further improve driving conditions • Flatten shoulders and increase shoulder widths • Construct guard rails on the superelevated curve located SB

before Courchaine Rd
