ge roadway network, with existing roadway capacities. As the figure shows, the area where demand exceeds capacity is in the commercial and industrial core of the City. T.H. 10 is deficient through the entire length of the downtown district. Another significant problem area is Proctor Avenue north from T.H. 10, through the intersection with School Street and northwest along County Road 1 to the Elk River Industrial Park, and School Street east from the Proctor Avenue intersection to Jackson Avenue. T.H. 169 is deficient from the T.H. 10 interchange north to Main Street, as in County, Road 13 from Tyler Street to the T.H. 169/Main Street intersection. Upland Avenue is deficient from T.H. 10 north to Meadowvale Road, and although it doesn't appear on the map, Meadowvaie Road has the potential for congestion from Upland Avenue west to 192nd Avenue. Other isolated problem areas are on Jackson Avenue and School Street, both to the west from T.H. 169, and Main Street west from T.H. 10 to downtown Elk River. These areas identified as deficient are roadway segments where forecasted travel demand exceeds existing roadway capacity in an all-or-nothing ultimate assignment. They are not guaranteed to be the only problem areas as the City grows, but they are the most likely areas for congestion to develop. Remedial Actions In this section, each roadway segment that is deficient in the ultimate development travel demand forecast is examined individually to identify improvements within the right-of-way that will likely be necessary. This is followed by descriptions of proposed additions to the roadway network and their impact on the remainder of the network. As a general introductory note, when the issue of congestion on a roadway comes up, the first place to look is its intersections. Traffic will generally flow smoothly on any roadway segment if there are not interruptions. The addition of access points, on-street parking, lane drops, etc. can have serious adverse effects on traffic flow. But intersections are the most critical features affecting traffic movement on a roadway. Improving traffic control and channelization at intersections will often do more to increase roadway capacity than any other measure. This is particularly true when two congested roadways intersect. a. Improvements to Existing Roadways Trunk Highway 10 Ultimate travel demand forecasts suggest that T.H. 10 will become an extremely high volume arterial, with ADT's well over 50,000 through the central business district. Aside from increases in thru traffic, there are two primary internal causes for the heavy volumes: the filling in of areas zoned commercial in the CBD, and a large increase in commercial/industrial trip generation in the southeast comer of the City. T.H. 10 is currently accessed nearly every block between Upland Avenue and Main Street. Many of these intersections will -24- CTP-230.156 230-156-80
