217 forecasted level of service, crash rates from 2011 to 2015, freight system, transit 218 service, and pathways. 219 220 Chair Cihacek inquired what a MSA street is. Mr. Culver responded it is a 221 Municipal State Aid street and the City is allowed to spend the dollars it receives 222 from the gas tax on those streets. The roads with higher volumes of traffic are 223 designated a MSA streets, 20 percent of the roads in the City can have this 224 designation, and they can be changed annually, if they City chooses to. 225 226 Mr. Mareck explained the classifications of the roads and their uses. With each 227 use, there is funding and speed and design considerations that are applied to the 228 improvements. The categories of roads are updated with the transportation plan as 229 necessary. Mr. Culver stated that only roads classified as A Minor Arterial and 230 above can receive Federal funding. Mr. Mareck stated Twin Lakes Parkway could 231 be officially designated as a collector road as part of this Transportation Plan 232 update. 233 234 Member Misra inquired about the process for changing the classification of a 235 roadway. Mr. Culver stated any request they make to the Metropolitan Council on 236 a County road would need to have the support of the County. 237 238 Mr. Mareck referred to the map on page 37 of the meeting packet, and reported on 239 the existing average daily traffic. He referred to the legend on the map and 240 explained dark green represents atwo-lane road way, light green represents athree- 241 lane roadway, yellow represents a four -lane roadway without a median, orange 242 represents a four -lane roadway with a center median, and red represents a major 243 expressway. This map includes data from 2012 through 2015. Regarding the two 244 colors on Snelling/Highway 51, people go in different directions, there is more 245 traffic being dispersed onto other roads south of Highway 36, and this is reflected 246 in the numbers. They can go through a modeling analysis to pick out roadway 247 lengths to show where the traffic is coming from and going to. 248 249 Mr. Mareck referred to the map on page 38 of the meeting packet. He explained 250 how the level of service classification relates to the volume to capacity (v/c) ratio. 251 They typically construct most projects to level of service D. Regarding Interstate 252 35W and the differing congestion during different times of the day, they look at an 253 average overall level of service for all lanes together. They are all generalizations, 254 and if they did a detailed study on Snelling Avenue, they would look at the type of 255 traffic on the roadway, the speed of the traffic, volume of the cross streets, and 256 amount of access. 257 258 Mr. Mareck referred to the maps on page 39 and 40 of the meeting packet and 259 highlighted the forecasted 2040 average daily traffic and 2040 level of service 260 classification as it relates to the v/c ratio. The roadways congested today remain 261 that way in the future and the Rice Street corridor is projected to be worse than it is 262 today. These numbers are based on the demographic forecasts from the Page 6 of 11
