- 2. Transportation Impact From thedawn of civilization, transportation has been the defining force in economic progress. The earliest settlements were concentrated along the great navigable waterways of the world, and trails and trade routes determined commerce for millennia. Over time, railroads, highways, and, more recently, airports have been added to the infrastructure complex of the world. As at the beginning, modern economies are defined by accessibility and logistics, and superior transportation offerings are a critical factor in the competitiveness and success of a region. Dr. M. Ray Perryman, March 21, 2016 2

Editor's Notes
- #2 Open remarks – to be prepared by presenter for each occasion
- #3 I know these words are too small for you to read, so I am going to read it for you because Dr. Ray Perryman recently summed up our need rather well: read slide
- #4 Just follow slide
- #5 Follow slide
- #6 It is worth looking around us to find examples. When you look at Dallas and Tarrant Counties, what stands out are the networks of “limited access roadways” (LARs), also called “controlled access facilities”, also called freeways and tollways. So let’s compare the networks in Dallas and Tarrant Counties to Collin County
- #7 It is very clear how many more LARs there are in Dallas and Tarrant Counties than in Collin County.
- #8 So, how did Dallas County develop that network? There was a report in the Dallas Morning News in 1957 that showed a map of the network at that time plus some proposed additional roadways. So these roadways were developed a long time ago. It is interesting to look at the population of Dallas County around that time: 1950 census = 614,799 1960 census = 951,527 Ironically in 1957, Dallas County’s population was very similar to Collin County’s today
- #9 Look at how few LARS there are in Collin County and how few are planned!
- #10 As we all know, traffic is already building. Let’s look at two examples: US 380, west of US 75; and SH 78 just west of SH 205. Generally the capacity of a 6-lane thoroughfare is considered to be about 36,000 vehicles per day for a reasonable level of service. As you can see, part of US 380 has already surpassed that and SH 78 is well on its way. The projections for 2035 are far above the capacities in both cases.
- #11 Follow slide
- #12 When slide comes up, it will just have the title: “Strategic Planning” – this is the narrative to go along with that: The County has initiated a process of Strategic Planning and we are encouraging all of the transportation agencies operating in the County to join us. First click brings up the first line – just make that statement Second click brings up the next line – ask that question
- #13 When the slide comes up, it will have the title and the first bullet, which is the first answer to the question on the previous slide. This point is VERY IMPORTANT! First click will bring up second bullet – just state what is on the slide
- #14 The first bullet will be on the slide when it comes up – these are continuation of answers to the question of the steps for planning strategically: We need to partner with ALL the transportation agencies in Collin County develop a long-term master plan – based on projections for when the County is “built-out” First click will bring up second bullet: We have seen enough of the projections to know that the task is going to seem impossible. We feel it will require all agencies partnering together to determine what has to be done.
- #15 First bullet will come up with slide: So, let’s take a lesson from Dallas County planning in and before the 50s First click brings up second bullet: Let’s identify first the backbone of the mobility plan
- #16 On February 1, 2016, the Commissioners Court had a lengthy discussion about this subject and decided to set some priorities for their efforts. They dealt with Limited Access Roadways - LARS
- #17 When the slide comes up, the title, map and “LARs” will be on the slide: “The Court discussed the corridors that are projected to have the worst congestion and identified these roadways as needing to be LARs and set the following priorities for their planning and funding: First click, No. 1: US 380, throughout the County Second click, No. 2: SH 78 from the County line to US 380 Third click, No. 3: A North-south LAR between US 75 and Lake Lavon to relieve US 75, connecting from north of McKinney to the Pres George Bush Turnpike Fourth click, No. 4: The Outer Loop from the Denton County line to US 75
- #18 Most of our conversation about mobility is about relieving congestion. But won’t the amount of congestion we have in the county have an impact on our County’s economy?
- #19 We have long been heavily dependent on what we call major thoroughfares – 4-lane or 6-lane divided thoroughfares. And we work hard for years to get these funded and built. These are important and have their place. But think a minute with me about what you observe about developments on thoroughfares and LARs. Thoroughfares generally support retail and commercial that support the local area (with some exceptions, of course).
- #20 Limited access roadways generally support larger, regional commercial development – like this.
- #21 Or this
- #22 When the slide comes up, it will have the title and the first two lines in white: We need to answer a very important question – now. First click: Collin County has been fortunate so far to have developed in such a way that a very strong “economic engine” has resulted that benefits all the areas of the County. Will the factors that allowed the creation of that economic engine continue or will it grind to a halt?
- #23 When the slide comes up, only the title will appear: So that is the picture, as we see it: the needs and the impacts. So what are our next steps? First click: We have engaged a consultant to develop traffic projections for the “build-out” condition. We feel those are very important to quantify the size of the challenge. Those projections are almost completed. Second click: Once we have those projections and we can see precisely where the problems are, we need to develop a process in which all of the transportation agencies can work together to determine what to do about these challenges.
- #24 The cities and the County have to agree where the LARs should go in order to maximize larger commercial developments as opposed to neighborhood service commercial.
- #25 It is imperative that we find routes NOW through our fast-growing county in order to preserve the ROW.
