Intelligent Transportation Systems (ITS) & Traffic Signals – Saeed Sohbi & Nitin Deshpande

Published by Darron Toy on

all right thank you very um great to be here to talk to you about this program this morning not the last presentation between you and lunch so that's that's good I'll be sharing the presentation with Nitin Deshpande who is our traffic signal and that metering program manager as many of you know last year when the division of transportation management and operation T's Moe came about that recommendation was made and a traffic signal program was created back in February we brought meeting to lead that that program for us so he is going to take over from me and talk more specifically about the traffic signals portion of ideas and is that at that point then signals became part of the ideas assets objectives the first three is fly flies I will be stepping back a bit and telling you about what the program consists of what assets we manage and what services we deliver using those assets and then I get into an overview of you know who maintains the assets what tools we used and what process we go through to select projects for capital replacement so first what is intelligent transportation systems it is application of advanced technology to solve transportation problems it is all about mobility and safety as director Hunt said this morning it's about getting the most out of the existing transportation system and gas where ideas becomes an integral part of that data strategy ideas strategies usually have high rates of return on investment benefit cost ratios of fifteen to one or twenty to one are quite common in in investments in ideas the features the main components of the ideas system one is the traffic management centers these are the nurse sent nerve centers of the system this is where command and control takes place many of you have been to the traffic centred traffic operations center or ctmc in golden that's the main hub we also have traffic cooperation centers in Hank and hanging lake and either horizontal tunnel many of the local agencies also have their own traffic management centers with whom we integrate and work really closely together another big component or feature of the IT system is the communication backbone and electronics and the network gear that runs that communication backbone that's how we bring all the devices together back to the teo system manager if you go to the TOC many of you have been in addition to the operations floor where operators are behind that is a big room full of these network you're worth millions of dollars that's the brains that that's running the system then the next feature or component is devices that we have on the road these are our eyes and ears where we collect information and disseminate information to the travelers ITES has a long history of using public public or public-private partnerships to expand or maintain the system we rely heavily on these partnerships from you know maintaining and operating our traffic signals or to maintaining and operating our almost 900 miles of fiber-optic system we rely heavily on those and we get a lot of benefit out of that just to give you an example out of a public-private partnership that we have for fiber and i-70 we get hundreds of thousand dollars only in cash that goes back into the maintenance of this system we get a lot of professional services and we get maintenance of the whole line on i-70 so we really heavily rely on these partnerships in addition to those we have a lot of agreements operational agreements related to different things such as instant management law enforcement and data sharing that brings all of this together and makes it work so using this infrastructure and the component that is just talk to you about what services do we provide we provide travel information you are familiar with code trip five one one the mobile app that we started about three years ago Amber Alerts and and many other services that go out to the public traffic management these are where we actually manage traffic using signals and RAM meters smart work zones and these are just some of the examples continuous flow metering for those who are familiar with i-70 operations probably the first time in the nation is a this type of application where we are actually putting mirrors and on the mainline interstate to manage traffic through the tunnel in addition ites is a main component of many of the other larger projects for example the peak period shorter lanes that's being built on i-70 the ATM project on us 36 these are the cannot happen without ideas being an integral part of that traffic incident management is another service that we provide and many different things in that area I don't want to read all of those but that's another area of service from ideas and then the last thing again going back to the fiber optic communication being such an integral part of everything that we do in ideas so moving into what what major assets are in ideas I have listed some of the major ones these are not the only ones but every one of them is integral and so important to how IPS is delivered some of the detection devices that you may not even see on the and the bigger devices like VMs they are equally important to the operation of the whole system the total value of our assets is sitting at about seven hundred and fifteen million dollars that's including the new assets the signals that have been added to ideas who maintains these assets is the IDS branch we have a maintenance group that is mainly stations in Denver but also we have stepped in in other regions reasons themselves participate heavily in maintaining the IITs assets and then a lot of signals or states to the staying in the regions except for region one and we also like I said we heavily rely on public and private partnerships for the maintenance of our assets how do we do this how do we asset management for IT s three components of it I'll talk about one is where we have our asset inventory the asset inventory for IITs is in SAP the only teen will talk about signals and they are a bit different in in our asset inventory we have a lot of information that that's quite useful for us we have a specific notation we can code work to the specific device that's being maintained we have ownership and maintenance responsibilities age and and many other pieces of information in addition we use SAP in order to do work orders and manage maintenance activities that information those two bullets then informs the capital replacement process how we select projects that we defined our funding requirements and define our priorities so we use aims as a tool to give us you know recommendations based on age and maintenance history but in addition to that we use other inputs from regions or technology and maintenance experience in order to make a final decision as to what becomes part of the program for a given year this slide is a graphical version of what I just said so we start with SAP being where the inventory is and Eames giving us recommending recommendations based on age and and maintenance history however there are a lot of other things we want to be you know cognizant about the condition of devices there is structural integrity a major you know specific thing about IT s is technology a lot of times we will have to replace IT systems not because they necessarily reach their defined end of useful life but because we run out of technology the technology doesn't integrate into our system anymore and I can give you many examples of those another component that comes to play in this process is risk ok age is the main target but where what are the main risks and how do we bring that into consideration as we prioritize our project list so that ends up becoming you know including that amount of funding that we have results in a priority list for our projects where are we going with ideas ideas will continue to be an integral part of our strategies for operation of our system and but like I said it is about application of technology in transportation as technology changes ideas is going to change I have shown you a couple of areas that we are currently working on one that the first two have to do with connected vehicles this is what big part of what variety s is going and we are currently involved in the national level getting into this area this is where vehicles communicate to each other or vehicles and infrastructure talk to each other in order to deliver safety and mobility you serve you know specified a couple of example and their vehicle to vehicle and vehicle infrastructure also another area that you will see continued to be very significant in how we do business is multi-agency connectivity we are bringing and a major addition to our system to our operating system which will allow us to manage major events disasters accidents across organizations so these are areas that you will see we will continue to focus on things that I would like for us to take away from this again is that ideas is about application of technology in solving transportation problems and it is a key component of our strategies for transportation system management and of operations total assets are sitting at about 715 million dollars or organizations that are involved in maintaining these assets our largest branch to regions and public-private partnerships and that we manage our assets in s AP and signals are in MLS and with that I turn it over to Nadine to talk more specifically about traffic signals I'd like to begin with kinda explaining why traffic signal asset management is important traffic signals are invaluable tools for the safe and efficient movement of vehicles and pedestrians a structural or functional failure opposes a significant safety risk to the traveling public traffic signal asset management allows us to track infrastructure needs and also track our confident level performance in today's technology heavy environment an asset management system also allows us for the effective and efficient allocation of labor material equipment our resources I would also like to bring your attention that see that has made significant investments in traffic signal systems currently we have approximately 1,900 traffic signals with a replacement value of 500 million dollars this program is pretty new Mercedes nation I started in February early March and I wanted to give you spent few minutes to give you an idea of the future region of this program the FHWA the real-time system management information program I call it a rule requires state deities to designate labs of significance basically or primarily major arterial corridors and make available certain information such as Road and travel conditions on those routes of significance by November 2016 so we're kind of heading in that direction we have identified 10 major corridors in general metropolitan region and were actively pursuing 24/7 active management possibilities on these corridors automated traffic signal performance metrics is a significant development in the area of collecting and analyzing traffic signal timing in coordination data this is a cost effective solution and that could be used to identify operational deficiencies optimizing mobility and help manage traffic signal timing in maintenance we are currently assessing our communication network including hardware and software to generate automated signal performance measures integrated corridor management offers an opportunity to optimize and operate the entire transportation network which includes the arterial network the freeway network the bus system and the transit system these the the integrated corridor management is expected to eliminate or reduce congestion in the network not in a particular system connected vehicle as Sayed mentioned has the potential to change the way we travel the vehicle to infrastructure communication can significantly improve safety mobility and enhance environmental benefits one of the application that we can consider in the area of traffic signal timing is the signal phasing and timing information provided in real-time to the vehicle dashboards so that the vehicles are approaching an intersection would avoid the last-minute braking or also the possibility of running a red light what tools do we use for the signal asset management all regions have collected the traffic signal inventories maintenance level of service budget and work orders are in SA p ml OS is a performance-based budgeting tool which is used to define a Louis based on annual surveys in determining annual funding through the target area Louis our work orders are coded to a functional location which is a one-mile section of the roadway how do we go forward with the the asset management for traffic signals we're looking at both life cycle versus condition based and I was as many signals the average age or the useful life for traffic signal is approximately 25 years we're also looking at condition based approach and replace only when it's required so when we know we leverage the structural integrity data from staff bridge we also leverage our maintenance history to come up with the information on which yes that need to be replaced on a priority basis current condition on average traffic signal system is estimated to be at 73% of its useful life 28 percent or estimated beyond their expected life moving forward we do have an established traffic signal program and we are currently working on the statewide coordination and integration of traffic signal assets funding for the capital replacement is secured for FY 16 we have approximately 5.7 million dollars for FY 16 for capital replacement projects the criteria the capital replacement guidelines the interim guidelines that we worked on are based on age and condition which is expected to reduce the burden on the current maintenance funds we're also looking at implementing an integrated traffic signal asset management solution for traffic signals kind of an envision project selection process for traffic signals we have our ml OS budget which is in sa P our work orders are coded in s AP the traffic signal inventory is currently in a spreadsheet database DPD has also mapped the traffic signals for the state this information goes into the ames asset investment and management system and then it spits out a list for us and then we then reach out to the region and then consensus based prioritization is what we do for traffic signals when it comes to selecting the projects what does this mean to the regions and the stakeholders include asset management for traffic signals improved and consistent statewide application of asset management for traffic signals enhance decision-making on capital replacement projects and the system of the asset management system is not expected to add work but streamline and improve our project selection process he messages to communicate with your staff we have approximately 1900 signals statewide with the replacement cost of 500 million dollars average lifecycle cost in the range of 20 million dollars per year 28 percent of traffic signals estimated to be beyond their useful life 5.7 million kept replacement for and secured for FY 16 thanks to DT D on helping us with securing the funds while the program wasn't even there so thanks to DT D and Shawn Wetterling on helping us securing the 5.7 million dollars for capital replacement for traffic signals we're currently establishing the capital replacement guidelines for traffic signals I also wanted to kind of part or end this presentation with a part that think about how the future technology is going to impact how we maintain or add new assets into our system 30 years 20 years 10 years down the line would we still be doing traffic signals the way we do it or the ideas components the way we do it or is it going to be something different so the functional and the technical or technological obsolescence is something that we should consider moving forward into an asset management system thank you

Intelligent Transportation System (ITS) is a
combination of information and communication technologies used in
transportation and traffic management systems, which improve the safety,
efficiency, sustainability of transportation networks and reduce
traffic congestion. This report has been segregated based on components,
systems, applications, and geographic regions. Intelligent
transportation systems are being widely applied in several areas such as
fleet management and asset monitoring, traffic monitoring systems,
traffic signal control systems, collision avoidance systems, variable
traffic message signs, parking availability systems, traffic enforcement
cameras, and automotive telematics.
