      <title>Recruiting Minnesota's Next Generation of Public Works Engineers</title>
      <link>https://trid.trb.org/View/2676874</link>
      <description><![CDATA[Local transportation agencies in Minnesota continue to face the challenge of hiring and retaining workers. Over the past two decades, the Minnesota Local Road Research Board (LRRB) has funded projects and developed a series of resources that promote the different types of career opportunities local agencies offer. These past efforts have been focused on entry-level engineers and technicians. Most recently, the LRRB audience voiced a priority to find candidates to fill rural county engineer positions. A career path to become a public works engineer may not be known to civil engineering students; thus, contributing to the shortage. Additionally, the county engineer position requires being registered as a Professional Engineer (PE). In Minnesota this requires four years of work experience and passing an exam.]]></description>

      <title>Heritage valorisation of Madrid's bridges and stations. Applications and new dissemination tools</title>
      <link>https://trid.trb.org/View/2584425</link>
      <description><![CDATA[The heritage of public works combines technological and social values and is closely linked to the development of cities. Bridges and railway stations are two types of infrastructure of particular importance. On the one hand, they are the most visible elements of urban communication networks demonstrating the technology and the era in which they were built. On the other hand, they are hubs of activity in urban life and have cultural and symbolic significance. This article presents two related research and dissemination projects, analysing the bridges and railway stations of the city of Madrid. The methodology followed in their development is presented: selection, documentation, analysis and evaluation; transferable to other public works and cities. The resulting digital dissemination tools consist of rigorous databases based on interactive cartographies. These tools have more attractive and flexible interfaces than the traditional ones, offering new uses and applications. Geolocation and the diversity of content (text, images, 3D models, videos, etc.) ensure a comprehensive technical and cultural understanding of the heritage, while highlighting its role in shaping the city. The projects serve as a model for heritage enhancement and communication with citizens through digital applications and innovative dissemination tools.]]></description>

      <title>Urban Waterfront Placemaking: Creating Improved Public Space on an Old Municipal Pier</title>
      <link>https://trid.trb.org/View/2559433</link>
      <description><![CDATA[The Imperial Beach Pier, owned by the San Diego Port District (Port), is an open-ocean fishing pier that provides recreational space for the local community and visitors alike. This paper summarizes the challenges associated with introducing a unique, visually compelling canopy structure onto a 35-year-old timber and steel pier. The wind and wave exposure, coupled with the need to maintain the canopy’s visual elegance, made for a challenging assignment, both in engineering and creating art. The marine engineering challenges required creative problem-solving, and the outcome was an improved public space that brings life to an aging structure.]]></description>

      <title>Use of Dashboards for Winter Operations</title>
      <link>https://trid.trb.org/View/2506261</link>
      <description><![CDATA[Public works agencies at state and municipal levels have invested a large amount of personnel and funding resources in dashboards to improve winter maintenance operations. The types and amounts of data gathered and performance measures used to track and monitor winter maintenance operations vary by agency. Due to these differences, there is a need to conduct a synthesis of agencies' practices in using dashboards for winter maintenance operations, which is the genesis of this research project. This report will focus on all aspects of dashboarding to provide the most complete understanding for state winter maintenance managers to track and manage winter maintenance operations. This report summarizes a literature review, survey of practices and case studies of 5 agencies. This final report will serve as a reference guide for state department of transportations (DOTs) who are considering implementing or enhancing their winter maintenance operations dashboards.]]></description>

      <title>Iowa Public Works Service Bureau</title>
      <link>https://trid.trb.org/View/2509061</link>
      <description><![CDATA[Over the past year, a study to determine the interest in developing a public works service bureau in the state of Ohio was conducted. The premise is that a public works service bureau would provide a mechanism of communication and information exchange regarding emerging issues as well as to improve efficiency of public works operations.

Following positive responses to a questionnaire sent to all cities with a population of at least 250 people, the organizational structure and costs associated with a public works service bureau was examined.

The recommended organizational structure calls for development of a service bureau within the umbrella of the Statewide Urban Design and Specifications (SUDAS) program at Iowa State University. Permanent funding for the service bureau is proposed as an off-the-top allocation of 1/8 of 1% from the city portion of the Road Use Tax fund. That funding mechanism would mirror the type of funding of the Iowa County Engineers Association Service Bureau.

PHASE 2 CONCEPT
It is likely to take the better part of two years to successfully complete a legislative change and the required administrative processes to set up the service bureau street construction funding. Therefore, interim financing for startup activities is critical. The Phase 2 proposal would involve establishing the Iowa Public Works Service Bureau within the SUDAS program by initiating the activities identified in the approved recommendation from the feasibility study (IHRB Project TR-761).

The recommended actions include a two-year startup. The first year of Phase 2 involves expanding SUDAS staff to include a webmaster/programmer and a subcontractor to work on the initial database applications. As that work is being accomplished, SUDAS staff will initiate discussions with involved organizations and their members about support for the proposed legislative change to establish the off-the-top allocation from the Road Use Tax Street Construction Fund.

The second year of Phase 2 would involve the addition of a second programmer in order to expand database applications. In addition, a major focus will be working with the Governor’s office and the legislature to pass the Road Use Tax off-the-top allocation to create the permanent funding source. 

Establish the Iowa PWSB website, market the service bureau to cities throughout the state, initiate and populate database applications, and modify the Road Use Tax law to establish a public works service bureau fund through designation of a 1/8 of 1% off-the-top allocation.]]></description>

      <title>Using Genetic Algorithm to Optimize Land Use Development Plan in Hong Kong</title>
      <link>https://trid.trb.org/View/2263963</link>
      <description><![CDATA[Optimization of land use development plan is important particularly in condition of heavy concentration of urban population such as in Hong Kong. With the growth of population in Hong Kong, there is a need to develop some new residential areas continuously and to decentralize population in the outlying areas such as the satellite towns and/or new towns. The land use planning consists of identifying and selecting potential development areas to meet the expected land requirements. The optimal land use development problem relates to the allocation of population with optimal objective function value. In this case the land production cost includes formation of new areas, construction of public works infrastructure, and provision of other utility services. The optimal land use development plan is chosen from a large number of potential development areas and potential population allocation. This problem can be formulated as a 0–1 programming problem mathematically. In this paper, the genetic algorithm is used to solve the 0–1 programming problem in which some new land use plans are identified in Hong Kong so as to minimise the total development and transportation cost. It is the first work to apply genetic algorithm for land use problem in practice. The developed model will advance this subject and help the authorities decide which new residential areas should be considered for detailed investigation. The Hong Kong 2006 planning data is used for case study.]]></description>

      <title>Cambridge Underground: Challenges of Sewer Separation and Stormwater Management</title>
      <link>https://trid.trb.org/View/2218577</link>
      <description><![CDATA[Cambridge is an old city that is seriously in need of the infrastructure improvements that are now being implemented. Sewer separation and stormwater management projects will alleviate the problem of flooding and threats to public health caused by untreated wastewater discharged to low-lying neighborhoods and the Charles River during heavy rainstorms. Since 1998, S E A Consultants Inc. and Montgomery Watson Harza (S E A/MWH) have been working with the Cambridge Department of Public Works to pinpoint problems within the existing system; develop ways to achieve the program objectives; and plan, design, and oversee construction of over $325 million in city-wide infrastructure improvements over the next 15 years. Unconventional construction methods in heavily developed urbanized areas such as use of large underground storage tanks, maximizing use of surface storage potential, use of best management practices to reduce floatables and sediment discharges to the Charles River, and applications of trenchless technologies to minimize construction disruptions while improving the infrastructure have been highlights of the program. The paper describes various aspects of the Cambridge sewer separation and stormwater management program, the condition of the existing infrastructure, improvements needed to support future growth, and innovative techniques used to address water quality and quantity considerations. Planning, design, construction, utilities, traffic and pedestrian management, and community participation will be explained as they relate to this program.]]></description>

      <title>A Modelling Framework for Construction Supply Chain Simulation Based on Multi-Agent</title>
      <link>https://trid.trb.org/View/2282168</link>
      <description><![CDATA[Construction industry is specifically full of complexity and difficulty, specifically in large-scale public works project. Construction Supply Chain (CSC) management is investigated as an effective and efficient measure and strategy to deal with the problems in construction. But cooperation and decision making between partners are still key and difficult problems in CSC management. In this paper, the authors propose a simulating model for CSC management based on multi-agent method under analysis of the special characters in CSC. Then, the authors analyze the model classes in detail and the dynamic definition and structure of the simulation. At the end of the paper, the functions of the model are summarized and future research directions proposed.]]></description>

      <title>On the influence of infrastructure availability on companies' decisions toward modal shift and relocation of falicities</title>
      <link>https://trid.trb.org/View/2173764</link>
      <description><![CDATA[Reduced availability of transport infrastructure affects highly dependent global supply chains (SCs), leading to modal shifts in the short term. Since relocation decisions of facilities may result in the long term, this paper evaluates companies’ business decisions in reaction to availability reductions of inland waterway transport (IWT). A transport model evaluates the impact of reduced infrastructure availability through heuristic optimization based on the Traveling Purchaser Problem. The resulting increase in operational costs is used to assess the probability of relocating facilities based on a Facility Location Problem (FLP) which enables deriving the benefit from infrastructure conditions. The study identifies critical thresholds for infrastructure availability that affect companies’ relocation decisions regarding the maintenance of public infrastructure. The case study exhibits actual critical infrastructure assets. Insights into the decisive consequences of companies’ decisions are given, and awareness of the relevance of infrastructure investments on local areas’ attractiveness is raised. The results imply considering public infrastructure investments in maintenance for private business locations. The paper highlights a new way to sustain local industries and connects short-term agility and long-term resilience with companies’ decisions and the exogenous factor infrastructure availability. The applied use case focuses on the barely studied waterway infrastructure that gains importance in light of sustainability and climate change.]]></description>

      <title>Pitfalls and Potholes: Examining the Impacts of Covid-19 on the North Carolina Department of Transportation</title>
      <link>https://trid.trb.org/View/1760727</link>
      <description><![CDATA[Covid-19 has had devasting impacts across society and government worldwide in a span of a few short months. The disruption has been nothing short of catastrophic to the public and private sectors across the country and the responses have run the gamut. This commentary discusses the unique impacts of the global pandemic on public works and transportation at the state and local level through the lens of intergovernmental agreements and public private partnerships in the state of North Carolina. The North Carolina Department of Transportation (NCDOT) has realized budget deficits the previous two fiscal years with a significant projected deficit for the current fiscal year; however, NCDOT was not blind to a future of instability. Policy implications are clear: changes must be considered that reduce the likelihood of significant budget shortfalls and reasonable measures taken to provide practicable levels of service throughout public works.]]></description>
