GIS-based visualization of integrated highway maintenance and construction planning: a case study of Fort Worth, Texas

Abstract

Background: This paper reports on a case study of the use of visualization of geospatial data that is distributed across data sets and requires integration over time and space to aid decision makers. Like many State Highway Agencies (SHAs) in the United States, the Texas Department of Transportation (TxDOT) is organized along the traditional functional lines of planning, design, construction, maintenance, and operations. It has historically relied on experience and longevity of its staff to efficiently and effectively plan its construction and maintenance projects. Although functional boundaries of maintenance and construction are fairly clearly defined, there tends to be some overlap in projects that can be executed by either of the functional groups. The department currently does not have a robust integrated information system for identifying potential planning conflicts between its construction and maintenance projects. This has led to suboptimal use of resources, including overlapping plans for maintenance and mobility enhancement projects.

Application of Watson Visual Perception Model in Nanchang VI Visual Image Recognition Design

“…The research on modern urban image has laid an important theoretical foundation for the development of modern urban image [ 4 ]. It can be analyzed that “architecture” should not only have the function of use but also emphasize the aesthetic significance and aesthetic value [ 5 ]. Literature [ 6 ] proposes the concept of “city image” and emphasizes that city image is obtained by perceiving the urban environment, which still belongs to the category of urban planning.…”

Traffic Accident Spatial Simulation Modeling for Planning of Road Emergency Services

“…Furthermore, an inappropriate road network can increase the crash risk, as it determines how road users perceive their environment, meaning that the roadway offers instructions to the drivers on what they should be doing. Negative road engineering features include those where a road defect directly triggers a crash, or where some factor of the road environment misleads a driver and thereby creates human errors [56,57]. The results obtained in several recent studies [58][59][60] illustrate that human behaviors are the cause of accidents in almost 70% of cases (due to a lack of adherence to the laws and regulations, disregarding warning signs, a low level of education and a lack of familiarity with the minimum technical requirements of cars).…”

Framework for Spatial-Temporal Cross-Functional Planning of Projects by Highway Agencies

“…For example, a spot base repair project may need to be performed by the county maintenance section before a preventive maintenance or light rehabilitation of the surface course can be executed on the same asset. Similarly, some maintenance projects might be scheduled to precede a capital planning project planned for the same location (France-Mensah et al, 2018b). Such inter-related projects highlight the complex relationships between highway projects proposed by multiple functional groups.…”

“…Thus, the need to develop an integrated process to handle the dynamic and iterative nature of the planning process has been identified. The need for an efficient integrated management practice in transportation planning is explicitly exhibited in key federal laws passed over the last few decades: Surface Transportation and Uniform Relocation Assistance Act of 1987, the "Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA), " and the "Moving Ahead for Progress in the 21st Century Act" (France-Mensah et al, 2018b).…”
