| 摘要： | This synthesis study provides information on the use of five emerging technologies by transportation agencies for construction projects. The technologies explored are: 1. Global positioning systems (GPS) for layout, machine guidance, and quantity tracking; 2. Handheld computers for construction records (e.g., inspection, materials testing, and quantity tracking); 3. Automated temperature tracking for concrete maturity monitoring to optimize concrete placement for bridge and road construction; 4. Four-dimensional (4D) computer-aided drafting (CAD) modeling for constructability analysis and for improved communications (public outreach and visualization of project staging); and 5. Remote project monitoring with web-based video cameras. The TRB Committee on Application of Emerging Technologies (AFH30) described the need for exploiting current advancements in construction technology in the following terms: As the new century approaches and the baby boomers age and begin to retire, labor shortages are anticipated. Therefore, new construction automation, equipment, and techniques will be needed so the equivalent work can be performed with fewer workers. The automation is likely to prove more reliable, efficient, and cost-effective as well. |
