The Indiana Department of Transportation (INDOT), in response to requests from the construction contracting community, has chosen to examine how to facilitate their contractors’ use of three-dimensional machine control (3D-MC) systems, especially GPS-based systems. INDOT recognizes that the prerequisite 3D project model, if available in its intelligent electronic form, may be leveraged by both INDOT and its project partners to automate the performance of tasks other than construction. Therefore, INDOT was compelled to initiate this study to investigate the state of technology and the experiences of other state transportation agencies (STAs) and to synthesize that information to formulate recommendations for …

Design data collection involving the use of Lidar instrument, in conjunction with GPS proves to be very effective. Data required to model two bridges over the I-70 was collected on a single day, involving five and six sessions with Lidar equipment. Even though the data was collected on two bridges, it did not cause any disruption of the traffic, either on the Interstate or on the bridges. A major cause of concern during survey activities, particularly along interstates is safety, both for the motorists as well as the people involved in data collection. Lidar data collection was found to be …
Improving Efficiency Of Indot Traffic Data Collection Using Gps Devices, Shuo Li, Karen Zhu, Boudewijn H. W. Van Gelder, John Nagle, Carl Tuttle

INDOT has utilized many new technologies to reduce travel delay, mitigate traffic congestion, and enhance public and employees’ safety. Many projects are underway, including re-timing of most existing traffic signals and pavement maintenance and rehabilitation. To evaluate signal system performance, prioritize alternatives of improvement, conduct before and after studies and investigate work zone safety, it requires a large amount of traffic data such as travel time, speed and delay. Issues, such as safety, efficiency and cost, may arise associated with the current methods. For the current manual or automatic data collection, it usually requires two operators, a driver and a …
Automating Field Data Collection In Maintenance Operations, Bob G. Mccullouch
Automating Field Data Collection In Maintenance Operations, Bob G. Mccullouch
JTRP Technical Reports
Field data collection and management in DOT organizations requires a considerable amount of resources in the form of personnel and management systems. Recent studies performed by the researcher revealed that an average of 30-50% of some field supervisory personnel's time is spent on processing field data paperwork. This is a considerable amount of time spent on an undesirable task and is taking these employees away from more important job duties. This project automated two maintenance field data collection functions. One was a Crew Day Card, which is a card used by a maintenance crew to document the activity performed. Information …
Use Of Gps To Enhance Mapping By Photogrammetry, Robert D. Feeney, James Samuel Bethel, Boudewijn H. W. Van Gelder, Steve Johnson

This research has sought to demonstrate the benefits of kinematic GPS in conjunction with photogrammetric aerial triangulation for mapping purposes. The work was performed with the existing INDOT aerial camera which is quite old, and while this affected the accuracy of the results, the demonstration of capability with a likely potential for excellent results was achieved. Ground point accuracies from the strip were in the sub-meter range with only a single control point. This is contrasted with full-model control requiring 50-80 control points for such a strip. In order to bring accuracies down to an acceptable level, i.e. sub decimeter, …

The report presents the findings of a study that investigated the potential uses of new technologies in INDOT. A survey of state transport agencies were conducted and the major groups of technologies identified are: CADD, GIS, Advanced Survey Techniques, Knowledge-Based Expert Systems, Planning and Programming Mdels, and a workshop with the INDOT executive staff were conducted to determine the priority areas for advanced technology applications. Suggestions were then made for the development of a new technology program within INDOT.
