A 37-year-old diesel mechanic employed by a railroad transportation company died when his loaded utility truck collided with the rear of a semi-trailer on a four-lane interstate highway. The mechanic was driving at highway speed during daylight hours when he failed to stop in time and struck the semi, which was moving slowly in traffic that had backed up due to a car fire two miles downstream. There was severe damage to the mechanic's truck, with underside of the cab and intrusion up to the right rear tires of the trailer ahead. The force of the collision caused a chain reaction, pushing the struck tractor-trailer forward into a second tractor-trailer that had stopped in backed up traffic. Fire and rescue responders arrived from the nearby town located four miles away. The mechanic, who was wearing a safety belt, suffered blunt force trauma as a result of the collision and was pronounced deceased at the scene. He was extricated by mechanical means from the truck cab and was found holding a cell phone. Law enforcement officers' examination of the phone activity revealed the mechanic had exchanged several voice/text messages prior to the crash and was initiating a voice/text message application at the time of the collision. The driver's failure to notice the tractor trailer ahead and stop in time was attributed to texting. Drivers of the other two vehicles were not severely injured.

The goal of this work was to develop activity-based learning materials for the introductory transportation engineering course with the purpose of increasing student understanding and concept retention. These materials were to cover intersection operations from a multimodal transportation approach. The initial framework was to create a set of 4 activities, the first activity focused solely on automobile transportation, and the subsequent activities adding one additional transportation mode each. For the final work, the existing sequence of material in the textbook was used for activity development. The final work included the development of a handout for Dr. Kytes critical movement analysis method, a queuing systems field lab, a pedestrian and bicycle level of service lab, and a transit level of service lab. The lab activities provided an active learning experience, two focusing on non-auto modes. These activities facilitated a fundamental and broad understanding of core concepts in transportation engineering. This work has provided me with a better perspective on instruction of this topic and with specific future goals, including better integration of multimodal transportation into the existing curriculum, addressing issues in the textbook, and fine-tuning the work that was previously completed.

In response to the Fuel Economy and Greenhouse Gas (GHG) emissions standards, automobile manufacturers will need to adopt new technologies to improve the fuel economy of their vehicles and to reduce the overall GHG emissions of their fleets. The U.S. Environmental Protection Agency (EPA) has developed the Optimization Model for reducing GHGs from Automobiles (OMEGA) to estimate the costs and benefits of meeting GHG emission standards through different technology packages. However, the model does not simulate the impact that increased technology costs will have on vehicle sales or on consumer surplus. As the model documentation states, While OMEGA incorporates functions which generally minimize the cost of meeting a specified carbon dioxide (CO2) target, it is not an economic simulation model which adjusts vehicle sales in response to the cost of the technology added to each vehicle. Changes in the mix of vehicles sold, caused by the costs and benefits of added fuel economy technologies, could make it easier or more difficult for manufacturers to meet fuel economy and emissions standards, and impacts on consumer surplus could raise the costs or augment the benefits of the standards. Because the OMEGA model does not presently estimate such impacts, the EPA is investigating the feasibility of developing an adjunct to the OMEGA model to make such estimates. This project is an effort to develop and test a candidate model. The project statement of work spells out the key functional requirements for the new model.

In an era of limited resources and a proliferation of data, there is increasing pressure to conduct careful evaluations of the economic, environmental, and equity effects of investments and policies that influence transportation and land-use systems. This report compares performance measures recommended to achieve desired goals and reviews the literature to determine the degree to which these measures have been implemented and what they indicate about the relative effectiveness of land-use, transit, and automobile pricing policies. Despite the variation in methods and performance measures implemented in the studies reviewed for this report, the synthesis of study results suggests the direction and relative magnitude of change resulting from different types of policies, as well as potential biases introduced by omitting the representation of the land-use and transportation interaction. Overall, the performance measures indicate that carefully designed transit, land-use, and automobile pricing policies may improve travel, economic, environmental, and equity conditions for communities. However, transit and peak-period automobile pricing policies can, in some situations, lead to negative performance outcomes across some or all measures, as illustrated in studies that explicitly represent the land-use and transportation interaction.

Because the classic PID control doesn't satisfy the demand of automobile ABS in all conditions and it is short of an ability of identifying road surface,fuzzy control is short of an ability of remove systemic stable error and it doesn't make automobiles keep higher control precisions,a dynamic mode of the wheels is built when an automobile is braking at first,aiming at automobile ABS,a immune PID control algorithm based on classic PID is presented and used in automobile ABS system.Compared with the classic PID control algorithm and fuzzy control algorithm,the simulation result shows that the immune PID control algorithm has a shorter stabilization time,a smaller excess of system output,fewer response time and shorter braking distance,it is superior to the classic PID control algorithm and fuzzy control algorithm.The immune PID control algorithm has a higher application value.
