Show CMAP Modeling Results: "Innovate" Scenario June 8, 2009 14 Finally, vehicle diagnostics monitor various vehicle systems for malfunction and communicate when repairs or adjustments are needed. While the vehicle side investment is the responsibility of private industry, public investment is also required to complete the system. Supporting technologies: Regional implementation of advanced vehicle technology would require public investment in the following supporting technologies: Field devices (properly equipped traffic signals and other roadside equipment) Communication infrastructure (wired and wireless) Private investment in supporting technologies is particularly important for the application of advanced vehicle technology, and could include: Vehicle on-board communication technology Vehicle-based sensors Vehicle-based software Operations centers to house staff and software Expected benefits This technology is expected to greatly reduce traffic incidents, which cause a large percent of daily roadway traffic congestion. This will also greatly reduce the costs in injury and property damage attributable to traffic accidents. The technology listed has the ability to address most of the major causes of traffic accidents. In addition, the lane keeping, adaptive speed control, and anti collision technology will allow vehicles to safely drive closer together at higher speeds than is currently possible. This will increase roadway capacity without investing in additional lanes. Decreased traffic congestion and smoother traffic will decrease the need for roadway expansion and reduce fuel consumption. Application within the transportation model The treatment of advanced vehicle technology within the transportation model is highly speculative. It was assumed that congestion would be decreased, as vehicles could safely operate at higher speeds or in closer proximity to each other; therefore congestion was reduced regionwide to account for this strategy. 10. Alternative fuels Advanced fuels provide a way to maintain personal mobility while reducing the harmful effects of fossil fuel combustion. Some potential fuels have been tested or are currently available, including biodiesel, propane, natural gas, methanol, hydrogen, ethanol, electricity and |
