Abstract
The arterial roads are the most auto-oriented street type in an urban road network, as they carry the largest numbers of vehicles with relatively high speeds between different districts, as well as from and to other road categories. However, in many cities, particularly in developing countries, the arterials are highly congested and unsustainable for a variety of reasons. One reason is that the right-of-way becomes constrained; i.e. the transport demands (mainly motorized) are continually increase within a finite right-of-way. Another reason is that there is a rising concern about providing sustainable mobility systems which can guarantee the development of mobility in an attractive way, i.e. clean, safe and smart. Thus, the sustainable development of arterial roads needs the introduction of rapid transit and the application of intelligent traffic management. Otherwise, the high traffic volumes and speeds increase the need for safe pedestrian treatments. Therefore, the main objective of this thesis is the development of a flexible planning process which can be used as a tool to produce and evaluate different strategic solutions (or scenarios), each of which includes different plausible improving actions. These solutions should be tailored to the specific road location, conditions and physical constrains, as well as enable the road to cover the expected travel mobility in a sustainable manner. Since an arterial is often a long-distance road, the traffic micro-simulation technique can be applied to investigate the impact of proposed actions on the different segments of the arterial; individual and integrated. This means that the arterial should be divided into homogenize segments, regarding right-of¬way, geometric alignment, and traffic condition. The solutions are then yielded subjected to a trade-off analysis taking into consideration technical, economical, environmental, and social criteria. The proposed planning process is applied to the main arterial in Alexandria ”The Cornish Road”, as a case study. The whole corridor is modeled and calibrated using the commercial Software VISSIM. Then, the whole corridor model is divided into several homogenize segment models for micro- simulation investigation. The aim is to identify the proper actions that can improve the traffic conditions on each segment at each specific location. Some scenarios are then formulated for whole corridor, containing sustainable actions that are well-matched for all segments. The scenarios are subjected again to micro¬simulation to explore their impacts; individual for each segment and integrated for the whole corridor. These impacts with other quantitative and qualitative indicators are subjected to trade-off-analysis to select the preferred scenario. The selection of the preferred alternative is provided through a balanced assessment of impacts of each scenario (positive and negative sides), as well as the trade-offs (advantages and disadvantages) among them regarding mobility, safety, comfort, and accessibility, as well as the complementary and competing perspectives of the street users and the community and environmental objectives as well. The application confirms not only the practicality and capability of the proposed flexible design process for improving traffic conditions and safety, but also can provide more mobility with less traffic.
