Planning Transportation Megaprojects: Paradoxes and Challenges in Planning Complex Projects

Temporal planning for transportation planning and scheduling

Many problems in transportation can be represented as flow problems, and can be optimally solved using efficient linear programming techniques [BIIM77] [BGAB83]. But in some cases this approach is seriously oversimplified. If the problem includes dependencies between different operations, planning is necessary. If the system parameters change dynamically, the assumptions on which flow models ar...

Waste Management Planning in Amirkabir Petrochemical Complex

The Amirkabir petrochemical complex (APC) is located in the south of Iran, on the northern coastline of the Persian Gulf. It has five different units which generate various waste estimated at 3115.98 ton/year. The objective of this study was to focus on the management of the processing wastes for minimizing the adverse environmental impacts. In order to properly manage and control waste generat...

Truth in Transportation Planning

Transportation engineers and urban planners often report uncertain estimates as precise numbers, and unwarranted trust in the accuracy of these precise numbers can lead to bad transportation and landuse policies. This paper presents data on parking and trip generation rates to illustrate the misuse of precise numbers to report statistically insignificant estimates. Beyond the problem of statist...

Iran’s Shift in Family Planning Policies: Concerns and Challenges

Iran’s significant success in implementing Family Planning (FP) during the past 25 years, has made it a role model in the world. The Total Fertility Rate (TFR) in Iran has dropped from 6.5 in 1960 to 1.6 in 2012, which is well below the targeted value of 2.2 for the country. Iran’s success story, however, did not merely root in the implementation of FP programs. In other words, families’ strong...
