Trip Time Comparison of Automated Guideway Transit

Abstract :-
This is a Civil enginerring thesis on trip time comparison of automated guideway transit. Automated People Movers (APM) and Personal Rapid Transit (PRT) are two of the main transportation modes in the realm of grade-separated automated transit technology. APMs can be seen in various US locations and resemble traditional heavy rail or light rail, as they all operate on fixed routes, but APMs are completely automated. PRT systems, which are not well established in the US, use low capacity vehicles to transport passengers directly from their origin to their destination, Continue reading Trip Time Comparison of Automated Guideway Transit

Traffic Signal Timing for Urban Evacuation

Abstract :-
This is a Civil thesis which studies approaches for signal timing to facilitate evacuation and response in the event of a no-notice urban evacuation. A simulation model was constructed with data from Washington, D.C. Experimental results indicate that significant trade-offs exist in setting timing plans as long cycle lengths can lead to reduced evacuation times, but at the expense of delay on minor roadways. Best compromise plans employ cycle lengths greater in length than used in ordinary peak hour plans, giving significantly more green time to the main evacuation routes than to minor roadways as used in peak hour plans.

Hydrologic Design of Green Roofs

Abstract :-
Green roofs are increasingly being used as part of primary urban strategies to improve storm water management and reduce energy costs. Different methods for green roof design are based on different assumptions and parameters. However, the input parameters are uncertain, which influences design accuracy. A mathematical model was developed to simulate the water movement across and through a green roof. This model was used to assess the sensitivity of the hydrological response of a green roof to roof and rainfall characteristics. Peak discharge rates and depths of runoff mainly depend on the rainfall characteristics. Continue reading Hydrologic Design of Green Roofs

Using Radio-Frequency Identification Technology to Measure Asphalt Cooling

Abstract :-
Realistic prediction of asphalt temperatures as a function of time during paving is essential for optimizing compaction operations. Continued compaction after the asphalt lift has dropped below a critical threshold temperature may result in particle breakage and degradation of the material properties. To address this issue, this study evaluates the feasibility of using Surface Acoustic Wave (SAW) based Radio-Frequency Identification (RFID) technology to measure HMA temperatures via wireless sensors during paving.

Phased Development of Rail Transit Routes

Abstract :-
This thesis develops a method for optimizing the construction phases for rail transit extension projects with the objective of maximizing net present worth and examines the economic feasibility of such extension projects under different financial constraints. A Simulated Annealing Algorithm is used for solving this problem. A rail transit project is often divided into several phases due to its huge capital costs. A model is developed to optimize these phases for a simple, one-route rail transit system, running from a Central Business District to a suburban area.

Speed-flow-density Study of two different Indian roads and their comparisons

Abstract :-
In this work speed -flow-density study of an Indian road has been conducted. Data has been collected using video camera and later decoded in computer. This data is very essential to estimate capacity of an Indian road. Since the collected data is of a narrow density domain, capacity prediction from this data is not promising. One of the data is collected in Chennai and another data is from Rourkela .Both the data’s were compared statistically. For both the data’s Z-value is calculated and it is compared with Z-critical to define whether both the data’s are same or different.
