Improved Annual Average Daily Traffic (AADT) Estimation for Local Roads using Parcel-Level Travel Demand ModelingWang, Tao 29 March 2012 (has links)
Annual Average Daily Traffic (AADT) is a critical input to many transportation analyses. By definition, AADT is the average 24-hour volume at a highway location over a full year. Traditionally, AADT is estimated using a mix of permanent and temporary traffic counts. Because field collection of traffic counts is expensive, it is usually done for only the major roads, thus leaving most of the local roads without any AADT information. However, AADTs are needed for local roads for many applications. For example, AADTs are used by state Departments of Transportation (DOTs) to calculate the crash rates of all local roads in order to identify the top five percent of hazardous locations for annual reporting to the U.S. DOT.
This dissertation develops a new method for estimating AADTs for local roads using travel demand modeling. A major component of the new method involves a parcel-level trip generation model that estimates the trips generated by each parcel. The model uses the tax parcel data together with the trip generation rates and equations provided by the ITE Trip Generation Report. The generated trips are then distributed to existing traffic count sites using a parcel-level trip distribution gravity model. The all-or-nothing assignment method is then used to assign the trips onto the roadway network to estimate the final AADTs. The entire process was implemented in the Cube demand modeling system with extensive spatial data processing using ArcGIS.
To evaluate the performance of the new method, data from several study areas in Broward County in Florida were used. The estimated AADTs were compared with those from two existing methods using actual traffic counts as the ground truths. The results show that the new method performs better than both existing methods. One limitation with the new method is that it relies on Cube which limits the number of zones to 32,000. Accordingly, a study area exceeding this limit must be partitioned into smaller areas. Because AADT estimates for roads near the boundary areas were found to be less accurate, further research could examine the best way to partition a study area to minimize the impact.

Využití dotačních titulů pro výstavbu a opravy obecních komunikací v Jihočeském kraji / The use of subsidies for the construction and repair of local roads in the South Bohemia RegionCIGÁNKOVÁ, Petra January 2014 (has links)
In the context of this thesis was analyzed the current state of the use of subsidies for the construction and repair of local roads in the South Bohemia Region in the period 2007-2013. The outcome of this work are four proposed measures reflect comments mayors to grant titles. These measures lead to increased efficiency grants and disclosure of municipalities in the region.

Vysoké Mýto - napojení na R35 při postupné výstavbě / Vysoké Mýto - connection to motorway R35, phase of constructionNovák, Martin January 2014 (has links)
The thesis deals with the stages of development of Vysoke Myto road network with an emphasis to design an optional diversion of the traffic from the town itself even before the planned R35 is finished. The designed solution, including road connections to the present and future network, is to be functional, utilizable and economically desireable in all the stages of development.

Blansko - JOK Masarykova x Sušilova / Blansko - roundabout Masarykova x SusilovaKočiš, Michal January 2022 (has links)
The subject of the thesis is a design of variants of the solutions of the existing intersection streets of Masarykova, Sušilova and Nádražní in the town of Blansko. The reason for its processing is to find out the possibility of a prospective solution of the intersection. The output of the work is proposed two variants and their comparison in terms of capacity and traffic. The work also contains an evaluation of the traffic survey, capacity assessment of prospective intensities, price estimation of both variants and verification of the passage of the roundabout. The proposed variants improve static transport in the area.
